Version 1.13.0-rc01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/8c4a5fab030e62e6dac58c45f5fff974facf903f..57354ca42849ed417dfe0f797132477674d917e0/compose/foundation). **API Changes** - `Modifier.border` now consistently uses the outline size when rendering borders. Use `ComposeFoundationFlags.isBorderMatchesOutlineBoundsFixEnabled` to temporarily disable this if it causes issues. ([I3e171](https://android-review.googlesource.com/#/q/I3e171be3f77c0b9794ad70de9d7be36a2adcf20c)) ### Version 1.13.0-beta02 October 21, 2026 `androidx.compose.foundation:foundation-*:1.13.0-beta02` is released. Version 1.13.0-beta02 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/55d45bc889e6e54d26f897e1299b3f5d6ca78acb..8c4a5fab030e62e6dac58c45f5fff974facf903f/compose/foundation). **Bug Fixes** - `Modifier.border` now uses a new more performant implementation. You can disable this using `ComposeFoundationFlags.isNewBorderImplementationEnabled`. If you run into issues and need to disable this flag, please file a bug. ([I4c3b3](https://android-review.googlesource.com/#/q/I4c3b326711b5af04e94222d9564491b6d48b71f0)) - `Modifier.border` now supports rendering generic / polygon shapes with a runtime shader, when using the new border implementation. ([I128ca](https://android-review.googlesource.com/#/q/I128cacfaad9825dcef47d479d71291357fe48463)) - Fixes an edge case bug with rendering certain rounded rectangle outlines in `Modifier.border`. `ComposeFoundationFlags.isRoundedRectangleBorderRenderingFixEnabled` can be used to disable this change if it causes issues. ([I19141](https://android-review.googlesource.com/#/q/I191415aaa3e9b2a7816c14b7ebd0fc1ed0a90931)) - Fixed an issue where the cache window incorrectly re-prefetched items when a previously prefetched item became visible. [I43ca7b4](https://android-review.googlesource.com/q/I43ca7b4d393fffa15be219144c1312c710a6021a) ### Version 1.13.0-beta01 October 07, 2026 `androidx.compose.foundation:foundation-*:1.13.0-beta01` is released. Version 1.13.0-beta01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/58589a3cd45bacbb3ad7bbdc52836f6e055340be..4c2d8a03f5933cc395e104d9abe368fb4fe3c555/compose/foundation). **API Changes** - Added `@FloatRange` and `@IntRange` annotations to `PolygonShape` and `PolygonShapeScope` factory parameters, and restricted `innerRadiusRatio` in `PolygonShape.star` and `PolygonShape.pillStar` to `(0f, 1f)`. ([I47ea3](https://android-review.googlesource.com/#/q/I47ea32a37c1a9652de48ed3a2e24e20b7d3c3cd0)) - Updated `PolygonShape` APIs: moved `CornerRounding` to top-level with `dp()` and `fraction()` factories, replaced `transformed()` and `scaledToFit()` extensions with in-place mutable `PolygonShape.transform(PolygonShapeTransformScope.() -> Unit)` and `PolygonShape.copy()`. ([If5970](https://android-review.googlesource.com/#/q/If5970afe91c37146e7de4521ca916e59d31b924e)) - Fixed a bug where requesting focus on a `BasicTextField` before the window was focused (e.g. in `onCreate`) caused the software keyboard to not appear. `BasicTextField` now waits for the window to gain focus before starting the text input session. If this causes problems for developers, you can revert to the previous behavior by setting `ComposeFoundationFlags.isTextFieldWaitWindowFocusForInputSessionEnabled` to false. ([I4206b](https://android-review.googlesource.com/#/q/I4206b22840b21eb2ede6a31d627dec9cb7afb5ca)) - Libraries now target Kotlin 2.2 and require kotlinc 2.2 ([I82396](https://android-review.googlesource.com/#/q/I823967fe6b9524b448184ef366c562316bd6a323), [b/498369605](https://issuetracker.google.com/issues/498369605)) - Added a `styleLayer()` method to `CommonStyle` that declares that all properties is in a layer will take precedence over properties set in a lower layer. The `state()` method (and state helpers like `pressed()`) now implicitly create a layer. ([I24473](https://android-review.googlesource.com/#/q/I244739d8798965375829602cc6113d163d1d64fa)) **Bug Fixes** - Fixed an issue in `FlexBox` where setting `alignContent`(`FlexAlignContent.Stretch`) incorrectly forced child items to stretch with line. ([Ida156](https://android-review.googlesource.com/#/q/Ida156115c8c86274da06d77bbc75d047a838f498)) - Fixed an issue in `FlexBox` where a single wrapped line (`FlexWrap.Wrap` or `FlexWrap.WrapReverse`) was forcibly expanded to the container's minimum cross-axis constraint, causing `alignContent` and `alignItems` to misalign items. ([I038b1](https://android-review.googlesource.com/#/q/I038b142846f2ea0ea1be848488c4a5e9813e44e6)) - Fixed an `IllegalStateException` crash when updating `consumeWindowInsets`, `windowInsetsPadding`, or `onConsumedWindowInsetsChanged` on detached modifier nodes, such as during `movableContent` movement. ([I80ae5](https://android-review.googlesource.com/#/q/I80ae50e3ad4b40a1aefc46168f2de71ea7b492fc)) - `androidx.lifecycle:lifecycle-runtime` dependency was updated to 2.10.0. This version is required for bundled lifecycle runtime lint checks to run with AGP version 9.5.0-alpha04 or later. ([I99bfd](https://android-review.googlesource.com/#/q/I99bfdb355ffd7f1083dbdac4167b1f5577740116), [b/556807521](https://issuetracker.google.com/issues/556807521)) ### Version 1.13.0-alpha03 September 09, 2026 `androidx.compose.foundation:foundation-*:1.13.0-alpha03` is released. Version 1.13.0-alpha03 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/f3ed195f0c9ef9eafe437351d974c9ec49ecc2ea..58589a3cd45bacbb3ad7bbdc52836f6e055340be/compose/foundation). **API Changes** - Adds support to specify the style of individual parts of a compound composable (such as `TextField` or `DatePicker`) directly in the style parameter of the composable. This enables, for example, creating a `TextField`-like composable that allows customizing each of the decorator boxes using a style, enabling them to be overridden at a theme level or at the call site. ([I43c0f](https://android-review.googlesource.com/#/q/I43c0f1456cae4dd8ca8ca0212b5fe35e7813e617)) - Material 2 text field overloads that accept `value, onValueChange` parameters are deprecated. Please migrate to the overload that uses `TextFieldState` to hoist its state. ([I6b841](https://android-review.googlesource.com/#/q/I6b841e6850afbc22bec2424c3762927ec4f65670), [b/556234973](https://issuetracker.google.com/issues/556234973)) - Removed `@ExperimentalFoundationApi` annotation from `undoState` in `TextFieldState`. ([I93a44](https://android-review.googlesource.com/#/q/I93a44b649ae73e456d904cda9c9b12007b8ff3a9)) - Add default configuration objects for each lazy layout containing the default values used in the corresponding `@Composeable` functions. Currently only contains the default cache window for each layout. ([I58633](https://android-review.googlesource.com/#/q/I5863328b8091e28638d709c56d9b6caecf2abfca)) - Flag `isUsingDynamicDefaultCacheWindowIn[List|Grid|StaggeredGrid]s` when enabled will cause lazy layouts to use a cache window that uses the average size of visible items to prefetch ahead of the viewport with a minimum ahead window of 10% of the viewport and a maximum ahead window of 50% of the viewport. ([I59212](https://android-review.googlesource.com/#/q/I59212240a2719136277f635ea6c7ba59132fe188)) - Deprecated `LazyListPrefetchStrategy`, `LazyListPrefetchScope`, and `LazyListPrefetchResultScope`. Prefetching behavior should be configured using `LazyLayoutCacheWindow` on `LazyColumn` or `LazyRow`. `LazyLayoutCacheWindow` provides a declarative, viewport-based caching mechanism that automatically prepares items ahead of and keeps items behind the visible window without requiring complex imperative scheduling callbacks. The new API is simpler and requires less configuration steps than `LazyListPrefetchStrategy`. ([I1fa2d](https://android-review.googlesource.com/#/q/I1fa2d852d6579d1656e13242f9b00837b9b807b5)) - Adds `PolygonShape.transformed` and `PolygonShape.scaledToFit` extension functions in Compose Foundation for transforming and fitting polygon shapes. ([I3f327](https://android-review.googlesource.com/#/q/I3f32730534fa3739dc4e0c7eaac036284e98721b)) - This change refactors the Styles API into two independent pieces: the Styles DSL and the modifiers that are configured by the DSL. The previous `Style`-based implementation is still present but will be deprecated and removed. Any uses of it should be replaced with the new `CommonStyle` based API. - Key components introduced: - `CustomStyle` \& `CommonStyle`: Base interfaces and merging helpers for declaring composable styles. - `StyleResolver`: Resolves style properties in composition and binds to layout nodes via `Modifier.styleResolver`. - `Modifier scopes`: `Modifier.appearance`, `Modifier.placement`, and dynamic callback-based `Modifier.padding` and `Modifier.graphicsLayer`. - Property primitives: `stylePropertyOf`, `styleLocalOf`. - Types useful for style properties: `Breadth`, `Fill`, and `Shadows`. - The new modifiers are useful for implementing a design system using the Styles API but are not required. A design system may use these modifiers or provide its own. ([Ieb8cc](https://android-review.googlesource.com/#/q/Ieb8ccd0560bb32a179d64a53e028a0117d903db2), [b/549921960](https://issuetracker.google.com/issues/549921960)) - Removed `ExperimentalFoundationApi` annotation from `TextFieldBuffer` APIs that track the changes ([I546a7](https://android-review.googlesource.com/#/q/I546a75f19ca406cbb637fa48e325c2d5fad58a17)) - Introduces `MorphPolygonShape` in Compose Foundation for morphing animations between polygon shapes, along with `toPolygonShape()` converters for `RoundedCornerShape` and `CutCornerShape`. ([Ic5a89](https://android-review.googlesource.com/#/q/Ic5a8981b6bf62a67e8b191bfb6c011b50b476464)) - Introduces `PolygonShape` in Compose Foundation for rendering regular, star, and custom rounded polygons with corner smoothing. ([I0b99d](https://android-review.googlesource.com/#/q/I0b99d9ad53f21a71f283e830e63806add4b3b51b)) - `BasicTextField` overloads that accept `value, onValueChange` parameters are deprecated. Please migrate to the `BasicTextField` overload that uses `TextFieldState` to hoist its state. ([I636bf](https://android-review.googlesource.com/#/q/I636bf0af4334ce04a8eb9e80b8b2b0d1b6c905ae), [b/552879150](https://issuetracker.google.com/issues/552879150)) - Inline with `BasicTextField(value, onValueChange)`, `VisualTransformation` is also deprecated since it is only exposed through this `TextField` flavor. Existing transformations should migrate to `OutputTransformation`. ([I636bf](https://android-review.googlesource.com/#/q/I636bf0af4334ce04a8eb9e80b8b2b0d1b6c905ae), [b/552879150](https://issuetracker.google.com/issues/552879150)) - Providing `LazyLayoutCacheWindow` and `LazyListPrefetchStrategy` via `LazyListState` has been deprecated in favour of providing a `LazyLayoutCacheWindow` to the composable function. ([I71f19](https://android-review.googlesource.com/#/q/I71f1967bc357f972343311b02169831f747a0cee)) - Removed temporary feature flag `ComposeFoundationFlags.isPausableCompositionInPrefetchEnabled`. ([Ifff7f](https://android-review.googlesource.com/#/q/Ifff7fc0a19fda40684f439b31db09cb0d2e05f34)) - Added `InputTransformation.maxLengthTrim` to limit text length by truncating excess input characters, added `InputTransformation.maxLengthReject` to reject input that exceeds `maxLength`, and deprecated `InputTransformation.maxLength` in favor of `maxLengthTrim` and `maxLengthReject`. ([I8d4cd](https://android-review.googlesource.com/#/q/I8d4cd094b819526966d85a516fe2289f79b2fdbe)) **Bug Fixes** - `compileSdk` for Compose libraries updated to 37.1. This will require transitively updating `compileSdk` for all apps and libraries using Compose. ([I05b0f](https://android-review.googlesource.com/#/q/I05b0f9385d2b99ddcc4041b2ce2d96aea3bd391e)) - Fixed an issue where `WindowInsetsRulers` IME insets were not marked as animating during predictive back, and fixed `imePadding` not updating when switching focus between text fields. ([Id4562](https://android-review.googlesource.com/#/q/Id456204b4bd49644bcbc2304d8e910182b71979d), [b/537386261](https://issuetracker.google.com/issues/537386261), [b/539686000](https://issuetracker.google.com/issues/539686000)) - Updated `SecureTextField` and `OutlinedSecureTextField` components (as well as deprecated `BasicSecureTextField` overloads) to use `TextObfuscationMode.System` as the default obfuscation mode instead of `TextObfuscationMode.RevealLastTyped`. ([I76c7e](https://android-review.googlesource.com/#/q/I76c7ee604ecea755df3c91dfa281778532338f4d)) ### Version 1.13.0-alpha02 August 26, 2026 `androidx.compose.foundation:foundation-*:1.13.0-alpha02` is released. Version 1.13.0-alpha02 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/e9a673661e45bb2eaea8dd43632ce3e1ea6a2094..c3e81656586bd411121465da4b871be2fa24e89c/compose/foundation). **API Changes** - Promoted Grid layout APIs (`Grid`, `GridScope`, `GridConfigurationScope`, `GridFlow`, `Fr`, `GridTrackSize`, `GridTrackSpec`, `Modifier.gridItem`) to stable. ([I43ac4](https://android-review.googlesource.com/#/q/I43ac441e7b6f41d49099db58610657ecb12104ac), [b/462550392](https://issuetracker.google.com/issues/462550392)) - Added new semantics property `BackgroundColor` for Modifier.background ([I7eec3](https://android-review.googlesource.com/#/q/I7eec3e7856bbe392416cb4dbe023a8f3622c1224), [b/518049030](https://issuetracker.google.com/issues/518049030)) - Removed `ExperimentalFlexBoxApi` annotation and renamed pixel-based properties in `FlexConfigScope` with a `Px` suffix for clarity. ([I5b24e](https://android-review.googlesource.com/#/q/I5b24e210dabf09326833dd1bbe96ca5ce18bdf20), [b/543092286](https://issuetracker.google.com/issues/543092286)) - Only keep around cached items when not in a lookahead pass. Introduced flag `isKeepAroundDuringLookaheadDisabled`. To return to the old behaviour set the flag to `false`. ([I110e9](https://android-review.googlesource.com/#/q/I110e9ddcebde92b244ee11d7af426bd3c9165a31)) - Added `isLazyLayoutItemAnimatorVisibleBoundsFixEnabled` compose flag. When enabled, visible item index bounds are calculated before placement animations run in `LazyList` and `LazyGrid` measure. ([I56150](https://android-review.googlesource.com/#/q/I5615036dfe93817912cdd87822973084dff37e99)) - Fix consumption on initial pass in Draggable. This ensures that if a down event is consumed on initial pass, dragging starts immediately in the main pass. This behavior change is gated behind the feature flag `ComposeFoundationFlags`.`isDraggableInitialPassConsumptionFixEnabled`. ([I6a77f](https://android-review.googlesource.com/#/q/I6a77fa35639d31a932f336f77306d67869d50864), [b/532946466](https://issuetracker.google.com/issues/532946466)) ### Version 1.13.0-alpha01 August 12, 2026 `androidx.compose.foundation:foundation-*:1.13.0-alpha01` is released.

