Release Notes

python-greenlet/greenlet (greenlet)

v3.3.1

Compare Source

==================

• 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/>_.

v3.3.0

Compare Source

==================

• 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.

v3.2.4

Compare Source

==================

.. 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
  are not tested by this project's CI.
• Fix an assertion error on debug builds of Python 3.14 when using the
  experimental JIT. See issue 460 <https://github.com/python-greenlet/greenlet/issues/460>_.
