Sourced from react-native's changelog.

v0.81.0

Breaking

• APIs: All react-native/Libraries/BugReporting APIs have been removed (9d4d8dcb02 by @​huntie)
• APIs: Add public JS API breaking change detection under yarn diff-api-snapshot script. (6b40f35032 by @​coado)
• APIs: Community CLI users: user-defined resolver.resolveRequest and serializer.getModulesRunBeforeMainModule Metro config now takes precedence over CLI defaults (fe2bcbf4ba by @​robhogan)
• Error Handling: Improve messaging and add error stack trace for uncaught throws. (5ba0e1f97a by @​vzaidman)
• Flow: The react-native package no longer ships with the flow directory (38acb4c074 by @​huntie)
• Node: Minimum Node version is now bumped to Node.js 22.14.0 (df39eadc03 by @​huntie)
• View: View no longer sets any default accessibility props, which should not result in visible changes in behaviour but may affect snapshot tests. (039a333df5 by @​javache)
• View: Upgrade View component to React 19. (eedd60b9e6 by @​EvanBacon)

Android specific

• APIs: Cleanup and internalize FpsDebugFrameCallback (cf6569bc18 by @​cortinico)

• FabricUIManager: Remove FabricUIManager.measure overload which accepts attachment positions (2ba86caf18 by @​NickGerleman)
• Kotlin: Migrate ViewManagerInterfaces to kotlin. Some types in code generated ViewManagerInterfaces might differ. e.g. this will start enforcing nullability in parameters of viewManagerInterface methods (e.g. String commands parameters are not nullable, view params are not nullable in any method, etc) (76ff1aa5c6 by @​mdvacca)
• Kotlin: Migrate com.facebook.react.ReactDelegate to Kotlin. Some users implementing this class in Kotlin could have breakages. (50ea5b4380 by @​mateoguzmana)
• Kotlin: Convert to Kotlin and internalize MountingManager (f33fdca876 by @​cortinico)
• textAlignVertical: Move textAlignVertical to paragraph attributes instead of text attributes (55fd8b26f8 by @​joevilches)

iOS specific

• RCTDisplayLink: Migrate RCTDisplayLink's API from RCTModuleData (70eeb9f541 by @​RSNara)
• SynchronouslyUpdateViewOnUIThread: SynchronouslyUpdateViewOnUIThread now accepts folly::dynamic instead of NSDictionary. Use https://github.com/facebook/react-native/blob/main/packages/react-native/ReactCommon/react/utils/platform/ios/react/utils/FollyConvert.h#L14 for conversion. (82279bd981 by @​sammy-SC)
