1.3.0 - 2025-11-10

Removed

• Support for Python 3.9 (#1278)

Added

• Support for pytest 9 (#1279)

Notes for Downstream Packagers

• Tested Python versions include free threaded Python 3.14t (#1274)
• Tests are run in the same pytest process, instead of spawning a subprocess with pytest.Pytester.runpytest_subprocess. This prevents the test suite from accidentally using a system installation of pytest-asyncio, which could result in test errors. (#1275)
