React Native 0.83 is the first release with no user-facing breaking changes. 0.82 users can upgrade without any code changes.
The release includes React 19.2, bringing <Activity> and useEffectEvent APIs to React Native.
What’s New
DevTools gets major upgrades:
- Network Inspection: View all network requests with timings, headers, and response previews. See where each request originated via the Initiator tab.
- Performance Tracing: Record JavaScript execution, React Performance tracks, and Network events in one timeline.
- Desktop App: DevTools now ships as a standalone app.
Web Performance APIs are now stable and work in production builds, enabling real-world performance monitoring.
IntersectionObserver (Canary): Async layout intersection tracking for lazy loading and visibility detection.
Hermes V1 (Experimental): Continued performance improvements in the compiler and VM.
iOS optimization: Compile out the Legacy Architecture with RCT_REMOVE_LEGACY_ARCH=1. In Meta’s tests, build time dropped from 73s to 58s, and app size from 51.2MB to 48.2MB.
Security Note
React Native 0.83.0 ships with React 19.2.0. While not directly affected by CVE-2025-55182, if you’re in a monorepo with React Server Components packages, upgrade them immediately.
