Release Notes

cython/cython (Cython)

v0.29.37

Compare Source

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

Bugs fixed

• Fix a potential crash while cleaning up subtypes of externally imported extension
  types when terminating Python. This was introduced in Cython 0.29.35.

• Fix a complex related compile error on Windows.
  (Github issue :issue:5512)

• Compiling fused types used in pxd files could crash Cython in Python 3.11+.
  (Github issues :issue:5894, :issue:5588)

• cythonize failed to consider the CYTHON_FORCE_REGEN env variable.
  Patch by Harmen Stoppels. (Github issue :issue:5712)

.. _0.29.36:

v0.29.36

Compare Source

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

Bugs fixed

• Async generators lost their return value in PyPy.
  (Github issue :issue:5465)

• The outdated C macro _PyGC_FINALIZED() is no longer used in Py3.9+.

• The deprecated Py_OptimizeFlag is no longer used in Python 3.9+.
  (Github issue :issue:5343)

• Using the global __debug__ variable but not assertions could lead to compile errors.

.. _0.29.35:

v0.29.35

Compare Source

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

Bugs fixed

• A garbage collection enabled subtype of a non-GC extension type could call into the
  deallocation function of the super type with GC tracking enabled. This could lead
  to crashes during deallocation if GC was triggered on the type at the same time.
  (Github issue :issue:5432)

• Some C compile failures and crashes in CPython 3.12 were resolved.

• except + nogil was syntactically not allowed.
  except +nogil (i.e. defining a C++ exception handling function called nogil)
  is now disallowed to prevent typos.
  (Github issue :issue:5430)

• A C compile failure in PyPy 3.10 was resolved.
  Patch by Matti Picus. (Github issue :issue:5408)

• Cython modules now use PEP-489 multi-phase init by default in PyPy 3.9 and later.
  Original patch by Matti Picus. (Github issue :issue:5413)

• API header files generated by different Cython versions can now be included in the
  same C file.
  (Github issue :issue:5383)

• Function signatures containing a type like tuple[()] could not be printed.
  Patch by Lisandro Dalcin. (Github issue :issue:5355)

.. _0.29.34:

v0.29.34

Compare Source

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

Bugs fixed

• A reference leak of the for-loop list/tuple iterable was resolved if the for-loop's
  else: branch executes a break for an outer loop.
  (Github issue :issue:5347)

• Some C compile failures in CPython 3.12 were resolved.

• Some old usages of the deprecated Python imp module were replaced with importlib.
  Patch by Matúš Valo. (Github issue :issue:5300)

  Patches by Eli Schwartz. (Github issues :issue:5279, :issue:5291)

.. _0.29.33:

v0.29.33

Compare Source

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

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)

• Properly disable generation of descriptor docstrings on PyPy since they cause crashes.
  It was previously disabled, but only accidentally via a typo.
  Patch by Matti Picus. (Github issue :issue:5083)

• The cpow directive of Cython 3.0 is available as a no-op.
  (Github issue :issue:5016)