Using this modifier now no-ops. Migrate to using `FocusTargetModifierNode.getFocusedRect()` to query this information on demand as needed. ([Ia39db](https://android-review.googlesource.com/#/q/Ia39dbf5b8b6973111dfb3b80c33cc3d84d7dc224), [b/220030968](https://issuetracker.google.com/issues/220030968)) **API Changes** - Providing `LazyLayoutCacheWindow` and `LazyGridPrefetchStrategy` via `LazyGridState` has been deprecated in favour of providing a `LazyLayoutCacheWindow` to the composable function.

Version 1.12.0-alpha03 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/e29a10982f4299b1fa812e229d76792092a62814..8dbbb98c1e39cf64f9d1d51bf26d9347a1a5c447/compose/foundation). **API Changes** - In the experimental Style API, added support for creating custom style types that can have custom style scopes. This allows subsetting the properties settable by a style (such as removing the graphics layer or text properties entirely) as well as allowing the scope to be extended independently of other styles (such as only supporting the `playing { }` syntax in a `MediaPlayer` composable). This change breaks binary and source compatibility. The primary change that breaks source compatibility is that helper functions in the `StyleScope` have moved to be extension functions (e.g. `fun contentProperty(all: Dp)` is now an extension function). Either importing the required extension functions or by importing all symbols from androidx.compose.foundation.styles should be all that is required get code that calls these methods to compile correctly.

If should be on by default. If you find any regressions in the text field layout and disabling this flag fixes it, please file a bug to Compose team to investigate.

This allows developers to explicitly define the minimum bounds of a flexible track. Using `MinMax(0.dp, 1.fr)` successfully bypasses intrinsic measurement queries, making it safe to place `SubcomposeLayout` components like `LazyColumn` and `LazyRow` inside flexible grid tracks without crashing.

Items now correctly share unconsumed shrink space to siblings. Additionally, `FlexBox` will no longer artificially clamp items on main axis; if items cannot shrink enough to fit the container, they will now visually overflow the main axis. Use `Modifier.clipToBounds()` if clipping is desired.

These are controlled by `ComposeFoundationFlags#isBasicTextFieldMinSizeOptimizationEnabled`, should you need to disable them. ([I70ade](https://android-review.googlesource.com/#/q/I70ade2488b5f1add0d22fa359ab5b850a7bfa16f)) - Added `rememberUpdatedStyleState` which is part of the experimental Style API. `rememberUpdated` should be used when createing instances of `StyleState` when parameters of the composable component (such as `enabled`) are copied into the style state ([Idf7ff](https://android-review.googlesource.com/#/q/Idf7ffd2c21f089f112b8d9c17a7d9b64a0bcb85b), [b/485510967](https://issuetracker.google.com/issues/485510967)) - Renames `PointerInputChange` and `HistoricalChange` properties for retrieving scale and pan values.

([I290fb](https://android-review.googlesource.com/#/q/I290fb4dea339278201099d0192a7f617b0aaeed0), [b/473603145](https://issuetracker.google.com/issues/473603145), [b/479213358](https://issuetracker.google.com/issues/479213358)) - Splits the new `PointerEventType.Pan` and into `PointerEventType.PanStart`, `PointerEventType.PanMove` and `PointerEventType.PanEnd`. Similarly, `PointerEventType.Scale` is split into `PointerEventType.ScaleStart`, `PointerEventType.ScaleChange` and `PointerEventType.ScaleEnd`. This split allows passing through additional information about the start and end of platform-interpreted pan and scale gestures, which then allows pointer input handlers in Compose to use this information to detect events appropriately, and especially know when a pan or scale is done. ([I4daf6](https://android-review.googlesource.com/#/q/I4daf682c6cb3624bdbe935115a60fdb9edca19eb), [b/479285849](https://issuetracker.google.com/issues/479285849), [b/481333653](https://issuetracker.google.com/issues/481333653)) - Added `constraints` to `GridConfigurationScope` to allow defining grid tracks based on the available size.

([I8dbae](https://android-review.googlesource.com/#/q/I8dbae079f930c57307ef90970323c31015dca1cc), [b/475491619](https://issuetracker.google.com/issues/475491619)) **Bug Fixes** - Fixed a bug where `OutputTransformation` causes duplicate character insertion on some IMEs. ([I9fdc0](https://android-review.googlesource.com/#/q/I9fdc0a0b7e74197b0141c49bb8750d59d8b956d3)) - Adds fling support to trackpad scrolling gestures ([I55f8a](https://android-review.googlesource.com/#/q/I55f8a17d6c2578003c20f263ae459acfc155406a), [b/479285849](https://issuetracker.google.com/issues/479285849)) - Add benchmarks for the experimental Style API ([I67437](https://android-review.googlesource.com/#/q/I67437ed15c8a32839014cdf2a49b86a9a4f2fa73)) **External Contribution** - Add a `InputTextSuggestionState` property to help identify the different states a transliteration input can be in when text replacement suggestions are available. Also introduces `TextCompositionRange` to track the range of the current transliteration text composition range; a null value indicates no composition in place. ([I7a67f](https://android-review.googlesource.com/#/q/I7a67fc9413c1b856af1c8a41ff25cbc0648c5e97), [b/476472318](https://issuetracker.google.com/issues/476472318)) - Added a new overload to `BasicTooltipBox` that allows configuring `propagateMinConstraints`, similar to Box's parameter with the same name. This allows passing the minimum constraints directly to the children of the `BasicTooltipBox`, without them being relaxed by `BasicTooltipBox`. Thanks Steven Schoen! ([Ib145f](https://android-review.googlesource.com/#/q/Ib145f4c9698cc6aec344235e3e03df494ff02409), [b/467532639](https://issuetracker.google.com/issues/467532639), [b/301605744](https://issuetracker.google.com/issues/301605744)) ### Version 1.11.0-alpha06 February 25, 2026 `androidx.compose.foundation:foundation-*:1.11.0-alpha06` is released. Version 1.11.0-alpha06 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/cdf076c6abd0f3125cb0302756fcb77fe981ab7c..6e23fc0c137022098ae2d043778ffdc56402ba5e/compose/foundation). **API Changes** - Introduces an experimental style API that allows a consistent way to enable customization of composable functions. This API is under active development and may undergo significant changes before becoming stable. See included documentation for details of how to use this API. ([I7fed2](https://android-review.googlesource.com/#/q/I7fed2e5cfceadffce739d5d522171c70aaf678d9), [b/455788242](https://issuetracker.google.com/issues/455788242)) **Bug Fixes** - `Modifier.combinedClickable` is rewritten to not use suspend pointer input as an optimization. This feature is enabled by the flag you can disable if encounter a bug in the new implementation - `ComposeFoundationFlags.isNonSuspendingPointerInputInCombinedClickableEnabled`.([Iea684](https://android-review.googlesource.com/#/q/Iea684f0973b8407920f452b94795ae913ec05f28)) **Known Issues** - The `Modifier.combinedClickable` rewrite introduces a regression for long click behavior that can cause deep presses to trigger repeated long clicks on some devices. This will be fixed in the next release, until then you can set `ComposeFoundationFlags.isNonSuspendingPointerInputInCombinedClickableEnabled=false` to avoid this problem. ### Version 1.11.0-alpha05 February 11, 2026 `androidx.compose.foundation:foundation-*:1.11.0-alpha05` is released. Version 1.11.0-alpha05 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/c26c6f088b95903b7b9cd5e6f2092988f1e64dc3..2e98d140740558dc55710bde96311d2e0e8d5cfd/compose/foundation). **API Changes** - Introduced `isNestedDraggablesTouchConflictFixEnabled` to resolve nested draggable conflicts. We will favor vertical drags over horizontal drags more because UX-wise there's more freedom and uncertainty when a user performs a vertical gesture vs. a horizontal gesture. ([I273c7](https://android-review.googlesource.com/#/q/I273c7a603dcbbd0fe302c7e4589343bbdae26bb9), [b/252334353](https://issuetracker.google.com/issues/252334353), [b/269627294](https://issuetracker.google.com/issues/269627294), [b/363198504](https://issuetracker.google.com/issues/363198504), [b/442390269](https://issuetracker.google.com/issues/442390269), [b/419580124](https://issuetracker.google.com/issues/419580124)) - Adds support for trackpad gestures and conversion from trackpad input events to mouse. With this change, trackpad pointer events that control a cursor like on tablets or laptops will generally be reported as mouse pointers. Pan and scale gestures will also be reported with additional information available in the pointer event changes, with a new `PointerEventType.Pan` and `PointerEventType.Scale` indicating that these values will be set ([Id071a](https://android-review.googlesource.com/#/q/Id071af573d5710d7d3aca73bd1c8037bdb0ea701), [b/315527861](https://issuetracker.google.com/issues/315527861), [b/459831570](https://issuetracker.google.com/issues/459831570)) - Introduce `isDelayPressesUsingGestureConsumptionEnabled`. When this flag is enabled, containers with drag gesture will delay press. This includes a behavior change for containers based off `Modifier.draggable` which didn't delay press previously. ([I53f24](https://android-review.googlesource.com/#/q/I53f242a2161ea4c540e44c615a20581075ac61a6), [b/203141462](https://issuetracker.google.com/issues/203141462)) - Removed the flag `isDetectTapGesturesImmediateCoroutineDispatchEnabled` and deprecated flag `DetectTapGesturesEnableNewDispatchingBehavior` ([I9bba3](https://android-review.googlesource.com/#/q/I9bba3ed7a354147cb6f1cad4f1275a5ec6c1157d)) **Bug Fixes** - Fixed an `IndexOutOfBoundsException` in `BasicTextField` when using \`\`OutputTransformation and deleting text. ([I20ee1](https://android-review.googlesource.com/#/q/I20ee17de095ffb2c598267bd7b1450651d2ce1f1)) - Changed `GridTrackSize.Auto` behavior. It now sizes tracks from `min-content` up to `max-content`.

When settled at an anchor that had the same offset as another anchor, `targetValue` incorrectly returned the last of the anchors at this offset. It now returns the `currentValue` when settled at the `currentValue`'s offset. ([I66a7a](https://android-review.googlesource.com/#/q/I66a7a227dbb1df035eb81d30f9e7b54d502e2d90), [b/476365336](https://issuetracker.google.com/issues/476365336)) - Introduced `FlexBox`, a configurable layout system that is a superset of `Row`, `Column`, `FlowRow`, and `FlowColumn`. It supports features like flex-grow, flex-shrink, custom wrapping, direction change and detailed alignment control via `FlexBoxConfig` and `Modifier.flex`. ([I44780](https://android-review.googlesource.com/#/q/I44780b3c90e0a36f4095ed83e73c9b0984ecd6f6)) - Introduced `Grid`, a new non-lazy 2D layout composable inspired by CSS Grid. This initial version allows defining explicit grid structures with various track sizes including `Fixed`, `Percentage`, `Flex`, and content-based options via the `config` block. The core layout logic supports explicit item placement within the grid using `Modifier.gridItem()`. All Grid related APIs are currently experimental and require opt-in with `@OptIn(ExperimentalGridApi::class)`. We are actively seeking feedback on this new layout!

The `ScrollIndicatorFactory` interface enables creating scroll indicators by defining their appearance and behavior. ([I89322](https://android-review.googlesource.com/#/q/I893224c108519428fe4579fa8d20133462b95d58)) - Removed `ComposeFoundationFlags.isTextFieldDpadNavigationEnabled`.

([I7cbd4](https://android-review.googlesource.com/#/q/I7cbd45779b72807426875ab6efd05e391ed1f111)) - `Modifier.onFirstVisible()` is deprecated as its behavior is misleading and doesn't always follow the contract claimed by the name. For example, when it is added on an item of `LazyColumn`, this callback will be called everytime this item became visible after scrolling. It is not what the users of the modifier with this name might have expected. It is recommended to use `Modifier.onVisibilityChanged()` instead and manually track if the layout was visible already previously based on the requirement of the specific use case.

Please use this interface directly instead of using more generic `LayoutAwareModifierNode` when you don't need other callbacks. ([If6fb0](https://android-review.googlesource.com/#/q/If6fb04b74840d08274d01a41d84bd14507d190b8)) - Introduces a `visible` Modifier which can be used to skip drawing the content of a Composable without affecting the space it occupies.

