3.1.6 (2025-10-23)

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

Bugs fixed
----------

* Unicode characters formatted from C integers with ``f"{value:c}"`` could result in
  invalid Python string objects since Cython 3.1.0.
  (Github issue :issue:`7240`)

* ``cythonize`` (program and function) now uses ``concurrent.futures.ProcessPoolExecutor``
  instead of ``multiprocessing.Pool`` to fix a hang on build failures in parallel builds.
  A possible work-around is to disable parallel builds.
  Patch by Sviatoslav Sydorenko.  (Github issue :issue:`7183`)
