### Changes for libraries depending on internals {/*changes-for-libraries-depending-on-internals*/}
### Libraries depending on React internals may block upgrades {/*libraries-depending-on-react-internals-may-block-upgrades*/}
This release includes changes to React internals that may impact libraries that ignore our pleas to not use internals like `SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED`. These changes are necessary to land improvements in React 19, and will not break libraries that follow our guidelines.

In the future we will more aggressively block accessing internals from React to discourage usage and ensure users are not blocked from upgrading.
