gevent v21.12.0 Release Notes

Release Date: 2021-12-11 // 7 months ago
  • ๐Ÿ”‹ Features

    • โšก๏ธ Update autoconf files for Apple Silicon Macs. Note that while there are reports of compiling gevent on Apple Silicon Macs now, this is not a tested configuration. There may be some remaining issues with CFFI on some systems as well. See :issue:1721.
    • ๐Ÿง Build and upload CPython 3.10 binary manylinux wheels.

    Unfortunately, this required us to stop building and uploading CPython 2.7 binary manylinux wheels. Binary wheels for 2.7 continue to be available for Windows and macOS. See :issue:1822.

    • Test and distribute musllinux_1_1 wheels. See :issue:1837.
    • โšก๏ธ Update the tested versions of PyPy2 and PyPy3. For PyPy2, there should be no user visible changes, but for PyPy3, support has moved from Python 3.6 to Python 3.7. See :issue:1843.

    ๐Ÿ›  Bugfixes

    • ๐Ÿ Try to avoid linking to two different Python runtime DLLs on Windows. See :issue:1814.
    • ๐Ÿง Stop compiling manylinux wheels with -ffast-math. This was implicit in -Ofast, but could alter the global state of the process. Analysis and fix thanks to Ilya Konstantinov. See :issue:1820.
    • ๐Ÿ›  Fix hanging the interpreter on shutdown if gevent monkey patching occurred on a non-main thread in Python 3.9.8 and above. (Note that this is not a recommended practice.) See :issue:1839.
