3.1.0 alpha 1 (2024-11-08)

Features added

• Support for freethreading builds of CPython 3.13 was added. It comes with a new directive freethreading_compatible=True to mark modules as free-threading compatible (Py_mod_gil). https://github.com/cython/cython/issues?q=label%3A"nogil+CPython" Patches by Lysandros Nikolaou and Nathan Goldbaum. (Github issue :issue:6162)

• Support for monitoring Cython modules via sys.monitoring in CPython 3.13+ was added. For coverage reporting, this needs to be disabled with -DCYTHON_USE_SYS_MONITORING=0 as long as coverage.py does not support sys.monitoring for coverage plugins. (Github issue :issue:6144)

• Many issues with the Limited C-API were resolved. It is now sufficient to define the macro Py_LIMITED_API to activate the support. https://github.com/cython/cython/issues?q=label%3A%22limited+api%22

• Support for GraalPython was improved (but is still incomplete).

• Several issues with the gdb support were resolved. Patches by Kent Slaney. (Github issues :issue:5955, :issue:5948)

• typing.Union[SomeType, None] and SomeType | None are now understood and mean the same as typing.Optional[SomeType], allowing None in type checks.

Bugs fixed

• Attribute lookups failed on the bool builtin type. (Github issue :issue:6905)

• Type checks on or-ed union types could incorrectly return false. (Github issue :issue:6420)

• Negative list indexing could accidentally wrap around twice in PyPy and the Limited API.

• Iterating over literal sequences with starred (unpacked) items could infer a wrong type for the loop variable and fail to assign the values. (Github issue :issue:6924)

• Calls to C functions taking exception types failed to check for a None argument. (Github issue :issue:6420)

• Fused functions had an incorrect __module__ attribute. (Github issue :issue:6897)

• The type of Cython implemented functions had an incorrect __module__ attribute. (Github issue :issue:6841)

• Errors while indexing into bytearray or str in nogil sections could crash. (Github issue :issue:6947)

• bytearray.append() could silently accept some invalid character numbers.

• The C++11 <type_traits> header was included regardless of the C++ version. (Github issue :issue:6896)

• PyDict_GetItemStringRef() was accidentally used in older Limited API versions. (Github issue :issue:6914)

• abort() was used but not always available in the Limited API. (Github issue :issue:6918)

• Some dependencies were missing from the depfile. (Github issue :issue:6938)

• Embedded function signatures were not always separated from the existing docstring. (Github issue :issue:6904)

• numpy.math was missing from Cython/Includes/ and could not be cimported. (Github issue :issue:6859)

Looks like cython is up-to-date now, so this is no longer needed.
