Release Notes

python-greenlet/greenlet (greenlet)

v3.5.5

Compare Source

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

• Link the C++ runtime statically into the Windows wheels again, as the
  Appveyor builds did through 3.3.0. Since 3.3.1 _greenlet.pyd
  imported MSVCP140.dll, which no Windows CPython distribution ships,
  so importing greenlet failed on machines without the Visual C++
  redistributable. See issue 525 <https://github.com/python-greenlet/greenlet/issues/525>_. Issue
  and pull request by Daniel Sticker.

.. note::
Binary 3.15 wheels are now built with 3.15.0rc1. This should be
compatible with future 3.15 releases and is believed compatible
with 3.15b4 as well (but not earlier versions).

v3.5.4

Compare Source

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

• Fix a crash (segfault) on free-threaded builds of Python 3.14 and
  later when the garbage collector runs while a greenlet that was
  started from a non-empty C-stack-reference state is active.
  See issue 515 <https://github.com/python-greenlet/greenlet/issues/515>_.
  Thanks to ddorian and Kumar Aditya.

• Fix a potential use-after-free on free-threaded builds of Python 3.14
  and later when the garbage collector runs while a greenlet is
  suspended holding a _PyCStackRef (for example, mid attribute
  resolution). See
  issue 515 <https://github.com/python-greenlet/greenlet/issues/515>_.
  Thanks to ddorian and Kumar Aditya.

• Fix a deadlock on free-threaded builds when a greenlet switch happened
  while a PyCriticalSection was held -- for example inside asyncio's
  Task.__step, which holds one on the running task for the duration of
  the step. See PR 519 <https://github.com/python-greenlet/greenlet/pull/519/>.
  Thanks to ddorian and Kumar Aditya.

.. note::
Binary 3.15 wheels are now built with Python 3.15b4. These may not
be compatible with earlier or later versions of 3.15. Binary
3.15 wheels of greenlet from previous releases (e.g., 3.5.3)
may not be compatible with Python 3.15b4.

v3.5.3

Compare Source

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

• Fix a crash on free-threaded builds when multiple greenlets were
  holding a critical section on an object and the GIL for the thread
  was dropped. See issue 513 <https://github.com/python-greenlet/greenlet/issues/513>_. Thanks
  to ddorian.

v3.5.2

Compare Source

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

• The minimum supported version of Python 3.15 is now 3.15b2.
• Fix some garbage-collection related crashes on free-threaded Python
  3.15. Thanks to Kumar Aditya in PR #&#8203;511 <https://github.com/python-greenlet/greenlet/pull/511>_.
• Improve garbage collection of greenlets. This mostly applies to
  Python 3.15. Thanks to Kumar Aditya in PR #&#8203;512 <https://github.com/python-greenlet/greenlet/pull/512>_.
