React Native: Locking Down the C++ API Surface
The dominant story today is a sweeping effort to classify React Native's internal C++ modules under a three-tier stable API model, alongside a handful of platform crash fixes on Android and rendering fixes on iOS. Developers using strict API mode or custom native modules should expect new build-time guardrails, not runtime changes.

Good morning. It's August 21st, and today's activity is dominated by one theme: React Native is methodically fencing off its internal C++ architecture.
Jakub Piasecki and Dawid Małecki pushed out well over a dozen pull requests classifying modules — feature flags, Hermes, resize observers, JS inspector tracing, consistency managers, native view config, and more — as public, private, or "for frameworks" under a new stable API model. The mechanism is consistent…
Second theme: Android crash fixes in the view manager property system. Two separate PRs from dennytosp — #58038 and #58039 — fix crashes when Fabric components declare nullable float or DimensionValue props and implement them with `@ReactProp`. Both were previously unrecognized types causing runtime exceptions at…
On iOS, commit 9f31d5a fixes dotted and dashed outline rendering on views without border radius — a rendering bug hiding since the outline API shipped, only caught because test coverage always paired non-solid styles with rounded corners. Separately, chrfalch's swift package manager work, PRs #58033 through #58035,…
What to remember: if you build custom native modules, expect stricter header boundaries soon. If you…
