Cython Changelog

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.

• 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.

3.1.5 (2025-10-20)

Bugs fixed

• Conversion from C++ strings longer than PY_SSIZE_T_MAX did not validate the length.

• Some non-Limited API code was incorrectly used in generated header files.

• Optimised unpacking of Python integers in expressions uses a slightly safer scheme.

• Empty return statements were not always reported when tracing.

• Value conversion errors when tracing C return statements no longer fail the trace but fall back to reporting None returns instead.