Now initial prefetching is enabled by default in Pager and prefetching will be based on the size of the window worth 1 viewport, that is, we will try to fill 1 whole view port with prefetched items. Items will be kept around longer as well. ([I4d45e](https://android-review.googlesource.com/#/q/I4d45ece5bab78dc241618d29d3701e5463789aa6), [b/292136289](https://issuetracker.google.com/issues/292136289)) - `ComposeFoundationLayoutFlags.isWindowInsetsOptimizationEnabled` flag has been added to allow disabling a `WindowInsets` performance optimization should the new implementation cause a behavioral change. ([I8e912](https://android-review.googlesource.com/#/q/I8e9129e7cdafc6bc4da61c0b3c0883dbf5376ef5)) - `SnapFlingBehavior` now allows snap animation specs to overshoot during snapping. This allows enables e.g. a bouncy spring spec as the `snapAnimationSpec` to produce a bouncy snap animation. Overshooting values continue to be ignored when performing an approach with the snap spec. ([I373c2](https://android-review.googlesource.com/#/q/I373c2f58fe859a25014c707913041eeb5975f63d)) - Pointer downs with a mouse or touchpad in a `ComposeView` will now clear focus automatically if the pointer down doesn't occur in the bounds of the focused node. This results in a "tap-to-clear focus" UX that is more expected than current behavior when using pointer input devices. This behavior can be opt-ed out of with a new `AbstractComposeView.isClearFocusOnPointerDownEnabled` API. ([I6322b](https://android-review.googlesource.com/#/q/I6322b0a63e80042f6a558104d0684443e5dc161f), [b/282963174](https://issuetracker.google.com/issues/282963174)) - Now Scrollable supports 2 dimensional mouse wheel scroll events better. A new test API landed to help test use cases in `MouseInjectionScope`. We also introduced a new overload for scroll methods in `MouseInjectionScope` and a flag to control the new behavior called `isMouseWheel1DAxisLockingEnabled` ([I136df](https://android-review.googlesource.com/#/q/I136dfe2d0887c1900fb1896599ec4b4aa1b31ac7)) - Updated `DragGestureNode` to use raw pointer input instead of suspending pointer input for optimization. The changes are added behind the flag `isNonSuspendingPointerInputInDraggableEnabled` ([I0fa4b](https://android-review.googlesource.com/#/q/I0fa4b8cedc216b227542f67984796cd02ffc008f)) - Annotated some `AnchoredDraggable` APIs with `@FrequentlyChangingValue`. `offset`, `requireOffset` and `progress` change often and should not be read in composition. Please access these values from the layout and draw phases, effects or otherwise outside of composition instead. ([I05539](https://android-review.googlesource.com/#/q/I0553910e71876e3354ee4f94080d5fecfd8cb032)) - Removed flags `isOnScrollChangedCallbackEnabled`, `isAdjustPointerInputChangeOffsetForVelocityTrackerEnabled`, `isFlingContinuationAtBoundsEnabled`, `isAutomaticNestedPrefetchEnabled`, `DragGesturePickUpEnabled`, `isPointerInteropFilterDispatchingFixEnabled`, `isNestedScrollInteropPostFlingFixEnabled`, `isNestedScrollDispatcherNodeFixEnabled` ([I36c18](https://android-review.googlesource.com/#/q/I36c18840c708660e9cbad345024299bfd80cde3c)) - Introduce `CompositionLocal` that can be used to modify the brush of Autofill's successful filling highlight. ([I52329](https://android-review.googlesource.com/#/q/I52329ea7905c1a0a2db56caa36f4b9d53f3dd0d9)) - Added customizable focus rect to `FocusProperties`. You can now define a custom focus area instead of defaulting the bounding box of the focusable. This information is used by the focus traversal system and the keep in view logic of scrollable containers. ([Id6555](https://android-review.googlesource.com/#/q/Id6555453fe54b4a11db6a6ff90ebaa486b02f395), [b/368378073](https://issuetracker.google.com/issues/368378073)) - Added a new `LineHeightStyle.Mode` called `Tight`. This mode helps enforce smaller line heights even when they may possibly cut taller glyphs. ([Id3849](https://android-review.googlesource.com/#/q/Id38495accc4fe059f6e2318eaafb648f36fe0f99)) - Introduced new Interpolatable interface which allows for automatic interpolation between different types, assuming one type knows how to convert from the other. This interface is leveraged in several compose types like Brush and Shape, but can be utilized externally as well. ([I58eab](https://android-review.googlesource.com/#/q/I58eab524eadd08c41f1809a2815a6311ad179aee)) - Adds indirect input events and a way to specify coordinate axis to use for scrolling. ([I58e7c](https://android-review.googlesource.com/#/q/I58e7c4acc58c38d1690d5267f7f26b7d5cb83d13)) - Adds new `WindowInsets.cutoutPath` API to get the path for the display cutout ([Ib90b1](https://android-review.googlesource.com/#/q/Ib90b14ad65463a23805a44c7531ae2bdbb49f8df), [b/279636456](https://issuetracker.google.com/issues/279636456)) - The `isWindowInsetsDefaultPassThroughEnabled` flag has been removed, defaulting WindowInsets to not consuming so that child Views can receive `WindowInsets` by default. ([I888e0](https://android-review.googlesource.com/#/q/I888e0e284b5f089d19b340258fbe6f2d1f34c7c5), [b/412469666](https://issuetracker.google.com/issues/412469666)) **Bug Fixes** - `isNonSuspendingPointerInputInDraggableEnabled` should be disabled for now. ([Ia41c4](https://android-review.googlesource.com/#/q/Ia41c43344d70a63105a5a10e1d83d86551194e97)) - Moving the default minSdk from API 21 to API 23 ([Ibdfca](https://android-review.googlesource.com/#/q/Ibdfca5942dbb414ca07594ba240093db14aad4df), [b/380448311](https://issuetracker.google.com/issues/380448311), [b/435705964](https://issuetracker.google.com/issues/435705964), [b/435705223](https://issuetracker.google.com/issues/435705223)) - Updated `DraggableAnchors`' `minPosition/maxPosition` documentation to indicate these APIs should return Float.NaN in line with other `DraggableAnchors` APIs. ([I0460a](https://android-review.googlesource.com/#/q/I0460ae646ea59d3fae68fd2f8c27266b1ed7f779)) - Fixed a bug where `DraggableAnchors#closestAnchor` would crash if the anchors were empty ([I4e646](https://android-review.googlesource.com/#/q/I4e646c562b0d2b3538230ec0474c02f296763a72)) - Performance improvements for `DraggableAnchors` ([If4065](https://android-review.googlesource.com/#/q/If40650e0a3b70b8402eaf606f159342c5232c68f), [I0460a](https://android-review.googlesource.com/#/q/I0460ae646ea59d3fae68fd2f8c27266b1ed7f779)) - `TextFieldState.edit { }` no longer clears the undo history. Instead it creates a standalone undo entry. If the desired behavior is to clear the undo stack after an `edit` call, please use `TextFieldState.undoState.clearHistory()`. ([I12c14](https://android-review.googlesource.com/#/q/I12c14696947b577ffb42d33094b89dedb76dc34b)) - Added support for double-tap to select word in `SelectionContainer` and `BasicTextField(value, onValueChange)` overload. ([Ibb06a](https://android-review.googlesource.com/#/q/Ibb06abaa0342a3ccd7483b831f35a2db1b7c27a2)) - Minor bug fix to make `AutoboxingStateValuePropertyDetector` compatible for both K1 and K2 ([Ie81c1](https://android-review.googlesource.com/#/q/Ie81c19fdfb3d88da4b56ae251a3a462dbe927923)) - `requestRectangleOnScreen` requests made by AndroidViews now properly propagates to Compose. This helps views like `EditText` to stay on screen when interacted with. ([Ibbf4c](https://android-review.googlesource.com/#/q/Ibbf4c7255eff71357780058986ded41dbff03c48)) - Column and Row now correctly pass the item's actual size to `Alignment.Vertical.align` and `Alignment.Horizontal.align`, resolving an issue where custom alignment implementations received an incorrect 0 value. ([I3e460](https://android-review.googlesource.com/#/q/I3e460b688b02cce7b1d90ac0949aa185a96a88a3), [b/349722072](https://issuetracker.google.com/issues/349722072)) ## Version 1.9 ### Version 1.9.5 November 19, 2025 `androidx.compose.foundation:foundation-*:1.9.5` is released. Version 1.9.5 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/b7d3ef4c3ddc955decb747a0aa7b72eb953b1e41..1dc35fe3e1d2d1b9dad444a0458c5e8039ba3d26/compose/foundation). ### Version 1.9.4 October 22, 2025 `androidx.compose.foundation:foundation-*:1.9.4` is released.

Version 1.9.1 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/44da9aeaf3fa617c6f81f887691b37fe901109aa..93a1ed2aac05dbfa192392b9d4ab27c40da53d69/compose/foundation). **Bug Fixes** - Fixes crash happening when using `LazyLayoutCacheWindow` in `LazyLists` ([c39f5f3](https://android-review.googlesource.com/#/q/c39f5f3af766384c4517d9e4f684840239b1d5ab)) ### Version 1.9.0 August 13, 2025 `androidx.compose.foundation:foundation-*:1.9.0` is released. Version 1.9.0 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/5735a11c1798c2f8b419dfdc02347578a6ebf870..44da9aeaf3fa617c6f81f887691b37fe901109aa/compose/foundation) **Important changes since 1.8.0** - Lint checks shipped with Compose now require a minimum AGP version of 8.8.2. If you are unable to upgrade AGP, you can instead upgrade Lint on its own by using `android.experimental.lint.version=8.8.2` (or a newer version) in your `gradle.properties`. To run Compose lint checks inside the IDE, Android Studio Ladybug or newer is required. - Breaking change: `clickable`, `combinedClickable`,`selectable`, `toggleable`, and `triStateToggleable` overloads without an Indication parameter now only support `IndicationNodeFactory` instances provided using `LocalIndication`. This change will apply when you recompile your usages of these modifiers using this version of Compose. Binary / transitive dependencies are not affected. If you are providing a deprecated Indication implementation to `LocalIndication`, and using these APIs, this will introduce a crash at runtime. This behavior change is needed to enable improved performance, and allow Composable functions using these modifiers to skip during recomposition. You can use `ComposeFoundationFlags.isNonComposedClickableEnabled=false` to temporarily opt-out of this behavior change, to enable upgrading Compose without being blocked on this migration. This flag will be removed after one stable release. To resolve, migrate any deprecated Indication implementations to use `IndicationNodeFactory` instead. You can also use the overloads with an explicit Indication parameter - these overloads will continue to support non-`IndicationNodeFactory` instances of Indication, although this is not recommended for performance reasons. ([I6bcdc](https://android-review.googlesource.com/#/q/I6bcdc6ff82dd6ff5ea1a97688d5a1426b719df20), [b/316914333](https://issuetracker.google.com/issues/316914333)) - Introduced `isFlingCancellationWithNestedScrollFixEnabled` to fix an issue with fling propagation in nested scrolling. In this CL we are restoring the fling continuation behavior removed in [I9326a](https://android-review.googlesource.com/c/platform/frameworks/support/+/3260391). We will still cancel the fling animation in case the child is removed from composition. ([I467f4](https://android-review.googlesource.com/#/q/I467f4a8974a752d63bd3d6ab62e6eb751f5e2ccc), [b/405910180](https://issuetracker.google.com/issues/405910180), [b/419049142](https://issuetracker.google.com/issues/419049142), [b/416784125](https://issuetracker.google.com/issues/416784125)) - Re-add usage of `scrollAnimationSpec` in `ContentInViewNode`. The behavior was removed during the `scrollAnimationSpec` deprecation which caused use cases to be broken. ([I1436a](https://android-review.googlesource.com/#/q/I1436a3212c8f637935259243253f70db1163e584), [b/403301605](https://issuetracker.google.com/issues/403301605)) - Stabilized `LazyLayout`. ([If5db4](https://android-review.googlesource.com/#/q/If5db4170daec197e39612bcfb5f8b5d4cdd8db52)), `LazyLayoutPrefetchState` and it's scheduling method `schedulePrecomposition` and `schedulePrecompositionAndPremeasure`.

This behavior is introduced under the flag `isOnScrollChangedCallbackEnabled`. We also introduced an extension function of `DelegatableNode dispatchOnScrollChanged`. ([I34b9d](https://android-review.googlesource.com/#/q/I34b9d923ff1fb4a4e27a53e583a7b082bc99b158), [b/238109286](https://issuetracker.google.com/issues/238109286)) - Introduce `Modifier.scrollable2D`, `Scrollable2DState` and companion APIs for state creation. Also introduced common scroll extension functions. ([Ic61c8](https://android-review.googlesource.com/#/q/Ic61c8f14451090f441b009bf8f86e7566c27c782), [b/214410040](https://issuetracker.google.com/issues/214410040)) - `PrefetchScheduler` and customisation have been deprecated in favor of the internal implementation that does all the work automatically. ([I3a9a6](https://android-review.googlesource.com/#/q/I3a9a678918c7ce33174b9c330142a650cc9e3b2a), [b/420551535](https://issuetracker.google.com/issues/420551535)) - `TextFieldState.edit { }` no longer clears the undo history. Instead it creates a standalone undo entry. If the desired behavior is to clear the undo stack after an edit call, please use `TextFieldState.undoState.clearHistory()`. ([I12c14](https://android-review.googlesource.com/#/q/I12c14696947b577ffb42d33094b89dedb76dc34b)) - Context Menu and Selection toolbar now both support Smart Items (Smart Selection) - Added styled text `OutputTransformation` to allow styling the output of `TextField` using the `state` overload. - `TextField`: Support context menu (right click menu). - Text copied from multiple Text composables in a `SelectionContainer` now will have a line separator \\n added between text coming from the separate Text composables. ([I25332](https://android-review.googlesource.com/#/q/I25332168924ca35574bb8c5e7094ad8010ab5927), [b/285036739](https://issuetracker.google.com/issues/285036739)) - Introduce API for creating custom bullet lists through `AnnotatedString` ([I1d066](https://android-review.googlesource.com/#/q/I1d066d3df73999bd3c771b72982fe8bbccc822ae), [b/383269496](https://issuetracker.google.com/issues/383269496), [b/139326648](https://issuetracker.google.com/issues/139326648)) - The `state` overload of `BasicTextField` will keep the cursor scrolled into view when its size changes. ([I0eb41](https://android-review.googlesource.com/#/q/I0eb41276b627d49889d3aedb11b58ba4d2ec0b74), [b/406187741](https://issuetracker.google.com/issues/406187741)) - Breaking change: the `background` and `border` modifier nodes now implement `SemanticsModifierNode`. This can result in new `SemanticsNodes` added to the semantics tree and, therefore, lead to test failures in tests that make assumptions about the semantics tree structure. For example, tests that use `onChild`, `onParent`, `onSibling`, and other similar methods to make assertions can fail if a new node is added between the current and target nodes. The preferred way to fix these failures is to add a `testTag` to the target node directly. Another approach is to use a looser matcher, such as `onNode(hasAnyAncestor(hasText("ancestor")) and hasText("target"))`. ([I638b5](https://android-review.googlesource.com/#/q/I638b56cb3aa3f4f68a354dfa5a42201febee61bc)) ### Version 1.9.0-rc01 July 30, 2025 `androidx.compose.foundation:foundation-*:1.9.0-rc01` is released.

Added `ComposeFoundationFlag.isTextFieldDpadNavigationFixEnabled` to be able to disable this fix for the time being if it causes an undesired behavior in an irrecoverable way. ([Ie1922](https://android-review.googlesource.com/#/q/Ie1922b03e8ec24a0b0d35995e407a3bcd09400a0)) **Bug Fixes** - Fix issue where sticky headers were not sticking if a pinned item was present.

