Changelog

Sourced from cython's changelog.

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.

Other changes

• Variables defined as cpdef now generate a warning since this is currently useless and thus does not do what users would expect. Patch by David Woods. (Github issue #3959)

0.29.21 (2020-07-09)

Bugs fixed

• Fix a regression in 0.29.20 where __div__ failed to be found in extension types. (Github issue #3688)
• Fix a regression in 0.29.20 where a call inside of a finally clause could fail to compile. Patch by David Woods. (Github issue #3712)
• Zero-sized buffers could fail to validate as C/Fortran-contiguous. Patch by Clemens Hofreither. (Github issue #2093)
• exec() did not allow recent Python syntax features in Py3.8+ due to https://bugs.python.org/issue35975. (Github issue #3695)
• Binding staticmethods of Cython functions were not behaving like Python methods in Py3. Patch by Jeroen Demeyer and Michał Górny. (Github issue #3106)
• Pythran calls to NumPy methods no longer generate useless method lookup code.
• The PyUnicode_GET_LENGTH() macro was missing from the cpython.* declarations. Patch by Thomas Caswell. (Github issue #3692)
• The deprecated PyUnicode_*() C-API functions are no longer used, except for Unicode strings that contain lone surrogates. Unicode strings that contain non-BMP characters or surrogate pairs now generate different C code on 16-bit Python 2.x Unicode deployments (such as MS-Windows). Generating the C code on Python 3.x is recommended in this case. Original patches by Inada Naoki and Victor Stinner. (Github issues #3677, #3721, #3697)
• Some template parameters were missing from the C++ std::unordered_map declaration. Patch by will. (Github issue #3685)
• Several internal code generation issues regarding temporary variables were resolved. (Github issue #3708)
