Changelog

Sourced from cython's changelog.

0.29.24 (2021-07-14)

Bugs fixed

• Inline functions in pxd files that used memory views could lead to invalid C code if the module that imported from them does not use memory views. Patch by David Woods. (Github issue 1415)
• Several declarations in libcpp.string were added and corrected. Patch by Janek Bevendorff. (Github issue 4268)
• Pickling unbound Cython compiled methods failed. Patch by Pierre Glaser. (Github issue 2972)
• The tracing code was adapted to work with CPython 3.10.
• The optimised in operator failed on unicode strings in Py3.9 and later that were constructed from an external wchar_t source. Also, related C compiler warnings about deprecated C-API usage were resolved. (Github issue 3925)
• Some compiler crashes were resolved. Patch by David Woods. (Github issues 4214, 2811)
• An incorrect warning about 'unused' generator expressions was removed. (GIthub issue 1699)
• The attributes gen.gi_frame and coro.cr_frame of Cython compiled generators and coroutines now return an actual frame object for introspection, instead of None. (Github issue 2306)

0.29.23 (2021-04-14)

Bugs fixed

• Some problems with Python 3.10 were resolved. Patches by Victor Stinner and David Woods. (Github issues 4046, 4100)
• An incorrect "optimisation" was removed that allowed changes to a keyword dict to leak into keyword arguments passed into a function. Patch by Peng Weikang. (Github issue 3227)
• Multiplied str constants could end up as bytes constants with language_level=2. Patch by Alphadelta14 and David Woods. (Github issue 3951)
• PY_SSIZE_T_CLEAN does not get defined any more if it is already defined. Patch by Andrew Jones. (Github issue 4104)

0.29.22 (2021-02-20)

Features added

• Some declarations were added to the provided pxd includes. Patches by Zackery Spytz and John Kirkham. (Github issues 3811, 3882, 3899, 3901)

Bugs fixed

• A crash when calling certain functions in Py3.9 and later was resolved. (Github issue 3917)
• const memory views of structs failed to compile. (Github issue 2251)
• const template declarations could not be nested. Patch by Ashwin Srinath. (Github issue 1355)
• The declarations in the cpython.pycapsule module were missing their const modifiers and generated incorrect C code. Patch by Warren Weckesser. (Github issue 3964)
• Casts to memory views failed for fused dtypes. Patch by David Woods. (Github issue 3881)
• repr() was assumed to return str instead of unicode with language_level=3. (Github issue 3736)
• Calling cpdef functions from cimported modules crashed the compiler. Patch by David Woods. (Github issue 4000)
• Cython no longer validates the ABI size of the NumPy classes it compiled against. See the discussion in numpy/numpy#432
• A C compiler warning about enum value casting was resolved in GCC. (Github issue 2749)
• Coverage reporting in the annotated HTML file failed in Py3.9. Patch by Nick Pope. (Github issue 3865)
• The embedding code now reports Python errors as exit status.
• Long type declarations could lead to (harmless) random changes in the C file when used in auto-generated Python wrappers or pickled classes.
