[dependabot]

Updates the requirements on cython to permit the latest version.

Changelog

Sourced from cython's changelog.

0.29.33 (2023-01-06)

Features added

• The cythonize and cython commands have a new option -M / --depfile to generate .dep dependency files for the compilation unit. This can be used by external build tools to track these dependencies. The cythonize option was already available in Cython :ref:0.29.27. Patches by Evgeni Burovski and Eli Schwartz. (Github issue :issue:1214)

Bugs fixed

• const fused types could not be used with memory views. Patch by Thomas Vincent. (Github issue :issue:1772)

• wstr usage was removed in Python 3.12 and later (PEP-623). (Github issue :issue:5145)

• A type check assertion for Cython functions failed in debug Python builds. (Github issue :issue:5031)

• Fixed various compiler warnings. Patches by Lisandro Dalcin et al. (Github issues :issue:4948, :issue:5086)

• Fixed error when calculating complex powers of negative numbers. (Github issue :issue:5014)

• Corrected a small mis-formatting of exception messages on Python 2. (Github issue :issue:5018)

• The PyUnicode_AsUTF8AndSize() C-API function was missing from the CPython declarations. (Github issue :issue:5163)

• A performance problem in the compiler was resolved when nesting conditional expressions. (Github issue :issue:5197)

• Test suite problems with recent NumPy and CPython versions were resolved. (Github issues :issue:5183, :issue:5190)

Other changes

• The undocumented, untested and apparently useless syntax from somemodule cimport class/struct/union somename was deprecated in anticipation of its removal in Cython 3. The type modifier is not needed here and a plain cimport of the name will do. (Github issue :issue:4905)