This feature is enabled by a flag - you can disable if you encounter a bug in the new implementation - `ComposeFoundationFlags.isNonSuspendingPointerInputInClickableEnabled`. ([I85b65](https://android-review.googlesource.com/#/q/I85b65452be174df2c548a2c4cf7d96b702596c23)) - Introduced `isFlingCancellationWithNestedScrollFixEnabled` to fix an issue with fling propagation in nested scrolling. In this CL we are restoring the fling continuation behavior removed in [aosp/3260391](https://android-review.googlesource.com/c/platform/frameworks/support/+/3260391). We will still cancel the fling animation in case the child is removed from composition.

Changed `getDisplayCutoutBounds()` to be an extension function of `PlacementScope`. `WindowInsetsAnimationProperties` has been changed to `WindowInsetsAnimation` and the `getAnimationProperties()` has been changed to `getAnimation()`. ([I3816f](https://android-review.googlesource.com/#/q/I3816f062168c83c7bb9e320cfa59a6a4ce1637e8)) - Changed `InsetsRulers` to be in common code with the name `WindowInsetsRulers`. Simplified the API so all insets are `WindowInsetsRulers`. Extracted non-rulers animation properties to an `AnimationProperties` class. `WindowInsetsRulers.innermostOf()` can be used to merge multiple `WindowInsetsRulers`. ([I2f0c6](https://android-review.googlesource.com/#/q/I2f0c6aebeca80fc181e843da78743bf2a5289501), [b/415012444](https://issuetracker.google.com/issues/415012444)) **Bug Fixes** - Re-add usage of `scrollAnimationSpec` in `ContentInViewNode`. The behavior was removed during the `scrollAnimationSpec` deprecation which caused use cases to be broken. ([I1436a](https://android-review.googlesource.com/#/q/I1436a3212c8f637935259243253f70db1163e584), [b/403301605](https://issuetracker.google.com/issues/403301605)) ### Version 1.9.0-alpha04 June 4, 2025 `androidx.compose.foundation:foundation-*:1.9.0-alpha04` is released. Version 1.9.0-alpha04 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/5fd8d5a2f883c1cdd7f712b200d5a4fedf342136..786176dc2284c87a0e620477608e0aca9adeff15/compose/foundation). **API Changes** - `PrefetchScheduler` and customisation have been deprecated in favor of the internal implementation that does all the work automatically. ([I3a9a6](https://android-review.googlesource.com/#/q/I3a9a678918c7ce33174b9c330142a650cc9e3b2a), [b/420551535](https://issuetracker.google.com/issues/420551535)) - Updated `Scrollable2DState` to use an offset in the `canScroll` method instead of an angle. ([I28694](https://android-review.googlesource.com/#/q/I28694cebf0b29b236eea1eaa6e072c7cf7dad623), [b/417268474](https://issuetracker.google.com/issues/417268474)) - Replaced `addAnnotation` in `AnnotatedOutputTransformation` with `addStyle`.

([If5db4](https://android-review.googlesource.com/#/q/If5db4170daec197e39612bcfb5f8b5d4cdd8db52)) - Stabilized an empty constructor for `LazyLayoutPrefetchState` and it's scheduling method `schedulePrecomposition` and `schedulePrecompositionAndPremeasure`. ([I4362f](https://android-review.googlesource.com/#/q/I4362f3417ebe652d967463a474e4ba799967930d), [b/252853717](https://issuetracker.google.com/issues/252853717)) - Introduced `ProcessTextKey` on Android used for context menu items that's added for `PROCESS_TEXT` intent actions. ([If0ac4](https://android-review.googlesource.com/#/q/If0ac40e1a2c4e385de4ebeb0e41afc5f09b00187)) - Make context menu APIs public. Exposed `Modifier.addTextContextMenuComponents` and `Modifier.filterTextContextMenuComponents` to add and remove items in context menu. And also made the following elementary APIs public so that one can build a customized context menu: - `TextContextMenuProvider` - `TextContextMenuDataProvider` - `TextContextMenuData` - `TextContextMenuComponent` - `LocalTextContextMenuDropdownProvider` - `LocalTextContextMenuToolbarProvider` ([I1b7b0](https://android-review.googlesource.com/#/q/I1b7b0fd6744fbae808a3e142cca4ad53bd3731f1)) - Make `LazyLayoutItemProvider` stable ([Icce09](https://android-review.googlesource.com/#/q/Icce09a01e2668ea0a93678ec84d189aa4769e26c), [b/261565751](https://issuetracker.google.com/issues/261565751)) - Introduced android smart selection features that can be enable/disabled via `ComposeFoundationFlags.isSmartSelectionEnabled`. It also exposed a static `compositionLocal` `LocalTextClassifierCoroutineContext` that can be used to specify the `CoroutineContext` in which the `TextClassification` job is launched. ([I1dbaa](https://android-review.googlesource.com/#/q/I1dbaa65e254cc11c1217d2c8ff551c92f7f642f6), [b/139321320](https://issuetracker.google.com/issues/139321320)) ### Version 1.9.0-alpha03 May 20, 2025 `androidx.compose.foundation:foundation-*:1.9.0-alpha03` is released. Version 1.9.0-alpha03 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/b6c541571b9fb5471f965fc52612cb280713e5e4..5fd8d5a2f883c1cdd7f712b200d5a4fedf342136/compose/foundation). **API Changes** - Added `AnnotatedOutputTransformation` that provides a way to add annotations to `TextField` before rendering. ([Ibc6f0](https://android-review.googlesource.com/#/q/Ibc6f08a54bf25e0c6352839df7c2acc6607db482), [b/389978748](https://issuetracker.google.com/issues/389978748)) - Introduce `LazyLayoutMeasurePolicy` and make `LazyLayoutMeasureScope` stable. ([I8c5df](https://android-review.googlesource.com/#/q/I8c5dfa6083fb7d5faf58229556f6b2231386b276), [b/252853717](https://issuetracker.google.com/issues/252853717)) - `BasicSecureTextField` now hoists ScrollState of its internal `BasicTextField`. ([I6e576](https://android-review.googlesource.com/#/q/I6e576357e0fefca548697f83bef17f5e3c3b9648)) - `Modifier.onFirstVisible` and `Modifier.onVisibilityChanged` modifiers were introduced, which are high level modifiers built on top of `Modifier.onLayoutRectChanged`. These modifiers are built specifically to handle a lot of common application requirements such as logging impressions, auto playing videos, etc. These have been built with performance in mind so that they can be used in critical list-based scenarios without risk of sacrificing scroll performance. In addition to these modifier APIs, additional APIs to `RelativeLayoutBounds` have been added in order to support these use cases, as well as make it easier for developers to easily create similar custom modifiers that suit their use case exactly. ([I759b8](https://android-review.googlesource.com/#/q/I759b8256fd7797ad9a10a955368231b70470dd7c)) - Introduced a `detectDragGestures` overload that has touch slop and orientation lock control. ([Iadb0d](https://android-review.googlesource.com/#/q/Iadb0d52c5faf9d37a294f5ea6b529615a0ec8c0e)) - Introduce `Modifier.scrollable2D`, `Scrollable2DState` and companion APIs for state creation. Also introduced common scroll extension functions. ([Ic61c8](https://android-review.googlesource.com/#/q/Ic61c8f14451090f441b009bf8f86e7566c27c782), [b/214410040](https://issuetracker.google.com/issues/214410040)) - Compose 64-bit color values are not directly comparable to Android `ColorLongs` because the color space IDs are out of order for some color spaces. To convert to and from Android color spaces, two new APIs are added: `toColorLong()` and `fromColorLong()`. ([I36899](https://android-review.googlesource.com/#/q/I368990c572cebb2895f87291e9b966ba96b73961)) **Bug Fixes** - Text copied from multiple Text composables in a `SelectionContainer` now will have a line separator `\n` added between text coming from the separate Text composables. ([I25332](https://android-review.googlesource.com/#/q/I25332168924ca35574bb8c5e7094ad8010ab5927), [b/285036739](https://issuetracker.google.com/issues/285036739)) ### Version 1.9.0-alpha02 May 7, 2025 `androidx.compose.foundation:foundation-*:1.9.0-alpha02` is released. Version 1.9.0-alpha02 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/008cbd021e3a2b4d1f36ea7f48200c4692bfc169..b6c541571b9fb5471f965fc52612cb280713e5e4/compose/foundation). **API Changes** - Fixed how pointer input changes are added to the `VelocityTracker` in `DragGestureNode`, this can be controlled with the new flag `isOffsetPositionBeforeAddingToVelocityTrackerEnabled`. ([Ic7992](https://android-review.googlesource.com/#/q/Ic7992d09a4d1bab4e1a4e988afae681d654cf61f), [b/292556787](https://issuetracker.google.com/issues/292556787), [b/236451818](https://issuetracker.google.com/issues/236451818)) - Make `await[Vertical/Horizontal]PointerSlopOrCancellation` public ([I6968b](https://android-review.googlesource.com/#/q/I6968be9620a13a21deb2cd4c3201bc3ca0f72353), [b/298903681](https://issuetracker.google.com/issues/298903681)) - `AbstractComposeView.consumeWindowInsets` now defaults to false. `WindowInsets` will automatically be adjusted for child size and position when set to false, so there is no need to default it to true any longer. This fixes the issue where child Views were not receiving `WindowInsets` updates by default. Developers can opt out of the update either by changing the experimental `ComposeFoundationLayout.isWindowInsetsDefaultPassThroughEnabled` to true or, preferably, by setting `AbstractComposeView.consumeWindowInsets` to true on all Compose view instances. ([I6fa0a](https://android-review.googlesource.com/#/q/I6fa0a74f9b1a25107bebc586f2058bbb598b5eff), [b/411868840](https://issuetracker.google.com/issues/411868840)) **External Contribution** - Fixed Pager crash with extremely large beyondViewportPageCount values ([Idb2db](https://android-review.googlesource.com/#/q/Idb2dbbe5e8d24bb032664c02a3b3fffd6a8d3845)) ### Version 1.9.0-alpha01 April 23, 2025 `androidx.compose.foundation:foundation-*:1.9.0-alpha01` is released. Version 1.9.0-alpha01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/d6d9afca3dfa73c1b9ea74daf9d6ad49c56fe0e9..008cbd021e3a2b4d1f36ea7f48200c4692bfc169/compose/foundation). **Behavior Changes** - Lint checks shipped with Compose now require a minimum AGP version of 8.8.2. If you are unable to upgrade AGP, you can instead upgrade Lint on its own by using `android.experimental.lint.version=8.8.2` (or a newer version) in your `gradle.properties`. To run Compose lint checks inside the IDE, Android Studio Ladybug or newer is required. - Breaking change: `clickable`, `combinedClickable`, `selectable`, `toggleable`, and `triStateToggleable` overloads without an Indication parameter now only support `IndicationNodeFactory` instances provided using `LocalIndication`. This change will apply when you recompile your usages of these modifiers using this version of Compose. Binary / transitive dependencies are not affected. If you are providing a deprecated Indication implementation to `LocalIndication`, and using these APIs, this will introduce a crash at runtime. This behavior change is needed to enable improved performance, and allow Composable functions using these modifiers to skip during recomposition. You can use `ComposeFoundationFlags.isNonComposedClickableEnabled=false` to temporarily opt-out of this behavior change, to enable upgrading Compose without being blocked on this migration. This flag will be removed after one stable release. To resolve, migrate any deprecated Indication implementations to use `IndicationNodeFactory` instead. You can also use the overloads with an explicit Indication parameter - these overloads will continue to support non-`IndicationNodeFactory` instances of Indication, although this is not recommended for performance reasons. ([I6bcdc](https://android-review.googlesource.com/#/q/I6bcdc6ff82dd6ff5ea1a97688d5a1426b719df20), [b/316914333](https://issuetracker.google.com/issues/316914333)) **API Changes** - Introduce API for creating custom bullet lists through `AnnotatedString` ([I1d066](https://android-review.googlesource.com/#/q/I1d066d3df73999bd3c771b72982fe8bbccc822ae), [b/383269496](https://issuetracker.google.com/issues/383269496), [b/139326648](https://issuetracker.google.com/issues/139326648)) - Allow Compose to trigger `ViewTreeObserver.OnScrollChanged`. This behavior is introduced under the flag `isOnScrollChangedCallbackEnabled`. We also introduced an extension function of `DelegatableNode dispatchOnScrollChanged`. ([I34b9d](https://android-review.googlesource.com/#/q/I34b9d923ff1fb4a4e27a53e583a7b082bc99b158), [b/238109286](https://issuetracker.google.com/issues/238109286)) - Projects released with Kotlin 2.0 require KGP 2.0.0 or newer to be consumed ([Idb6b5](https://android-review.googlesource.com/#/q/Idb6b5d6ae1625ab870ffe74f9790ffabc82a63b4)) - Added lint check support for `TextFieldState` to make sure it is remembered inside composition.

([Ibfba6](https://android-review.googlesource.com/#/q/Ibfba6998dc6916bf409d8f4d6b142d715f89c29f)) - Introduced scopes for `schedulePrefetch` calls in grids and lists strategies to align with the `LazyListPrefetchState` capabilities of providing size and index info. ([Iad80c](https://android-review.googlesource.com/#/q/Iad80ca8c87d1d2823f87cb40fc81579c4f6f484c)) - Breaking change: `clickable`, `combinedClickable`, `selectable`, `toggleable`, and `triStateToggleable` overloads without an Indication parameter now only support `IndicationNodeFactory` instances provided using `LocalIndication`.

([Iae46a](https://android-review.googlesource.com/#/q/Iae46a52e7fbb1a3558e897c5afebd125089befbb), [b/395911609](https://issuetracker.google.com/issues/395911609), [b/176949051](https://issuetracker.google.com/issues/176949051)) - Removed deprecated `AutoSize` overloads. Please use the `TextAutoSize` APIs serving the same function. ([I2c90f](https://android-review.googlesource.com/#/q/I2c90f11c8cdfdd3b1f92cf1f401df6a911017693)) - Fixed a caching issue with `TextAutoSize` where a second layout pass with the same constraints could result in using the second-biggest fitting font size instead of the biggest. ([Id367f](https://android-review.googlesource.com/#/q/Id367f4f18e4e0a1bd7c8076a0f956af773dc986b)) ### Version 1.8.0-beta02 February 12, 2025 `androidx.compose.foundation:foundation-*:1.8.0-beta02` is released.

