 {{{
 3.2.5 (2026-05-23)
 ==================

 Bugs fixed
 ----------

 * A compile failure was fixed when using the walrus operator inside of
 try-except.
   (Github issue :issue:`7462`)

 * Expressions with side-effects as object argument to ``isinstance()``
 could get
   evaluated multiple times, e.g. when they use the walrus operator.
   (Github issue :issue:`7670`)

 * Several problems generating the shared utility module were resolved,
 including
   a performance regression with memory views.
   (Github issues :issue:`7487`, :issue:`7497`, :issue:`7504`,
 :issue:`7558`)

 * Some GC and refcounting issues were resolved for Cython functions in the
 Limited API.
   (Github issue :issue:`7594`)

 * Refcounting errors and error handling issues were resolved in some rare
 error handling cases.
   (Github issues :issue:`7597`, :issue:`7599`, :issue:`7612`,
 :issue:`7673`)

 * Using ``cython.pymutex`` in an extension type with ``cdef`` methods
 generated
   invalid C code missing the required ``PyMutex`` declarations.
   (Github issue :issue:`6995`)

 * Calling ``.get_frame()`` on Cython coroutines could crash in
 freethreading Python.
   (Github issue :issue:`7632`)

 * The vectorcall protocol was not used correctly in ``.throw()`` of Cython
 coroutines
   when raising the exception only by type (without value or traceback).
   (Github issue :issue:`7677`)

 * A problem with cpdef enums in the Limited API of Python 3.11+ was
 resolved.
   (Github issue :issue:`7503`)

 * Unicode predicates like ``.isdigit()`` are now allowed to fail in the
 Limited API.
   (Github issue :issue:`7602`)

 * Conditional expressions mixing Python float and int object types could
 accidentally
   infer float as the common result type, instead of treating both
 independently.

 * Using ``sizeof()`` in the size declarations of ``extern`` arrays failed.
   (Github issue :issue:`7451`)

 * Enabling profiling generated invalid C code for non-Python return
 tuples.
   (Github issue :issue:`7580`)

 * ``abs()`` on C ``long long`` values could generate invalid C code.

 * When the ``CYTHON_AVOID_BORROWED_REFS`` C macro is enabled, e.g. in
 GraalPython,
   dict iteration could fail to compile.
   Patch by Michael Šimáček.  (Github issue :issue:`7631`)

 * A C compiler warning about unused functions was resolved.
   (Github issue :issue:`7560`)

 * The ``py_safe_call_once()`` C++ mutex helper function in
 ``libcpp.mutex``
   failed to compile.
   (Github issue :issue:`7585`)

 * The ``cpython.array`` declarations were adapted for Python 3.15.  Direct
 access
   to the C struct of the ``array.array`` data type might require user code
 changes.
   (Github issue :issue:`7659`)

 * Spaces in file paths written to the ``depfile`` were not escaped.
   Patch by Loïc Estève.  (Github issue :issue:`7423`)

 * Cython's cache failed to restore multi-file results.
   (Github issue :issue:`7559`)

 * Using Tempita from its command line failed with a name error.
   (Github issue :issue:`7567`)

 Other changes
 -------------

 * The known builtin types were updated for Py3.15.
