Flow 0.286 introduced stricter constant-condition detection that flags build-time feature flags (supportsMutation, supportsHydration, isPrimaryRenderer, enableProfiling, etc.) and narrowed null checks. Added inline $FlowFixMe suppressions to preserve existing runtime behavior.
react-client
This is an experimental package for consuming custom React streaming models.
Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.
Use it at your own risk.
