Good morning, it's June 3rd, 2026. React Native made significant breaking changes yesterday, primarily around removing legacy architecture support and tightening API boundaries.
The biggest architectural shift is the removal of the enable bridgeless architecture flag and global RN$Bridgeless checks in PR 57055. This eliminates the toggle between old and new architectures, forcing apps onto the bridgeless path. Combined with PR 57054's removal of new architecture flags from RCT React Native Factory on iOS, the framework is clearly pushing developers toward full adoption of the new architecture.
API cleanup dominated the remaining changes. The team removed several deprecated exports including Native Dialog Manager Android in PR 57047 and legacy Native Methods types. PR 57046 made DOM constructors throw illegal constructor errors, aligning React Native's web APIs closer to browser behavior. These aren't just housekeeping - they represent a significant tightening of the public API surface.
The Kotlin conversion continues with scroll view components moving from Java to Kotlin in PRs 57044 and 57045. While not breaking, this reflects ongoing modernization of the Android codebase that could affect native module developers extending these classes.
Several bug fixes addressed real user pain points. PR 57052 fixed sticky header press handling with shifted measurements, PR 57051 queued activity results before React context is ready, and PR 57050 respected JavaScript responder inside Fabric scroll views. These fixes target complex interaction scenarios that likely caused production issues.
Looking ahead, developers need to audit their bridgeless architecture readiness since the training wheels are off. The API removals suggest more aggressive deprecation cycles, so review your usage of internal React Native APIs. The team appears to be accelerating the transition to the modern architecture stack.
That's your React Native update for June 3rd.
