After a bit of research and development, R3F is now compatible with React 19.2, including the Activity feature!
Why did this take some effort, you might wonder? When React bumped to version 19.2.x, they also bumped the internal reconciler up a version which was not backwards compatible with 19.1.x. This put us in an awkward position of either making a breaking change in the middle of R3F v9, bump to another major just because of an internal detail from React or get creative. We chose to get creative and R3F is compatible with all versions of React between 19.0 and 19.2. The downside is we had to bundle the reconciler with R3F, but react-dom already does this so for now it is the best solution available.
Forcing breaking changes on libraries is likely not what the React teams intended so we will be working with them to try to avoid this in the future.
Happy coding.
