 Huge thanks to the folks who volunteered their time to participate in the alpha and beta testing program. Your enthusiasm and invaluable feedback helped us shape these docs. A special shout out to our beta tester, [Debbie O'Brien](https://twitter.com/debs_obrien), who gave a talk about her experience using the React docs at React Conf 2021.
 
 Finally, thanks to the React community for being the inspiration behind this effort. You are the reason we do this, and we hope that the new docs will help you use React to build any user interface that you want.

 * **Development warnings.** Since these don't affect production behavior, we may add new warnings or modify existing warnings in between major versions. In fact, this is what allows us to reliably warn about upcoming breaking changes.
 * **APIs starting with `unstable_`.** These are provided as experimental features whose APIs we are not yet confident in. By releasing these with an `unstable_` prefix, we can iterate faster and get to a stable API sooner.
-* **Alpha and canary versions of React.** We provide alpha versions of React as a way to test new features early, but we need the flexibility to make changes based on what we learn in the alpha period. If you use these versions, note that APIs may change before the stable release.

 * **Undocumented APIs and internal data structures.** If you access internal property names like `__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED` or `__reactInternalInstance$uk43rzhitjg`, there is no warranty.  You are on your own.
 
 This policy is designed to be pragmatic: certainly, we don't want to cause headaches for you. If we bumped the major version for all of these changes, we would end up releasing more major versions and ultimately causing more versioning pain for the community. It would also mean that we can't make progress in improving React as fast as we'd like.
