v5.0.0

What's Changed

This release introduces a couple minor but technically breaking API changes, though it is not expected to break known applications.
See the CHANGELOG for details.

This release is also more thoroughly tested than previous ones:

• multithreading is now tested for thread safety against the free-threading build of Python 3.13
• roundtrips stability is now tested with property-based testing using hypothesis (instead of relying on a set of manually discovered examples). This allowed the discovery (and fixing) of a couple edge case bugs.

Python 3.10 and newer is supported.