Version 1.8.0-beta01 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/c80a82c4ab50276ac6c1a8d9b9175c9fdbb0d1b8..80c9eca8dc00a6ae7188bf5f2beaf129b79de243/compose/foundation). **API Changes** - `SemanticsNodeInteraction.semanticsId()` has been removed. Use `SemanticsNodeInteraction.fetchSemanticsNode().id` instead. ([Ie397a](https://android-review.googlesource.com/#/q/Ie397a87c7e8bfd754474ebbb03c26f4a3215ba52)) - Rewrite `requestAutofill` API to exist outside of autofill manager. ([Id1929](https://android-review.googlesource.com/#/q/Id1929e5264d1a4a86b937236ee9357529f79fc71)) - `ContextualFlowRow` and `ContextualFlowColumn` have been marked as deprecated. This experimental component was introduced in 1.7 and had not yet been stabilized, and the implementation has been deemed undesirable. In the future, a component solving the use cases this component was meant to solve may be provided. - `FlowRow` and `FlowColumn` have experimental overloads that were introduced in 1.7 that include an `overflow` parameter. The use of this parameter has been deprecated, and the overloads without this parameter can be used instead. The default "overflow" behavior for these overloads will be "Clip", as it was since its introduction. - Many use cases for `ContextualFlowRow` can be accomplished using `FlowRow`, but we acknowledge that is not true in full generality. `ContextualFlowRow` is completely implementable in user-space, and one can attempt to copy its implementation and adapt if desired. In the future, we hope to solve these use cases in a different way. ([Ibafec](https://android-review.googlesource.com/#/q/Ibafec7f7926d2060f7551910264d5dd51637cafc)) **Bug Fixes** - Fix text layout with ellipsis sometimes translating incorrectly during animations, see [b/389707025](https://issuetracker.google.com/issues/389707025) for more info ([Ie55b1](https://android-review.googlesource.com/#/q/Ie55b173dee87596cd270788794b3c0e5e20a0dc6), [b/389707025](https://issuetracker.google.com/issues/389707025)) - Fixed a bug in `BasicText` with `TextAutoSize` and `maxLines` set to 1. ([Ic0450](https://android-review.googlesource.com/#/q/Ic0450c763c5d764492995b44ee1fe570246a9689), [b/376834366](https://issuetracker.google.com/issues/376834366)) - Text's minimum intrinsics height now takes `minLines` parameter into account. It means that minimum intrinsics height reported won't be smaller than the height required to satisfy the `minLines` parameter ([I225f9](https://android-review.googlesource.com/#/q/I225f910dcbff2292d045ffac0750544d4601eeba), [b/388299762](https://issuetracker.google.com/issues/388299762)) ### Version 1.8.0-alpha08 January 15, 2025 `androidx.compose.foundation:foundation-*:1.8.0-alpha08` is released.

See `TextAutoSizeSample` for an example of a custom text auto size implementation. ([I85756](https://android-review.googlesource.com/#/q/I85756591bf459504a338a1e42c18b2d175c4561a)) - Moved the `DetectTapGesturesEnableNewDispatchingBehavior` feature flag to `ComposeFoundationFlags` and renamed it to `isDetectTapGesturesImmediateCoroutineDispatchEnabled`. The old flag is deprecated and will now delegate to `ComposeFoundationFlags.isDetectTapGesturesImmediateCoroutineDispatchEnabled` instead. ([I62932](https://android-review.googlesource.com/#/q/I629321d209cfc727992fbb57db6f82d58e09771a)) **Bug Fixes** - Enabled `DetectTapGesturesEnableNewDispatchingBehavior` by default. `TapGestureDetector` APIs now use the new dispatching behavior (immediate dispatch) by default. ([I9f2bc](https://android-review.googlesource.com/#/q/I9f2bc726cffd87500d10962c067541d8add69b63), [b/369648479](https://issuetracker.google.com/issues/369648479)) - Fixed the `requiredWidth/Height/Size` modifiers to properly handle intrinsic sizes.

([Ifc2e6](https://android-review.googlesource.com/#/q/Ifc2e61bf8dac507072ec7e52a803f40422367c68)) - Added a new Clipboard interface and a composition local for it. ([I80809](https://android-review.googlesource.com/#/q/I808099e232564d551aeeb8ed09e74ab62d9354ed)) ### Version 1.8.0-alpha07 December 11, 2024 `androidx.compose.foundation:foundation-*:1.8.0-alpha07` is released. Version 1.8.0-alpha07 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/6f09cf2ae979e48fdb19485f757a033e4a34bb82..46295bc0b75a16f452e8e0090e8de41073d4dbb6/compose/foundation). **API Changes** - Deleted `ComposeFoundationFlags.RemoveBasicTextGraphicsLayerEnabled` flag that helped revert the removal of internal `graphicsLayer` from `BasicText`. If you were using this flag please let us know of the reasons by filing a bug. Also you can just pass in `Modifier.graphicsLayer()` to your `BasicText` calls to achieve the same behavior as before. ([Id9f90](https://android-review.googlesource.com/#/q/Id9f90910d19dd7bb9e3a43aede83d5bd9188c450)) - Added default implementation for new `stickyHeader` DSL. ([I68986](https://android-review.googlesource.com/#/q/I6898663e2599264a98e6ce2537ef9f0e065db571)) - Has `LocalAutofillHighlightColor` composition local use a Color type. ([I0e05b](https://android-review.googlesource.com/#/q/I0e05bc47c50ff04a873169ab69dfc79f9ecc0579)) - Renamed `OverscrollEffect#withoutDrawing` to `OverscrollEffect#withoutVisualEffect`. ([I1a154](https://android-review.googlesource.com/#/q/I1a154f66a48cea170b6f1de3b98aaf451fb1f111)) **Bug Fixes** - Follow-up fix for an issue in `AnchoredDraggable`'s target calculation where it could settle at the wrong anchor for specific swipes. ([I23b87](https://android-review.googlesource.com/#/q/I23b8773d3a694aa3c8de6a8f34b9d7fb54cfe560), [b/367660226](https://issuetracker.google.com/issues/367660226)) **External Contribution** - Add `BringIntoViewResponderModifierNode` to UI, which provides a new way to implement Bring Into View functionality as well as allows implementing in on a platform level ([Ia6dd8](https://android-review.googlesource.com/#/q/Ia6dd89b79c7a4e04fea0d73410b2b76e779b793f)) - We are ever slightly changing the way the cursor is drawn. You can use `LocalCursorBlinkEnabled` to disable the cursor drawing in tests. ([I4c697](https://android-review.googlesource.com/#/q/I4c6979903bec329287ec25093f55b83668d674ea)) ### Version 1.8.0-alpha06 November 13, 2024 `androidx.compose.foundation:foundation-*:1.8.0-alpha06` is released. Version 1.8.0-alpha06 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/ccd90a76bd7c4acf4f4f01eca76350e383bc441e..6f09cf2ae979e48fdb19485f757a033e4a34bb82/compose/foundation). **API Changes** - Adds `stylusHoverIcon` modifier. ([Iff20a](https://android-review.googlesource.com/#/q/Iff20af03b451228bc44c4356d4b4e89956cc3b45), [b/331289114](https://issuetracker.google.com/issues/331289114)) - Deprecated `AnchoredDraggableState`'s `confirmValueChange`. Instead of vetoing state changes, disallowed anchors should not be in the active anchor set, and an `OverscrollEffect` should be used to indicate the unavailability of the requested action. ([Ia717f](https://android-review.googlesource.com/#/q/Ia717fb7dba3db65609a933a55b164d2186e25806)) - Changes Autofill manager to be an interface. ([I84914](https://android-review.googlesource.com/#/q/I8491407de5699bf7273b9f88bda11cc438e2fd62), [b/376080755](https://issuetracker.google.com/issues/376080755)) - Adds `OverscrollEffect#withoutDrawing` and `OverscrollEffect#withoutEventHandling` APIs - these APIs create a wrapped instance of the provided overscroll effect that doesn't draw / handle events respectively, which allows for rendering overscroll in a separate component from the component that is dispatching events. For example, disabling drawing the overscroll inside a lazy list, and then drawing the overscroll separately on top / elsewhere. ([Idbb3d](https://android-review.googlesource.com/#/q/Idbb3d91546b49c1987a041f959bce4b2b09a9f61), [b/266550551](https://issuetracker.google.com/issues/266550551), [b/204650733](https://issuetracker.google.com/issues/204650733), [b/255554340](https://issuetracker.google.com/issues/255554340), [b/229537244](https://issuetracker.google.com/issues/229537244)) - Adding autofill support in text toolbar. ([Ie6a4c](https://android-review.googlesource.com/#/q/Ie6a4c0542737d76d603a925f85c389c81eb49747)) - Deprecates `OverscrollConfiguration` and `LocalOverscrollConfiguration`, and adds `rememberPlatformOverscrollFactory` to create an instance of / customize parameters of the default overscroll implementation. To disable overscroll, instead of `LocalOverscrollConfiguration provides null`, use `LocalOverscrollFactory provides null`. To change the glow color / padding, instead of `LocalOverscrollConfiguration provides OverscrollConfiguration(myColor, myPadding)`, use `LocalOverscrollFactory provides rememberPlatformOverscrollFactory(myColor, myPadding)`. ([Ie71f9](https://android-review.googlesource.com/#/q/Ie71f9a016face13262f4fe16ac56c40a0d6f9712), [b/255554340](https://issuetracker.google.com/issues/255554340), [b/234451516](https://issuetracker.google.com/issues/234451516)) - Changed the `effectModifier` property on `OverscrollEffect` to be `node: DelegatableNode`, consistent with other APIs. ([Ic0b46](https://android-review.googlesource.com/#/q/Ic0b46a80aa7d9426ced0731531b3492093e1654e), [b/255554340](https://issuetracker.google.com/issues/255554340)) - Removed the experimental `GlobalAssertions` API. It's intended use was to run accessibility checks, see `enableAccessibilityChecks()` for that purpose instead. ([I59322](https://android-review.googlesource.com/#/q/I5932296f2aca4c3daa30a013dd00e876ecebb077)) ### Version 1.8.0-alpha05 October 30, 2024 `androidx.compose.foundation:foundation-*:1.8.0-alpha05` is released. Version 1.8.0-alpha05 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/b8a68b0896897fa158508d73a31998a26161d9a7..ccd90a76bd7c4acf4f4f01eca76350e383bc441e/compose/foundation). **New Features** - Support for auto-sizing text. Pass an `AutoSize` instance (e.g. `AutoSize.StepBased`) to your favorite text composable (like `BasicText`) and see your text size adapt to the available space! ([Ice7e0](https://android-review.googlesource.com/#/q/Ice7e09b9cac7be10ab5e681ec57d994d50102583), [b/139320827](https://issuetracker.google.com/issues/139320827)) - Adds `OverscrollFactory` and `LocalOverscrollFactory` APIs to allow configuring overscroll within a hierarchy. The value provided through `LocalOverscrollFactory` will be used by default to create an `OverscrollEffect`. To create and remember an effect from the current provided factory, use `rememberOverscrollEffect()`. ([I51ca4](https://android-review.googlesource.com/#/q/I51ca476f3efcf0249640873f74cf7d40beebb788), [b/255554340](https://issuetracker.google.com/issues/255554340)) **API Changes** - Introduce `CompositionLocal` that can be used to modify the hue of Autofill's successful filling highlight. ([I32092](https://android-review.googlesource.com/#/q/I320926246d1811c2c974a6793f48941907c33afe)) - Removed `ScrollableDefaults.overscrollEffect` - instead you should use `rememberOverscrollEffect`. This will create an instance of the current overscroll implementation provided with `LocalOverscrollFactory`. ([I1651a](https://android-review.googlesource.com/#/q/I1651acbab8ddb4b35399af103e3db76b37361303), [b/255554340](https://issuetracker.google.com/issues/255554340)),([b/234451516](https://issuetracker.google.com/issues/234451516)) - Introduces new `AutofillManager` interface that can be used to fine-tune users' Autofill journey and a `isSemanticAutofillEnabled` flag to turn on this new version of Autofill. ([I9d484](https://android-review.googlesource.com/#/q/I9d4842cc35b289158e889f89b7b65346f049e884)) - Removes `CombinedClickableNode`. This experimental API was temporarily exposed to unblock performance work, but is no longer needed. Instead you should directly use `Modifier.combinedClickable` as with other modifier APIs. ([I4b658](https://android-review.googlesource.com/#/q/I4b658dabfefb13eb5bff42029502486ab89b7a6f)) - Adds overloads to `horizontalScroll`, `verticalScroll`, `LazyColumn`, `LazyRow`, `LazyHorizontalGrid`, `LazyVerticalGrid`, `LazyHorizontalStaggeredGrid`, `LazyVerticalStaggeredGrid`, `HorizontalPager`, and `VerticalPager` with support for specifying a custom `OverscrollEffect`. The provided `OverscrollEffect` will receive events, and be rendered within the bounds of these components. Note that drawing the same `OverscrollEffect` twice is unsupported - so you cannot draw the same `OverscrollEffect` provided to one of these components separately with `Modifier.overscroll`. The use case of drawing the overscroll outside of the bounds of these components will be addressed separately in the future. ([I2dc42](https://android-review.googlesource.com/#/q/I2dc42851c824a63e495312246eb5389c33121af8), [b/266550551](https://issuetracker.google.com/issues/266550551), [b/234274772](https://issuetracker.google.com/issues/234274772), [b/224572538](https://issuetracker.google.com/issues/224572538), [b/353805117](https://issuetracker.google.com/issues/353805117)) ### Version 1.8.0-alpha04 October 16, 2024 `androidx.compose.foundation:foundation-*:1.8.0-alpha04` is released.

([I04f3e](https://android-review.googlesource.com/#/q/I04f3e3afea5aabdc6225b1afb197df18133eb018), [b/340662451](https://issuetracker.google.com/issues/340662451)) - Paragraph and `ParagraphIntrinsics` now takes a list of all annotations applied to the `AnnotatedString`, previously it only had a list of `SpanStyles`. ([I12f80](https://android-review.googlesource.com/#/q/I12f8071e3bb8ed7871bb659e256569182680d49e)) - Introduced `PointerInputModifierNode#touchBoundsExpansion`, which can be used to enlarge the touch bounds of a single pointer input modifier. ([Iccf02](https://android-review.googlesource.com/#/q/Iccf028b886639d3b24e7a257a023320362399389), [b/335339283](https://issuetracker.google.com/issues/335339283)) **Bug Fixes** - Fixed a bug where positional thresholds passed to `AnchoredDraggableDefaults.flingBehavior` were not considered correctly in some scenarios. ([Ifdf0d](https://android-review.googlesource.com/#/q/Ifdf0dfcf3d7ff8288affee56e7092bbed473d6ab), [b/367660226](https://issuetracker.google.com/issues/367660226)) - Introduce a fix for nested scrollables that are removed from the node tree during an ongoing fling. Now these nodes will cancel the fling and correctly send the `onPostFling` event with the remaining velocity. We're also introducing the flag `NewNestedScrollFlingDispatchingEnabled` to control the behavior in case of regressions. The flag will be removed before beta. ([I05c37](https://android-review.googlesource.com/#/q/I05c37b5d0ae42d8ed97c014383fe9df3282d61d6), [b/371168883](https://issuetracker.google.com/issues/371168883)) - Fixed a bug where `OverscrollEffects` passed to `Modifier.anchoredDraggable` would receive 2D deltas instead of 1D. ([Ie52c0](https://android-review.googlesource.com/#/q/Ie52c0db5e85eef359cf82b2f88713a31cf6802f4)) ### Version 1.8.0-alpha03 October 2, 2024 `androidx.compose.foundation:foundation-*:1.8.0-alpha03` is released.

