3.3.1 (2026-01-23)

• Publish Windows ARM binary wheels, where available.
• Fix compilation for 3.14t on Windows.
• Publish Windows 3.14t binary wheels for Intel.
• Switch from Appveyor for Windows to Github Actions.
• Fix compilation on MIPS with GCC 15 and binutils 2.45. See PR 487 by Rosen Penev <https://github.com/python-greenlet/greenlet/pull/487>_. Note that this is not a platform tested by this project's CI.
• Move most project metadata into the static pyproject.toml file. This updates licensing information to use the modern License-Expression field. See PR 480 by mrbean-bremen <https://github.com/python-greenlet/greenlet/pull/480/>_.

3.3.0 (2025-12-04)

• Drop support for Python 3.9.

• Switch to distributing manylinux_2_28 wheels instead of manylinux2014 wheels. Likewise, switch from musllinux_1_1 to 1_2.

• Add initial support for free-threaded builds of CPython 3.14. Due to limitations, we do not distribute binary wheels for free-threaded CPython on Windows. (Free-threaded CPython 3.13 may work, but is untested and unsupported.)

  .. caution::

  Under some rare scenarios with free-threaded 3.14, the interpreter may crash on accessing a variable or attribute or when shutting down. If this happens, try disabling the thread-local bytecode cache. See the greenlet documentation for more details. See PR 472 by T. Wouters <https://github.com/python-greenlet/greenlet/pull/472>_ for the initial free-threaded support and a discussion of the current known issues.

3.2.4 (2025-08-07)

.. note::

The 3.2.x series will be the last to support Python 3.9.

• Various small build/test changes for less common configurations (e.g., building CPython with assertions enabled but NOT debugging), contributed by Michał Górny. Note that while greenlet will BUILD in a free-threaded Python, it will cause the GIL to be allocated and used, and memory may leak. Also note that these configurations
