Update development status.

pyfuse3 (with Trio) is a critical dependency of S3QL, which I have
started maintaining again. This means pyfuse3 will receive enough
attention from me to keep it functional and tested.

 Development Status
 ------------------
 
-pyfuse3 is in beta. Bugs are likely.
+pyfuse3 is stable when used with Trio. The current maintainers ensure that bugs
+are addressed and pyfuse3 continues to work with new Python and libfuse
+versions. There is no plan to add new features or other non-bugfix work.
+However, pull requests for new features or other improvements may be accepted.
 
-pyfuse3 uses semantic versioning. This means backwards incompatible
-changes in the API will be reflected in an increase of the major
-version number.
+Using pyfuse3 with asyncio (rather than Trio) support is less well tested,
+there may be bugs, and some of them may not be easily fixable.