([Id354b](https://android-review.googlesource.com/#/q/Id354b132da03348aaa68da0dd8459d4528438018), [b/354109776](https://issuetracker.google.com/issues/354109776), [b/239672673](https://issuetracker.google.com/issues/239672673)) - Removed the implicit `graphicsLayer` modifier from `BasicText` composable. Added experimental `ComposeFoundationFlags.RemoveBasicTextGraphicsLayerEnabled` flag to be able to revert to the old behavior. ([Ie478d](https://android-review.googlesource.com/#/q/Ie478db03fec7f5a7ee48b46e03a63c4b718fe69c)) - Added `Modifier.recalculateWindowInsets()` to allow children in the hierarchy to use `insetsPadding` even when parents aligned them without `consumeWindowInsets()`. ([I7f9e4](https://android-review.googlesource.com/#/q/I7f9e42ad23eb6a8706ab9c04dc60460b3e91695d)) **Bug Fixes** - Implement gesture pick-up in `detectDragGestures`, draggables and scrollables. Now if a child draggable gives up on a gesture, the parent has the opportunity to pick it up. This allows for a more continuous and integrated gesture handling. ([Ic88fe](https://android-review.googlesource.com/#/q/Ic88fe7a8d34eb49ae279b922ef570a3464924727)) - Update fling cancellation behavior in scrollables.

None of these targets are meant to be used, they are placeholders to help Jetbrains Compose efforts. ### Version 1.7.0 September 4, 2024 `androidx.compose.foundation:foundation-*:1.7.0` is released. Version 1.7.0 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/d8995e2377dd4baad64b39becb6d480cadd05c86..38ffb9c315c3f894412184bda180c1b58b2a8556/compose/foundation). **Important changes since 1.6.0** - Performance of `Modifier.clickable`, `Modifier.focusable`, `Modifier.indication`, `Modifier.scrollable` and `Modifier.draggable` has been significantly improved. As a part of this effort, the following API changes were made in addition to internal changes - Added a new Indication API, `IndicationNodeFactory`. This leads to more performant Indication implementations compared to the previous (now deprecated) `rememberUpdatedInstance` API. For migration information, see [developer.android.com](http://developer.android.com/). - `clickable` / `combinedClickable` / `selectable` / `toggleable` now accepts a nullable `MutableInteractionSource` parameter. If null, and the provided Indication is an `IndicationNodeFactory`, the Indication can be lazily created only when needed, which improves performance. If you are not hoisting and using the `MutableInteractionSource`, it is recommended to pass null instead of passing `remember { MutableInteractionSource() }`. - `Indication#rememberUpdatedInstance` has been deprecated. It has a high unavoidable performance penalty, and prevents other optimizations. Instead, you should use the new `IndicationNodeFactory` API. - `BasicTextField` using a [`TextFieldState`](https://developer.android.com/reference/kotlin/androidx/compose/foundation/text/input/TextFieldState) is now stable and we advise all call-sites to begin migration from `BasicTextField(value, onValueChange)` to `BasicTextField(TextFieldState)`. - The `ClickableText` has been deprecated. To add clickable links to your text, use `BasicText` with the new [`LinkAnnotation`](https://developer.android.com/reference/kotlin/androidx/compose/ui/text/LinkAnnotation) annotation in your `AnnotatedString`. `LinkAnnotation` allows for custom styling based on link state (e.g. focused, hovered). - Introducing `ContextualFlowRow` and `Enhanced FlowRow/Column` with `MaxLines` and `Overflow`. We are excited to announce enhancements to the experimental `FlowRow` and `FlowColumn`, now featuring `maxLines` and overflow support, alongside the debut of `ContextualFlowRow` and `ContextualFlowColumn`. This update is designed to provide performance optimal components, where `ContextualFlow*` is perfect for a large number of items making use of a small maxLines config and dynamic +N see more buttons, and `FlowRow` and `FlowColumn` is perfect for a small number of items, less than 100 items. Important: To maintain existing behavior in `FlowRow` or `FlowColumn` where all items are composed regardless of if they fit the cross axis max, set overflow to `FlowRowOverflow.Visible` or `FlowColumnOverflow.Visible` during initialization. Explore `ContextualFlowRowSample` and `FlowRowSample` for examples of these new features in action. ([Ib9135](https://android-review.googlesource.com/#/q/Ib913509969a79ff002eafb0075e6722a7a118531), [b/293577082](https://issuetracker.google.com/issues/293577082)) - Item appearance and disappearance animation support was added into `LazyColumn` and `LazyRow`. Previously it was possible to add `Modifier.animateItemPlacement()` modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called `Modifier.animateItem()` which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. ([I2d7f7](https://android-review.googlesource.com/#/q/I2d7f7a376cea26c0a36a59a4586d2705ab04cab7), [b/150812265](https://issuetracker.google.com/issues/150812265)) - Implemented experimental support for long screenshots in Compose scroll containers using the official Android API (`ScrollCaptureCallback`). - `NestedScroll` sources Drag and Fling are being replaced by `UserInput` and `SideEffect` to accommodate for the extended definition of these sources that now include animations (Side Effect) and Mouse Wheel and Keyboard (`UserInput`). - `LazyLayout` prefetch requests can be marked as urgent now, meaning that we expect this item to be needed in the next frame and want to ignore frame budget to make sure to do more work in advance ([Id513f](https://android-review.googlesource.com/#/q/Id513f17517aa1b240e91afb3468837b12ed54da8)) - Support stylus handwriting feature on devices after Android U.

This includes support for prefetching items in nested `LazyGrids`. Similiar to `LazyListPrefetchStrategy`, the implementation default is to prefetch the first 2 nested items of each grid, but this can be configured by the new `LazyGridPrefetchStrategy(nestedPrefetchItemCount)` and `LazyListPrefetchStrategy#onNestedPrefetch` APIs.

([Ib9154](https://android-review.googlesource.com/#/q/Ib915439b1f029adfcfff0ee716b1ad5759f4a35d)) - Added support for prefetching items in nested `LazyLists` (e.g. a `LazyColumn` that renders nested `LazyRows`). This change is expected to reduce frame drops during scrolling for these `LazyLists`. The implementation default is to prefetch the first 2 nested items, however this behavior can be controlled by the new `LazyLayoutPrefetchStrategy(nestedPrefetchItemCount)` and `LazyListPrefetchStrategy#onNestedPrefetch` APIs. ([I51952](https://android-review.googlesource.com/#/q/I519526a694d8e9a89a1a040cd179d0416fa2d6d9)) ### Version 1.7.0-alpha07 April 17, 2024 `androidx.compose.foundation:foundation-*:1.7.0-alpha07` is released. Version 1.7.0-alpha07 contains [these commits](https://android.googlesource.com/platform/frameworks/support/+log/02b55f664eba38e42e362e1af3913be1df552d55..67004410fdbff19f90caa4cc43965ab21dca1943/compose/foundation). **New Features** - Added a `TextDefaults` object that contains methods to construct a `LinkAnnotation` and parse HTML-tagged string which apply `MaterialTheme` to the links. ([I98532](https://android-review.googlesource.com/#/q/I98532f3512d1930416f66dd195746eeeba884497), [b/139312671](https://issuetracker.google.com/issues/139312671)) - Item appearance and disappearance animation support was added into`LazyVerticalGrid` and `LazyHorizontalGrid`. Previously it was possible to add `Modifier.animateItemPlacement()` modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called `Modifier.animateItem()` which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering. ([Ib7d12](https://android-review.googlesource.com/#/q/Ib7d120e5dfec53dae00dc662e982dafeab1a6b0f), [b/330510929](https://issuetracker.google.com/issues/330510929)) - Item appearance and disappearance animation support was added into `LazyVerticalStaggeredGrid` and `LazyHorizontalStaggeredGrid`. Previously it was possible to add `Modifier.animateItemPlacement()` modifier in order to support placement (reordering) animations. We deprecated this modifier and introduced a new non-experimental modifier called `Modifier.animateItem()` which allows you to support all three animation types: appearance (fade in), disappearance (fade out) and reordering.

The colors of the context menu on text fields and selectable text can be modified by providing the composition local. ([Ifa154](https://android-review.googlesource.com/#/q/Ifa154a761c372822bca1182023b70cb82b2a14b9)) - Text links got pressed state styling option in addition to normal styling, hovered and focused. ([I5f864](https://android-review.googlesource.com/#/q/I5f864b3fd1b1af6ff39dee03e1aa65ede7e16d32), [b/139312671](https://issuetracker.google.com/issues/139312671)) - Introduce `ViewConfiguration.HandwritingGestureLineMargin` for handwriting gestures. Support handwriting gesture for `BasicTextField`. ([Ie6e13](https://android-review.googlesource.com/#/q/Ie6e13b41cc82da1fd3c9ecc7ac34c3ff88dfa235), [b/325660505](https://issuetracker.google.com/issues/325660505)) - Removed `DelegatableNode.scrollIntoView` for the 1.7 release since we didn't have time to finish stabilizing the rest of the related API surface. This function will be re-introduced in 1.8 ([I6cf61](https://android-review.googlesource.com/#/q/I6cf6120f4cb0b4fbb4fbaff7bf57793b854da202), [b/333421581](https://issuetracker.google.com/issues/333421581), [b/332900232](https://issuetracker.google.com/issues/332900232)) - When querying Layout coordinates, you may now use the `excludeDirectManipulationOffset` argument to exclude the offset set by parent Layouts that placed their children using `Placeable.PlacementScope.withDirectManipulationPlacement`. Likewise, a Layout that changes the position of its children frequently may now place them using `withDirectManipulationPlacement` (such as Scroll, implemented by default). This helps `approachLayout` based animations to be more intuitive, having now the opportunity to differentiate what offset to animate, and what to apply directly when deciding to animate their approach. ([I60ec7](https://android-review.googlesource.com/#/q/I60ec77cec9d448ffdfed8b661ba2e433f3adaa55)) - Introduce `requestScrollToItem` for `LazyStaggeredGrid`. For each measure-pass, the client may now opt-out of maintaining index based on the key by calling `requestScrollToItem`. This does not change existing behavior in any way unless `requestScrollToItem` is called.

([I0a7a0](https://android-review.googlesource.com/#/q/I0a7a06d25850d4ff11b782568bc42e6724b3c862)) - `ClickableText` is marked as deprecated. To add links to the text, create an `AnnotatedString` with a `LinkAnnotation` corresponding to your link and pass this `AnnotatedString` to the `Text` composable ([I34d4b](https://android-review.googlesource.com/#/q/I34d4bf29a9386820f8582765e62576a5fcfcd3c6), [b/323346994](https://issuetracker.google.com/issues/323346994)) - `UrlAnnotation` is deprecated, use `LinkAnnotation.Url` instead. If you're using Material theming, then use `TextDefaults` object to create the annotation with Material theming applied to it ([I8d180](https://android-review.googlesource.com/#/q/I8d18033220b74bb84f74380855ef5efb5e3e92bb), [b/323346545](https://issuetracker.google.com/issues/323346545)) - `String.parseAsHtml` renamed to `AnnotatedString.Companion.fromHtml` ([I43dcd](https://android-review.googlesource.com/#/q/I43dcd5b6f6ddc634879f5747df4b911953f84632)) - Added styling arguments (`linkStyle`, `focusedLinkStyle`, `hoveredLinkStyle`) and a link interaction listener to the `parseAsHtml` method. When parsing the HTML-tagged string with `` tags, the method will construct a `LinkAnnotation.Url` for each such tag and pass the styling objects and link interaction listener to each annotation. ([I7c977](https://android-review.googlesource.com/#/q/I7c9777a340e04ccf4dc10258c83d18e69831b3c6)) - `LinkAnnotation` now takes the state-based styling arguments and a `LinkInteractionListener`. Add this annotation to the `AnnotatedString` to get a hyperlink. By passing `focusedState` and/or `hoveredState` you can define the visual configuration for links when they are focused and/or hovered. ([I81ce4](https://android-review.googlesource.com/#/q/I81ce4350b8a1e37881000fd82f081b7afb8e0f42), [b/139312671](https://issuetracker.google.com/issues/139312671)) - The feature flag for long screenshots has been removed.

Note that not all tags are supported, for example you won't be able to display bullet lists yet. ([I84d3d](https://android-review.googlesource.com/#/q/I84d3d1881805e964cea940eb1c68a5bba16f6416)) - Implemented experimental support for long screenshots in Compose scroll containers using the official Android API (`ScrollCaptureCallback`). This feature is experimental and may not currently handle all cases correctly. For that reason it is currently disabled by default. To opt-in, set the `ComposeFeatureFlag_LongScreenshotsEnabled` flag to true. This flag will be removed before 1.7 beta. ([I2b055](https://android-review.googlesource.com/#/q/I2b0552d34c530b127d64ac58f48a0fa399b3edde), [b/329296471](https://issuetracker.google.com/issues/329296471)) - Introduce new `GraphicsLayer` API to provide more flexibility in placement and rendering of `GraphicsLayer` instances and support intrinsic rendering features without needing to coordinate with Composable implementations to specify `GraphicsLayer` modifier instances. **API Changes** - All `KeyboardOptions` parameters now have an unspecified value by default.

We are excited to announce enhancements to the experimental `FlowRow` and `FlowColumn`, now featuring `maxLines` and overflow support, alongside the debut of `ContextualFlowRow` and `ContextualFlowColumn`. This update is designed to provide performance optimal components, where `ContextualFlow*` is perfect for a large number of items making use of a small `maxLines` config and dynamic +N see more buttons, and `FlowRow` and `FlowColumn` is perfect for a small number of items, less than 100 items. Important: To maintain existing behavior in `FlowRow` or `FlowColumn` where all items are composed regardless of if they fit the cross axis max, set `overflow` to `FlowRowOverflow.Visible` or `FlowColumnOverflow.Visible` during initialization.

