 ## Changelog
 
+### 0.6
+
+- Drop support for Python 3.6 and 3.7, which have reached end of life.
+- Add `EventLoopPolicy` to simplify integration with pytest-asyncio 0.23+,
+  and use it for the internal tests.
+- Make `Socket.write` and `Socket.recv_into` accept arbitrary buffer-protocol
+  objects.
+- Various packaging and developer experience improvements:
+  - Put the packaging metadata in pyproject.toml, removing setup.cfg.
+  - Pin versions for CI in requirements.txt using pip-compile.
+  - Use pre-commit to enforce flake8 and pip-compile.
+  - Remove wheel from `build-system.requires` (on setuptools advice).
+  - Test against Python 3.11 and 3.12.
+  - Run CI workflow against pull requests.
+
 ### 0.5
 
 - Map port 0 to an unused port.
