Release Notes

cython/cython (cython)

v3.0.9

Compare Source

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

Features added

• Assigning const values to non-const variables now issues a warning.
  (Github issue :issue:5639)

• Using noexcept on a function returning Python objects now issues a warning.
  (Github issue :issue:5661)

• Some C-API usage was updated for the upcoming CPython 3.13.
  Patches by Victor Stinner et al. (Github issues :issue:6003, :issue:6020)

• The deprecated Py_UNICODE type is no longer used, unless required by user code.
  (Github issue :issue:5982)

• std::string.replace() declarations were added to libcpp.string.
  Patch by Kieran Geary. (Github issue :issue:6037)

Bugs fixed

• Cython generates incorrect (but harmless) self-casts when directly calling
  final methods of subtypes. Lacking a better solution, the errors that recent
  gcc versions produce have been silenced for the time being.
  Original patch by Michał Górny. (Github issue :issue:2747)

• Unused variable warnings about clineno were fixed when C lines in tracebacks are disabled.
  (Github issue :issue:6035)

• Subclass deallocation of extern classes could crash if the base class uses GC.
  Original patch by Jason Fried. (Github issue :issue:5971)

• Type checks for Python memoryview could use an invalid C function.
  Patch by Xenia Lu. (Github issue :issue:5988)

• Calling final fused functions could generate invalid C code.
  (Github issue :issue:5989)

• Declaring extern enums multiple times could generate invalid C code.
  (Github issue :issue:5905)

• pyximport used relative paths incorrectly.
  Patch by Stefano Rivera. (Github issue :issue:5957)

• Running Cython with globbing characters ([]*?) in the module search path could fail.
  Patch by eewanco. (Github issue :issue:5942)

• Literal strings that include braces could change the C code indentation.

Other changes

• The "enum class not importable" warning is now only issued once per enum type.
  (Github issue :issue:5941)

v3.0.8

Compare Source

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

Bugs fixed

• Using const together with defined fused types could fail to compile.
  (Github issue :issue:5230)

• A "use after free" bug was fixed in parallel sections.
  (Github issue :issue:5922)

• Several types were not available as cython.* types in pure Python code.

• The generated code is now correct C89 again, removing some C++ style // comments
  and C99-style declaration-after-code code ordering. This is still relevant for some
  ols C compilers, specifically ones that match old Python 2.7 installations.

v3.0.7

Compare Source

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

Bugs fixed

• In the iterator of generator expressions, await and yield were not correctly analysed.
  (Github issue :issue:5851)

• cpdef enums with the same name cimported from different modules could lead to
  invalid C code.
  (Github issue :issue:5887)

• Some declarations in cpython.unicode were fixed and extended.
  (Github issue :issue:5902)

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

• Source files with non-ASCII file names could crash Cython.
  (Github issue :issue:5873)

• Includes all bug-fixes and features from the 0.29 maintenance branch
  up to the :ref:0.29.37 release.
