Thanks to +[@naveen521kk](https://github.com/naveen521kk) for updating the fork, and +everyone else who helped with rebuild issues. Also thanks to +[@jeremyd2019](https://github.com/jeremyd2019) for watching the external arm64 +runner while it rebuilt all those 940 packages and fixing arm64 related issues. + +There are some minor things to watch out for with this update: + +* We've enabled [PEP 668](https://peps.python.org/pep-0668/) by marking the + system site-packages directory as externally managed. To prevent this from + causing too many problems right away [we have patched our version of + pip](https://github.com/msys2/MINGW-packages/commit/4447a7ba7971d3480e7bd24951ec8e51328d23c9) + to only give a warning instead of an error if you install outside of a venv. + However, we may change this back to a real error in the future. If this is + causing any problems or if there are any concerns with re-enabling the error + in the future let us know. +* While not MSYS2 specific, 3.12 is the version that [dropped the included + distutils package](https://peps.python.org/pep-0632) and distutils is now only + available as part of setuptools. While the current setuptools should handle + our Python out of the box, there may be slight differences. This also means + that SETUPTOOLS_USE_DISTUTILS=stdlib no longer has any effect. +* As with every major Python update we had to drop a few packages that were + incompatible with the new version and for which no update or patch was + available. One notable package there is py2exe which does not support 3.12+ + right now and there is also no patch available, see [the upstream + issue](https://github.com/py2exe/py2exe/issues/191) for details. + ### 2024-11-03 - Disabling mingw-w64 wildcard support by default For historical reasons MSYS2 enabled wildcard support in mingw-w64 at build