When using Material theme the color of the link by default will be set to Material's primary color. ([I7eb10](https://android-review.googlesource.com/#/q/I7eb10b55fcec1b268c60744de700058eb11a385a)) - Introduced `receiveContent` modifier that provides developers with a way to [receive rich content](https://developer.android.com/develop/ui/views/receive-rich-content) in Jetpack Compose. - `receiveContent` integrates with `BasicTextField2` to accept rich content provided by the software keyboard, or via Clipboard paste action.

[Version 1.7.0-alpha01 contains these commits.](https://android.googlesource.com/platform/frameworks/support/+log/2b3fea6e026942389e9db59a4d68f2bb32c94e8f/compose/foundation) **New Features** - Added a new `Indication API`, `IndicationNodeFactory`. This leads to more performant `Indication` implementations compared to the previous (now deprecated) `rememberUpdatedInstance` API. For migration information, see [developer.android.com](http://developer.android.com). - `clickable / combinedClickable / selectable / toggleable` now accepts a nullable `MutableInteractionSource` parameter. If null, and the provided `Indication` is an `IndicationNodeFactory`, the `Indication` can be lazily created only when needed, which improves performance. If you are not hoisting and using the `MutableInteractionSource`, it is recommended to pass null. **API Changes** - Introduce `DecayAnimation` in `AnchoredDraggable`, this change adds a `decayAnimationSpec` parameter to `AnchoredDraggable` allowing to use decay animation when settling to one of the anchors. The change also includes renaming the existing `animationSpec` to `snapAnimationSpec` to help understanding the use case of each spec. - `BasicTextField2` is available for experimental use. It should be roughly at feature parity with `BasicTextField`, and behavior should be production-ready. However, the API remains experimental for now. Before stabilizing, it will be renamed to `BasicTextField` and moved into the same package. - Introduced the first draft of the `OutputTransformation` API for `BasicTextField2`. This API replaces most of the use cases of `VisualTransformation` in the old `BasicTextField`. However it is not complete yet, and some things won't work correctly, but we'd appreciate any feedback on the API usability for your use cases. ([aosp/2708848](https://r.android.com/2708848)) - Introduced `LinkAnnotation` that allows to add links and clickables into text. Links feature is not complete yet and more API changes are coming. - Introduced `receiveContent` modifier that provides developers with a way to [receive rich content](https://developer.android.com/develop/ui/views/receive-rich-content) in Jetpack Compose. - `receiveContent` integrates with `BasicTextField2` to accept rich content provided by the software keyboard, or via paste from Clipboard. - `KeyboardOptions.shouldShowKeyboardOnFocus` allows you to disable the default behavior of `BasicTextField` of requesting a software keyboard on focus. - `TextInputService` and `LocalTextInputService` are now deprecated. Use `PlatformTextInputModifierNode` to integrate directly with platform IME APIs instead. ([aosp/2862698](https://r.android.com/2862698)) - `Indication#rememberUpdatedInstance` has been deprecated. It has a high unavoidable performance penalty, and prevents other optimizations. Instead, you should use the new `IndicationNodeFactory` API. **Bug Fixes** - `BasicTextField` will now pre-validate a small selection of offset mappings when `VisualTransformation` is passed. This helps catch common coding errors that lead to unrecoverable exceptions in later measure or draw passes. By throwing during composition, it is more likely developers will see these errors during development helping avoid production crashes. ([I0fd42](https://android.googlesource.com/c/platform/frameworks/support/+/290461)) - `VisualTransformation` will not throw if you return an invalid index for an invalid index ([b/316401857](http://b/316401857)) ## Version 1.6 ### Version 1.6.8 June 12, 2024 `androidx.compose.foundation:foundation-*:1.6.8` is released.

([Icd27d](https://android-review.googlesource.com/#/q/Icd27ddc109548e76c7bc4fba08fb9dfc174afa40)) **Bug Fixes** - Adjustments in the snapping physics in `SnapFlingBehaviour` for a more natural feel. **Known Issue** - When updating from `androidx.compose.foundation:1.4.0-alpha03` to `androidx.compose.foundation:1.4.0-alpha04`, you might experience a `java.lang.NoSuchFieldError` error. [Here](https://issuetracker.google.com/issues/265172081) is where the issue was orginially reported. A fix has been submitted, and will be available on the next Compose update. As a work around, update your `androidx.compose.material` and `androidx.compose.material3` libraries to the latest version(1.1.0-alpha04) or downgrade your `androidx.compose.foundation` to 1.4.0-alpha03. ### Version 1.4.0-alpha03 December 7, 2022 `androidx.compose.foundation:foundation:1.4.0-alpha03` and `androidx.compose.foundation:foundation-layout:1.4.0-alpha03` are released. [Version 1.4.0-alpha03 contains these commits.](https://android.googlesource.com/platform/frameworks/support/+log/a1e318590b217ecfce1b2de17eed2f18b6a680bb..047e199bdcb8a5cd744cc7a2f986631bfb350ec7/compose/foundation) **API Changes** - In UI tests using a Compose rule, continuations resumed during `withFrameNanos` callbacks will not be dispatched until after all frame callbacks have finished running. This matches the behavior of compose when running normally. However, tests that rely on the old behavior may fail. This should only affect code that calls `withFrameNanos` or `withFrameMillis` directly, and has logic outside of callback passed to those functions that may need to be moved inside the callbacks. See the animation test changes in [this CL for examples](https://android-review.googlesource.com/#/q/Idb41309445a030c91e8e4ae05daa9642b450505c). - Added optional `onPerformTraversals: (Long) -> Unit` parameter to `TestMonotonicFrameClock` constructor and factory function to run code after `withFrameNanos` callbacks but before resuming callers' coroutines.

Note that these are only available from API 29. ([Ida4ab](https://android-review.googlesource.com/#/q/Ida4ab069a2c7f8d2fc06bf20555c611f4a360728)) - Introduce `HorizontalPager` and `VerticalPager`, a way of showing composables in a Pager manner. Introduced `PagerState` to control the Pagers as well as query information about the Pager's current state. Introduced `PageSize`, a way of controlling the size of a Pager's page, this can be used to create a carousel like Pagers. Introduced `PagerSnapDistance`, a way to control how snapping will work in Pager's fling behavior. ([I01120](https://android-review.googlesource.com/#/q/I01120224eaccd9ee255890eb409e87a7ef7ffd5f)) - Introduced an overload in `SnapFlingBehavior.performFling` to help to understand where the fling will settle.

Instead of needing to remember and set this flag, just don't dispatch events to the overscroll effect in cases where you do not want overscroll to show (for example if `ScrollableState#canScrollForward/backward` both return false).

This defaults to true for backwards compatibility with existing implementations of `ScrollableState`. Consumers can use this to show indication to the user that there is still room to scroll, and this could also be used to avoid dispatching delta to `ScrollableStates` that have no room to scroll in a given direction, to reduce unnecessary work.

It allows to represent some list of values via multiple intervals. It will be useful when you want to define your own dsl similar to the one used by `LazyColumn` where list items can be defined via multiple item/items calls. ([I2d05e](https://android-review.googlesource.com/#/q/I2d05e91646068eab522514024b483d88d77be309), [b/228580728](https://issuetracker.google.com/issues/228580728)) **Bug Fixes** - Clarified the documentation for `WindowInsets.ime` to state that `ime` insets are reported as far back as API 23, but only *animated* on 30+.

This bugfix ensures that text layout always triggers redraw (b/229727404). ([I1d49e](https://android-review.googlesource.com/#/q/I1d49e9b977c234c9bc0317def7918d7821b321eb), [b/229727404](https://issuetracker.google.com/issues/229727404)) ### Version 1.2.0-beta01 May 11, 2022 `androidx.compose.foundation:foundation:1.2.0-beta01` and `androidx.compose.foundation:foundation-layout:1.2.0-beta01` are released.

([Iba8a0](https://android-review.googlesource.com/#/q/Iba8a0196e68efce0afe0610a8b6e79fe3f02ee83)) - In the `LazyLayoutItemProvider` api instead of a factory returning the composable lambda by index we now have a simpler composable function Item accepting the index. ([Id2196](https://android-review.googlesource.com/#/q/Id21962ddb1fd14b8946d89c948d4f1779dc8fc8c)) - LazyLayoutItemsProvider is renamed to LazyLayoutItemProvider ([I0638c](https://android-review.googlesource.com/#/q/I0638c931ced98a63b63bf7e2122f1a14dbe37cf0)) - `LazyLayoutItemsProvider.itemsCount` is renamed to `itemCount` ([Id409c](https://android-review.googlesource.com/#/q/Id409c7afef79f35cc3e2ef019b9842c2ad507f58)) - Added Brush to `TextStyle` and `SpanStyle` to provide a way to draw text with gradient coloring. ([I53869](https://android-review.googlesource.com/#/q/I538698c22f5a03b57ed811ea733dd1194deaaa6a), [b/187839528](https://issuetracker.google.com/issues/187839528)) - `trimFirstLineTop`, `trimLastLineBottom` attributes of `LineHeightBehavior` changed into a single enum: `LineHeightTrim`. `LineHeightTrim` have values of 4 states defined by two booleans: `FirstLineTop`, `LastLineBottom`, Both and None ([Ifc6a5](https://android-review.googlesource.com/#/q/Ifc6a5912eab7a0e41ae6cd4045ea9cbdf3c0a146), [b/181155707](https://issuetracker.google.com/issues/181155707)) - Added `LineHeightBehavior` to the `TextStyle` and `ParagraphStyle. LineHeightBehavior` controls whether line height is applied to the top of the first line and to the bottom of the last line. It also defines the alignment of line in the space provided by `TextStyle`(`lineHeight`). For example it is possible to get a behavior similar to what CSS defines via `LineHeightBehavior(alignment = LineVerticalAlignment.Center, trimFirstLineTop=false, trimLastLineBottom = false)`. - `trimFirstLineTop`, `trimLastLineBottom` configurations works correctly only when `includeFontPadding` is false. ([I97332](https://android-review.googlesource.com/#/q/I973329a540ca9f5a6e225f1e5aaffeaa1ff9cc61), [b/181155707](https://issuetracker.google.com/issues/181155707)) - Added experimental `imeNestedScroll()` modifier so that developers can control the IME through scrolling. ([I60759](https://android-review.googlesource.com/#/q/I6075942f67d2fbbdde97e5ce58f6fc871e51b7bc)) **Bug Fixes** - Fixed regression where text fields would not hide the keyboard when removed from the composition while focused.

Overlapping requests will be queued. ([I43e7f](https://android-review.googlesource.com/#/q/I43e7f73af86615f08e2d2d05bfd05ac96d0c65e4), [b/216790855](https://issuetracker.google.com/issues/216790855)) - Concurrent `BringIntoViewRequester.bringIntoView` calls for rectangles that are completely overlapping will now only honor the larger rectangle's request. ([I34be7](https://android-review.googlesource.com/#/q/I34be70f23527e4fea694fd5266bbc127cc1d1b0b), [b/216790855](https://issuetracker.google.com/issues/216790855), [b/184760918](https://issuetracker.google.com/issues/184760918)) - Turned on default `includeFontPadding`. It is possible to turn off the `includeFontPadding` using `TextStyle.platformTextStyle` attribute. In the near future we will change the default behavior however until that time this allows us to better integrate line height improvements (aosp/2058653) and solve `TextField` clipping issues. ([I01423](https://android-review.googlesource.com/#/q/I01423d9a0042a1f3e462236e1fdadb60a20678fc), [b/171394808](https://issuetracker.google.com/issues/171394808)) - `Modifier.bringIntoViewRequester` no longer uses `onGloballyPositioned`. ([I630f5](https://android-review.googlesource.com/#/q/I630f552bc59f31e91852aeaf3345216bb1f8c403)) **External Contribution** - `MouseInjectionScope.scroll(delta = someDelta)` is now inverted on Android if we scroll vertically (if someDelta is positive, it will scroll downward) ([Ifb697](https://android-review.googlesource.com/#/q/Ifb697a9ae8bc05a2d54d0a6cb4018713e156baf8), [b/224992993](https://issuetracker.google.com/issues/224992993)) ### Version 1.2.0-alpha08 April 20, 2022 `androidx.compose.foundation:foundation:1.2.0-alpha08` and `androidx.compose.foundation:foundation-layout:1.2.0-alpha08` are released.

This will use fallback font names like sans-serif-medium internally on API 21-28. This is a behavior change as previously only weights 400 and 700 were supported on API 21-28. ([I380fe](https://android-review.googlesource.com/#/q/I380fecb5ba839eecbf0b08acbca6247082b605d7), [b/156048036](https://issuetracker.google.com/issues/156048036), [b/226441992](https://issuetracker.google.com/issues/226441992)) - Paragraph and MultiParagraph are now accepting Constraints parameter. Passing `Constraints.maxHeight` is a no-op at the moment but will allow to do some calculation in the future, like ellipsizing based on the height.

([Icd314](https://android-review.googlesource.com/#/q/Icd314177f35c2ba05d1042454ca47834cf196e10)) - Partial consumption (down OR position) has been deprecated in `PointerInputChange`. You can use `consume()` to consume the change completely. You can use `isConsumed` to determine whether or not someone else has previously consumed the change. - `PointerInputChange::copy()` now always makes a shallow copy. It means that copies of `PointerInputChange` will be consumed once one of the copies is consumed. If you want to create an unbound `PointerInputChange`, use constructor instead. ([Ie6be4](https://android-review.googlesource.com/#/q/Ie6be471e6ed2a843e38712922c2231fdfd26213a), [b/225669674](https://issuetracker.google.com/issues/225669674)) - New experimental `LazyLayout` API is introduced. This allows you to build your own components like `LazyColumn` of `LazyVerticalGrid`. Note that the API is in its early stages and can be changed in the future releases.

([I17b71](https://android-review.googlesource.com/#/q/I17b71a13ca810f3ead1b7b87245b31b8e5b28f91)) - `FocusOrder` has now been merged into `FocusProperties` and `focusProperties()` now has all the capabilities of `focusOrder()`. `FocusOrder` and `focusOrder()` have been deprecated. `focusOrder()` that accepts a `focusRequester` should be replaced with a `focusRequester()` modifier in combination with `focusProperties()`. This allows the modifiers to have a stronger separation of concerns. ([I601b7](https://android-review.googlesource.com/#/q/I601b751755bcfefd849c8a0c0d019e3eaf5d459c)) - `WindowInsets.asPaddingValues(Density)` was added to allow developers to do the conversion without needing to be in composition.

