[dependabot]

Bumps react from 19.0.0 to 19.1.0.

Changelog

Sourced from react's changelog.

19.1.0 (March 28, 2025)

Owner Stack

• An Owner Stack is a development-only stack trace that helps identify which components are responsible for rendering a particular component. An Owner Stack is distinct from a Component Stack, which shows the hierarchy of components leading to an error.
• The captureOwnerStack API is only available in development mode and returns a Owner Stack, if available. The API can be used to enhance error overlays or log component relationships when debugging. #29923, #32353, #30306, #32538, #32529, #32538

React

• Enhanced support for Suspense boundaries to be used anywhere, including the client, server, and during hydration. #32069, #32163, #32224, #32252
• Reduced unnecessary client rendering through improved hydration scheduling #31751
• Increased priority of client rendered Suspense boundaries #31776
• Fixed frozen fallback states by rendering unfinished Suspense boundaries on the client. #31620

• Fixed a bug where dev-only methods were exported in production builds. React.act is no longer available in production builds. #32200
• Improved consistency across prod and dev to improve compatibility with Google Closure Complier and bindings #31808
• Improve passive effect scheduling for consistent task yielding. #31785
• Fixed asserts in React Native when passChildrenWhenCloningPersistedNodes is enabled for OffscreenComponent rendering. #32528
