4.1.0

• Add support for autoExhaustiveTypes config and a @nonExhaustive directive to control automatic exhaustive checks for unions/interfaces.

• Add React-free mode support and split React APIs into RescriptRelayReact.

  • New compiler config: rescriptRelayMode: "Default" | "NonReact" (defaults to "Default").
  • PPX -non-react
  • Mark @rescript/react and react-relay as optional peer deps so non‑React usage does not require them.

• BREAKING: Move all React-specific APIs out of RescriptRelay into RescriptRelayReact.

  • RescriptRelay.Context.Provider -> RescriptRelayReact.Context.Provider
  • RescriptRelay.useEnvironmentFromContext -> RescriptRelayReact.useEnvironmentFromContext
  • RescriptRelay.useSubscribeToInvalidationState -> RescriptRelayReact.useSubscribeToInvalidationState

  Migration:

  • Update imports/usages in app code to reference RescriptRelayReact for the APIs listed above.
  • For non‑React usage, set rescriptRelayMode: "NonReact" in relay.config.js and pass -non-react to the PPX.
