 ## 0.6.1
 
 - First release on PyPI under the name `suou`.
+  - **BREAKING**: if you installed `sakuragasaki46-suou<=0.6.0` you need to uninstall and reinstall or things may break.
 - Fix `sqlalchemy.asyncio.SQLAlchemy()` to use context vars; `expire_on_commit=` is now configurable at instantiation. Fix some missing re-exports.
 
 ## 0.6.0
