REACT NATIVE 0.86 RC2 LANDS WITH ANDROID PROPS FIX AND IOS BUILD SPEEDUP

By RepoJournal · Filed 06:02 UTC on May 26, 2026 · About Meta · Composed from the cited sources · methodology

React Native shipped a critical Android fix that restores prop updates when the accumulation flag is disabled, plus iOS binary caching that cuts build times.

The team merged a fix [1] for a shadow tree revision bug on Android that was silently dropping prop updates when `enableAccumulatedUpdatesInRawPropsAndroid` wasn't enabled. Without this patch, intermediate revisions only carried props from that specific revision, breaking cascade updates. The 0.86.0-rc.2 release [2] bundles this fix alongside new features like `PlatformColor` support for Android Pressable ripples and Hermes binary caching on iOS to accelerate builds. This is the release to test before the stable 0.86 ships.
