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
