Open dependabot[bot] opened this issue 3 weeks ago • 0 comments

Bumps cython from 3.0.12 to 3.2.3.

Release notes

Sourced from cython's releases.

3.2.2

No release notes provided.

3.2.1

No release notes provided.

3.2.0 (2025-11-05)

(Complete changelog for the 3.2.0 release, including pre-releases.)

Features added

  • Builtin exception types are now inferred. (Github issue :issue:6908)

  • The list of known, inferred and optimised Python builtins was updated. range is now considered a type. ascii, bin, format, hex, oct were added as functions. (Github issue :issue:6931)

  • The f-string syntax was extended according to PEP-701. (Github issue :issue:5452)

  • t-strings are implemented according to PEP-750. The implementation backports the template classes but prefers existing backports if installed separately. (Github issue :issue:6811)

  • Unknown return type annotations with -> are no longer rejected but produce warnings. This allows better integration with Python type hints that are not always usable for Cython. -> None is also allowed now. Patch by jpe. (Github issue :issue:6946)

  • The runtime Python dispatch for fused functions is substantially faster. (Github issues :issue:1385, :issue:6996)

  • Freelists (via cdef class decorator and for internally used types such as async) are now also used in the Limited API and with extension type specs enabled. (Github issue :issue:7151)

  • Module imports now quickly check for an already imported module to speed up reimports. Patch by Lysandros Nikolaou. (Github issue :issue:7035)

  • Type checks on PEP-604 union types (int | None) are optimised into separate checks. (Github issue :issue:6935)

  • Assignments to the PEP-604 union type float | None allow any suitable Python number as input and convert it to a Python float automatically. (Github issue :issue:5750)

Changelog

Sourced from cython's changelog.

3.2.3 (2025-12-14)

Features added

  • The C-API declarations were updated to include the new PyList_*() functions. (Github issue :issue:7291)

  • The Py_mod_gil module setting can now be changed with a C macro, overriding the freethreading_compatible directive setting. (Github issue :issue:7404)

Bugs fixed

  • t-strings lost the last element when compiled for the Limited API. (Github issue :issue:7381)

  • The array.data property of the cpython.array declarations generated a useless exception check that degraded its use in nogil code. (Github issue :issue:7408)

  • Parallel builds with the cythonize command could request more processes than allowed by the platform, thus failing the build. (Github issue :issue:7384)

  • A minor thread sanitizer issue was resolved. (Github issue :issue:7383)

3.2.2 (2025-11-30)

Features added

  • The C-API declarations were updated to include the new PyDict_*Ref() functions. (Github issue :issue:7291)

Bugs fixed

  • Iteration over literal sequences and strings in generators generated invalid C code since 3.2.0. This was a regression due to the C array iteration optimisation in :issue:6926, which is now disabled inside of generators. (Github issue :issue:7342)

  • Calling special methods of known exception types failed with an AttributeError. (Github issue :issue:7342)
