React Native: Locking Down the C++ API Surface
The bulk of today's activity is a sustained rollout of C++ stable API visibility guards across renderer modules, alongside a fixed Animated regression that broke listeners on derived native values since version 0.78.

Good day. It's September 3rd, 2026, and this is your React Native briefing.
The dominant story today isn't a single feature, it's an architectural cleanup effort: engineer Jakub Piasecki and colleagues are methodically applying the new three-tier C++ stable API visibility model across the codebase. We saw this hit image components, mounting, image manager, component registry, text layout…
Second theme: Animated had a real regression, now fixed. Commit ce621bb resolves an issue where `addListener` silently stopped firing on any animated value derived through add, subtract, multiply, divide, modulo, diff-clamp, or interpolate — but only for natively driven animations, and only since version 0.78. The…
Smaller but notable: PR 58311 shrinks a memory regression from Grid layout styles by lazily allocating grid-specific fields instead of paying the cost on every node. And two Babel preset fixes — one around private class field transforms on legacy Hermes profiles, another correcting how duplicate keys in…
What's next: expect the stable API guard rollout to keep expanding module by module. If you maintain a framework built on React Native internals, start watching for strict API warnings.