In most cases the annotations can be inferred by the compose compiler plugin so using these annotation directly should be rare . The cases that cannot be inferred include creating and using a custom applier, abstract composable functions (such as interface methods), fields or global variables that are composable lambdas (local variables and parameters are inferred), or when using `ComposeNode` or a related composable functions. For custom appliers the composable functions that calls `ComposeNode` or `ReusableComposeNode` need to add a `CompoableTarget` annotation for the function and any composable lambda parameter types. It is recommended, however, to create an annotation that is annotated with `ComposableTargetMarker` and then the marked annotation be used instead of `ComposableTarget` directly. A composable annotation marked with `ComposableTargetMarker` is equivalent to a `ComposbleTarget` with the fully qualified name of the attribute class as the applier parameter. For an example of using `ComposableTargetMarker` see `anroidx.compose.ui.UiComposable`.

For example, loading fonts from an app-specific backend, optionally locating pre-installed fonts on-device, or loading a font from a resource not provided by the current Font factories. - Expanded `Font.ResourceLoaded` API to support optional and async font loading. It is not recommended that application developers use this API directly. To add new types of fonts see AndroidFont. - `Font.AndroidResourceLoader` extension function allows construction of a `Font.ResourceLoader` when outside of composition. - Added `loadingStrategy` parameter to resource-based fonts, to allow async loading when resource font references downloadable fonts XML.

The file specifies a rule per line, where a rule in this case is a pattern for matching to methods or classes in the library. The syntax for these rules is a superset of the human-readable ART profile format that is used when using `adb shell profman --dump-classes-and-methods ...`. These rules take one of two forms to target either methods or classes. - A method rule will have the following pattern: -> - And a class rule will have the following pattern: - Here `` is one or more of the characters `H`, `S`, and `P` to indicate whether or not this method should be flagged as "Hot", "Startup", or "Post Startup". - The `` is the descriptor for the class that the targeted method belongs to. For example, the class `androidx.compose.runtime.SlotTable` would have a descriptor of `Landroidx/compose/runtime/SlotTable;`. - The `` is the signature of the method, and includes the name, parameter types, and return types of the method. For example, the method `fun isPlaced(): Boolean` on `LayoutNode` has the signature `isPlaced()Z`. - These patterns can have wildcards (`**`, `*`, and `?`) in order to have a single rule encompass multiple methods or classes. #### What do the rules do? - A method that has the flag `H` indicates that this method is a "hot" method, and should be compiled ahead of time. - A method that has the flag `S` indicates that it is a method which is called at startup, and should be compiled ahead of time to avoid the cost of compilation and interpreting the method at startup time. - A method that has the flag `P` indicates that it is a method which is called after startup. - A class that is present in this file indicates that it is used during startup and should be pre-allocated in the heap to avoid the cost of class loading. #### How does this work? - Libraries can define these rules which will be packaged in AAR artifacts. When an app is then built which includes these artifacts, these rules are merged together and the merged rules are used to build a compact binary ART profile that is specific to the app. ART can then leverage this profile when the app is installed on devices in order to ahead-of-time compile a specific subset of the application to improve the performance of the application, especially the first run. Note that this will have no effect on debuggable applications. ### Version 1.0.0-beta08 June 2, 2021 `androidx.compose.foundation:foundation:1.0.0-beta08` and `androidx.compose.foundation:foundation-layout:1.0.0-beta08` are released.

This changes removes a potential type error for non-nullable types where no default factory was provided. Previously this would provide a null reference for a non-nullable type. For nullable types consider supplying `{ null }` as the default factory. We do not recommend using locals with non-nullable types unless a sensible default can be provided. If no sensible default exists, the `defaultFactory` lambda should throw an exception. However throwing an exception means that consumers of the local will have an implicit dependency on it being provided that is not enforced by the type system.

Recomposition and withFrameNanos-based animation ticks are paused while the host Lifecycle is stopped. ([I38e11](https://android-review.googlesource.com/#/q/I38e11565b2fc776966b6b6984aceafd8a1e6fed1)) - Recomposer.runningRecomposers now offers a global StateFlow of read-only RecomposerInfo for observing ongoing composition state in the process. Prefer this API to Recomposer.current(), which is now deprecated. ([If8ebe](https://android-review.googlesource.com/#/q/If8ebe3959cfe71682ad372382d3b720035ef1605)) ### Version 1.0.0-alpha11 January 28, 2021 `androidx.compose.foundation:foundation:1.0.0-alpha11` and `androidx.compose.foundation:foundation-layout:1.0.0-alpha11` are released.

Using ScrollableColumn is less efficient comparing to LazyColumn when you have a large scrolling content because with LazyColumn we can only compose/measure/draw visible elements. To prevent users from going inefficient way we decided to deprecate ScrollableColumn and ScrollableRow and promote usages of LazyColumn and LazyRow instead. Users can still decide they don't need the lazy behaviour and use the modifiers directly like this: Column(Modifier.verticalScroll(rememberScrollState())) ([Ib976b](https://android-review.googlesource.com/#/q/Ib976b534e063a86a2c587762b786a23e32cc61b6), [b/170468083](https://issuetracker.google.com/issues/170468083)) - New `items(count: Int)` factory method for scope of LazyColumn/LazyRow/LazyVerticalGrid. `items(items: List)` and `itemsIndexed(items: List)` are now extension functions so you have to manually import them when used. New extension overloads for Arrays: items(items: Array) and itemsIndexed(Array) ([I803fc](https://android-review.googlesource.com/#/q/I803fc5f25fac55855c710ff5064f11525f7b6010), [b/175562574](https://issuetracker.google.com/issues/175562574)) - The deprecated AbsoluteArrangement was removed.

Added a factory method `createEmptyComposeRule()` that returns a `ComposeTestRule` and does not launch an Activity for you. Use this when you want to launch your Activity during your test, e.g. using `ActivityScenario.launch` ([I9d782](https://android-review.googlesource.com/#/q/I9d78283c27d87a3135071884e115bbd814492c47), [b/174472899](https://issuetracker.google.com/issues/174472899)) - animateAsState is now animateFooAsState, where Foo is the type of the variable being animated. e.g. Float, Dp, Offset, etc ([Ie7e25](https://android-review.googlesource.com/#/q/Ie7e25c8978996334b0dcc757b07df1434ff346aa)) - Density is now receiver scope for Arrangement interfaces.

However this is an API only change and multi-style text editing is not implemented yet. - Removed `initial` from EditingBuffer constructor parameters. ([I326d5](https://android-review.googlesource.com/#/q/I326d534a69911fdd39097cdb42e9341ee7987130)) - invalidate and compositionReference() are now deprecated in favor of currentRecomposeScope and rememberCompositionReference respectively. ([I583a8](https://android-review.googlesource.com/#/q/I583a8efa6e3d3bc303792b825b948b3722ada103)) - AnnotatedString is changed to extend from kotlin.CharSequence. Therefore length and subSequence are now instance functions, and extension functions are removed. ([Iaf429](https://android-review.googlesource.com/#/q/Iaf429c94da9f1867cc0815cb26933961a71cc629)) - Duration and Uptime will be replace with Long milliseconds, and this step removes the dependency of pointer input on those classes. ([Ia33b2](https://android-review.googlesource.com/#/q/Ia33b2d6835861501019481b388cb2c99441c346c), [b/175142755](https://issuetracker.google.com/issues/175142755), [b/177420019](https://issuetracker.google.com/issues/177420019)) - RememberObserver replaces CompositionLifecycleObserver and CompositionLifecycleObserver is now deprecated. `RememberObserver` is a replacement for `CompositionLifecycleObserver` with modified semantics and renamed methods. Changing to the new API can be done mechanically for objects that are only remembered once which is, and continues to be, the recommended practice. However, if a reference was remembered more than once in a composition `onRemembered` is called for each reference where `onEnter` is only called once. `onEnter` was called multiple time if the object was used in subcompositions, such as `WithConstraints` and `Scaffold` making the single `onEnter` call guarantee unreliable and it was removed for `RememberObserver`. `RememberObserver` adds `onAbandoned` which is called if the `RememberObserver` instance is returned from the callback passed to `remember` but was not remembered in the composition state and, therefore, will never have `onRemembered` called. This can occur if an exception terminates composition before completing or the composition is discarded because the state is was producing a composition for is no longer current or otherwise is no longer needed. If the instance of `RememberObserver` following the single reference recommendation above is tracking an external resource both `onForgotten` and `onAbandoned` each indicate that the resource is no longer needed. If the object is tracking work started or resources allocated in `onRemembered`, `onAbandoned` can be ignored as it will not be called if `onRemembered` is called.

The `insert()` method has been renamed to `insertTopDown()`. A new method, `insertBottomUp()`, was added. An applier either inserts nodes into the tree it is editing using `insertTopDown()` or `insertBottomUp()` depending on which performs better. Some trees, such as `LayoutNode` and `View`, are much more efficient to build bottom-up than top-down. Prior to this change, a stack of inserts was required to implement bottom-up which needed to be copied to every applier which needed bottom-up construction for performance. With this change an `Applier` overrides `insertBottomUp()` to build a tree bottom-up and `insertTopDown()` to build the tree top-down. ([Icbdc2](https://android-review.googlesource.com/#/q/Icbdc2929ab8fc8fce231d633b062fc80be5c10c9)) - Added painterResource API to handle opaquely loading Painter objects from either rasterized asset formats (like PNGs) or VectorDrawables.

As a result, the `PlacementScope.place()` method will not automatically mirror the position in right-to-left contexts anymore. If this is desired, use `PlacementScope.placeRelative()` instead. ([I873ac](https://android-review.googlesource.com/#/q/I873ac827e6c4d4bf6c85a80b7128174c61602945), [b/162916675](https://issuetracker.google.com/issues/162916675)) - Removed deprecated FilledTextField component.

It provides modifiers to fill the parent max size which solves the use case when the item should fill the viewport and the regular Modifier.fillMaxSize() doesn't work as the item is measured with infinity constraints. ([Ibd3b2](https://android-review.googlesource.com/#/q/Ibd3b21685641c22f7deaab1bb71785d8d6135058), [b/162248854](https://issuetracker.google.com/issues/162248854)) - Move dialog to ui ([I47fa6](https://android-review.googlesource.com/#/q/I47fa618a788e598182b782eab755defccaf45ebb)) - Added LazyColumnForIndexed/LazyRowForIndexed - versions of LazyColumnFor/LazyRowFor which provides both index and item in the itemCallback.

Remove unused OffsetBase interface 2. Align Offset and IntOffset classes to have a consistent API surface 3. Rename IntOffset.Origin to IntOffset.Zero to be consistent with Offset API 4. Moved nativeCanvas method off of Canvas interface to support consumers to create their own Canvas instances 5. Created stub EmptyCanvas class to refactor DrawScope to be a non-null parameter instead of lateinit and ensure non-nullability of the field 6. Renamed ClipOp enums to be Pascal Case 7. Renamed FilterQuality enums to be Pascal Case 8. Renamed StrokeJoin enums to be Pascal Case 9. Renamed PointMode enums to be Pascal Case 10. Renamed PaintingStyle enums to be Pascal Case 11. Renamed PathFillType enums to be Pascal Case 12. Renamed StrokeCap enums to be Pascal Case 13. Updated DrawCache implementation to no longer use lateinit params 14.

This was done in order to get behavior to scale up the underlying Painter if the layout size is larger than the intrinsic size of the painter while maintaining the aspect ratio. This behavior better matches expectations for providing fixed sizes to the Image while not affecting the default behavior if only the intrinsic size is used to compute the size of the composable.

([Icacdd](https://android-review.googlesource.com/#/q/Icacdd0909bc434cd5fd935c46e0a07b965c6a38d), [b/152735784](https://issuetracker.google.com/issues/152735784)) - ParentData composable is deprecated. You should either create a modifier which implements ParentDataModifier interface, or use LayoutTag modifier if you simply need to tag layout children to recognize them inside the measure block. ([I51368](https://android-review.googlesource.com/#/q/I51368a2cb132318f5466949297e5fa247c04d68a), [b/150953183](https://issuetracker.google.com/issues/150953183)) - Add OnPositionedModifier and OnChildPositionedModifier to replace OnPositioned and OnChildPositioned composable functions. ([I2ec8f](https://android-review.googlesource.com/#/q/I2ec8fb4687b0b85e18174178562149745c03c7fd)) - Disallow negative padding in LayoutPadding. LayoutOffset should be used instead for negative position offsets. ([Ifb5b1](https://android-review.googlesource.com/#/q/Ifb5b19b62ad11d5f2c0efd993acc19de39a65635)) - WithConstraints got LayoutDirection parameter ([I6d6f7](https://android-review.googlesource.com/#/q/I6d6f7d5fd9a4a0428e3ee188a9a3790e1cdaf083)) - Updated the `ComposeFlags.COMPOSER_PARAM` flag to be `true`, which will change the code generation strategy for the compose plugin. At a high level, this causes @Composable functions to be generated with an additional synthetic parameter, which is passed through to subsequent @Composable calls in order for the runtime to properly manage execution. This is a significant binary breaking change, however, should preserve source-level compatibility in all sanctioned usage of compose. ([I7971c](https://android-review.googlesource.com/#/q/I7971ca1b6525440c38643953645fa388131e31f0)) - Changed LayoutCoordinates to make providedAlignmentLines a Set instead of a Map and have LayoutCoordinates implement the get() operator instead for retrieving a value. This makes it easier for modifiers to modify one or more value of the set without creating a new collection for each modifier. ([I0245a](https://android-review.googlesource.com/#/q/I0245a750ed12e822d61fa7d87c52bd708996f55d)) - LayoutCoordinates no longer has a position property. The position property does not make sense when considering LayoutModifiers, rotation, or scaling. Instead, developers should use parentCoordinates and childToLocal() to calculate the transform from one LayoutCoordinate to another. LayoutCoordinates uses IntPxSize for the size property instead of PxSize. Layouts use integer pixel sizes for layouts, so all layout sizes should use integers and not floating point values. ([I9367b](https://android-review.googlesource.com/#/q/I9367be21c2c202c8b6ad889b50a29454773f41af)) - Improvements to the API surface of Constraints ([I0fd15](https://android-review.googlesource.com/#/q/I0fd1505ae9a68c067a82eff6ab02b43080fe153c)) - Added TextDirection.Content ([I48f36](https://android-review.googlesource.com/#/q/I48f3683066739b4d88b2e998f9b216a5cd874f8d)) - Ajdust the Toolbar Menu to show copy, cut, paste properly.
