Important: Python 3.7 is the minimum supported version, due to difficulty of testing old releases, and the fact that everything older has been deprecated a long time ago (e.g. 3.6 at the end of 2021).
Otherwise, a minor release:
- Improve error handling in some corner cases (not expected to have any real-life impact, but who knows).
- Improved testing coverage and test infrastructure.
- Modernise parts of the C code based on recent Python version guidelines.
- Add a simple security policy and contribution guidelines.
