I'm happy to announce the 11.0 release of PyObjC, slightly delayed from the
normal major release in October.
This release has two major features:
Support for the macOS 15.2 SDK, including new bindings for the frameworks
MediaExtension and DeviceDiscoveryExtension
Experimental support for GIL-less operation in the free-threaded build of
Python 3.13
The latter feature is an important reason for the delay: Supporting GIL-less
operation required reworking parts of the internals of PyObjC, both to rely on
other locks than the GIL and to avoid CPython APIs that are known to be
problematic when the GIL isn't present ("borrowed references" for anyone
familiar with the CPython API).
Free-threaded support is experimental at this point in time and has seen only
limited testing for multi-threading. I've also focussed on getting the basics
right, and have not worked at optimizing free-threading support. Expect
improvements in future releases.
With PyObjC 11 I'm dropping support for Python 3.8, given that that's gone out
of support by the CPython team.
Finally, there's a number of bug fixes and smaller features mentioned in the
changelog at https://pyobjc.readthedocs.io/en/latest/changelog.html
