Breaking Changes

●Issue #1

Deprecated type aliases have been removed. Users must now use the type directly instead of the alias.

●Issue #2

The Jest preset has been moved to the new `react-native/jest-preset` package. Update Jest configurations to use the new path.

●Issue #3

The deprecated `StyleSheet.absoluteFill` API has been removed.

●Issue #4

Support for End-Of-Life (EOL) Node.js versions and old minor versions has been dropped.

●Issue #5

Android: Deprecated `UIManagerHelper.getEventDispatcherForReactTag` and `UIManagerHelper.getEventDispatcher(ReactContext, UIManagerType Int)`. Use `getEventDispatcher` instead.

●Issue #6

Android: The `UIImplementation` class has been stubbed as it is unused in the new architecture.

●Issue #7

Android: `ReactTextUpdate` is now internal.

Migration Steps

  1. 1
    Update Jest configurations to use the new preset path: `react-native/jest-preset`.
  2. 2
    Replace usage of deprecated type aliases with the direct type.
  3. 3
    Replace usage of `StyleSheet.absoluteFill` with the appropriate direct style property.
  4. 4
    Ensure your Node.js version is not EOL or an old minor version.
