# 1.13.0-alpha01 (September 2026)

_Changes since 1.12.0_

## Known issues

### Web

- RuntimeError: memory access out of bounds error ([YouTrack issue](https://youtrack.jetbrains.com/issue/CMP-10732)). Workaround is to disable the snapshot cache: `ComposeUiFlags.useSnapshotCache = false`

## Highlights

### Desktop

- Implemented support for [AppCDS](https://dev.java/learn/jvm/cds-appcds/) and [AOT](https://openjdk.org/jeps/514), which can significantly speed up application startup [#5644](https://github.com/JetBrains/compose-multiplatform/pull/5644)

### Web

- `ComposeViewportConfiguration` is no longer experimental [#3297](https://github.com/JetBrains/compose-multiplatform-core/pull/3297), [#3300](https://github.com/JetBrains/compose-multiplatform-core/pull/3300)

## Breaking Changes

### Gradle Plugin

- Deleted deprecated Compose Gradle Plugin API: `compose.web.targets(...)` [#5685](https://github.com/JetBrains/compose-multiplatform/pull/5685)

Shouldn't it be in "Migration Notes"?

The API is deprecated quite time and there is no a migration. The usage should be just deleted on project side


## Migration Notes

### Multiple Platforms

- Skottie is no longer included in the Skiko core binary and is no longer bundled with Compose Multiplatform. To continue using Skottie, add `org.jetbrains.skiko:skiko-skottie` to `commonMain`. If your project targets desktop, also add `org.jetbrains.skiko:skiko-skottie-awt-runtime-all` to `desktopMain` [#3234](https://github.com/JetBrains/compose-multiplatform-core/pull/3234)
- Removed `ComposeUiFlags.useLegacyRenderNodeLayers` flag used to revert legacy (pre 1.8) render node layers for cases without `androidx.compose.ui.graphics.layer.GraphicsLayer` [#3213](https://github.com/JetBrains/compose-multiplatform-core/pull/3213)

### Desktop

- Renamed `AlignedToScreen` to `AlignedToScreenAvailableBounds` and `CenteredOnScreen` to `CenteredInScreenBounds` to clarify their behavior. `CenteredInScreenBounds` now actually centers on the screen (ignoring insets) [#3291](https://github.com/JetBrains/compose-multiplatform-core/pull/3291)

### Android

- The minimum supported SDK is raised to 24 [#3351](https://github.com/JetBrains/compose-multiplatform-core/pull/3351)

## Features

### HTML library

- Add `StyleScope.inset` extension functions [#5194](https://github.com/JetBrains/compose-multiplatform/pull/5194)

### Multiple Platforms

- Add support for `mediaQuery` calls which allows to modify Composables depending on device characteristics [#3339](https://github.com/JetBrains/compose-multiplatform-core/pull/3339)
Comment thread
janinadavydova marked this conversation as resolved.

### iOS

- Use `UIView` layout and draw phases to run corresponding operation for Compose containers [#3212](https://github.com/JetBrains/compose-multiplatform-core/pull/3212)
- Added possibility to configure `spellCheckingType` for textfields with `usingNativeTextInput = true` via `PlatformImeOptions` [#3305](https://github.com/JetBrains/compose-multiplatform-core/pull/3305)
- Support iOS Dynamic Type font scaling based on accessibility settings [#3306](https://github.com/JetBrains/compose-multiplatform-core/pull/3306)
- Support preferred-size reporting for Compose hosting views (`ComposeHostingView` / `ComposeHostingViewController`) embedded in UIKit or SwiftUI through `sizeThatFits` proposals. Keep the default `ComposeContainerConfiguration.preferredSizeReportingStrategy = PreferredSizeReportingStrategy.SizeThatFits`, for UIKit and SwiftUI on iOS 16 and later. For SwiftUI on iOS < 16, use `PreferredSizeReportingStrategy.IntrinsicContentSize` [#2984](https://github.com/JetBrains/compose-multiplatform-core/pull/2984)

### Desktop

- Added a new `WindowPositionProvider.CenteredInScreenBounds(DpOffset)` function that centers on the screen [#3291](https://github.com/JetBrains/compose-multiplatform-core/pull/3291)
- Disabled Swing double buffering to reduce memory footprint [#3336](https://github.com/JetBrains/compose-multiplatform-core/pull/3336)
- _(prerelease fix)_ Bump Compose Hot Reload to [1.3.0-alpha01](https://github.com/JetBrains/compose-hot-reload/releases/tag/v1.3.0-alpha01) [#5683](https://github.com/JetBrains/compose-multiplatform/pull/5683)

## Fixes

### Multiple Platforms

- Fixes that `GraphicsLayer` with `CompositingStrategy.ModulateAlpha` does not apply `alpha` value without extra invalidation [#3204](https://github.com/JetBrains/compose-multiplatform-core/pull/3204)

- Fix `BasicTextField` focus handoff between nested Compose iOS scenes [#3203](https://github.com/JetBrains/compose-multiplatform-core/pull/3203)

### Desktop
