* Cython generated incorrect self-casts when directly calling
final methods of subtypes.
* Internal C names generated from C function signatures could
become too long for MSVC.
* The noexcept warnings could be misleading in some cases.
* The @cython.ufunc implementation could generate incomplete C
code.
* The libcpp.complex declarations could result in incorrect C++
code. Patch by Raffi Enficiaud.
* Several tests were adapted to work with both NumPy 1.x and
2.0. Patch by Matti Picus.
* C compiler warnings when the freelist implementation is
disabled (e.g. on PyPy) were fixed. It can now be disabled
explicitly with the C macro guard CYTHON_USE_FREELISTS=0.
* Some C macro guards for feature flags were missing from the
NOGIL Python configuration.
* Some recently added builtins were unconditionally looked up
at module import time (if used by user code) that weren't
available on all Python versions and could thus fail the
import.
* A performance hint regarding exported pxd declarations was
improved.

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.
* Unused variable warnings about clineno were fixed when C
lines in tracebacks are disabled.
* Subclass deallocation of extern classes could crash if the
base class uses GC. Original patch by Jason Fried.
* Type checks for Python memoryview could use an invalid C
function. Patch by Xenia Lu.
* Calling final fused functions could generate invalid C code.
* Declaring extern enums multiple times could generate invalid
C code.
* pyximport used relative paths incorrectly. Patch by Stefano
Rivera.
* Running Cython with globbing characters ([]*?) in the module
search path could fail.
* Literal strings that include braces could change the C code

- update to version 3.0.4:
* Features added
- A new compiler directive show_performance_hints was added to
disable the newly added performance hint output. (Github issue
:issue:`5748`)
* Bugs fixed
- `cythonize` required ``distutils even for operations that did not
build binaries. (Github issue :issue:`5751`)
- A regression in 3.0.3 was fixed that prevented calling inline
functions from another inline function in .pxd files. (Github
issue :issue:`5748`)
- Some C compiler warnings were resolved. Patch by Pierre Jolivet.
(Github issue :issue:`5756`)
- update to version 3.0.3:
* Features added
- More warnings were added to help users migrate and avoid bugs.
(Github issue #5650)
- A warning-like category for performance hints was added that
bypasses -Werror. (Github issue #5673)
- FastGIL now uses standard thread_local in C++. (Github issue
#5640)
- reference_wrapper was added to libcpp.functional. Patch by Vyas
Ramasubramani. (Github issue #5671)
- The cythonize command now supports the --cplus option known from
the cython command. (Github issue #5736)
* Bug fixed
- Performance regressions where the GIL was needlessly acquired
were fixed. (Github issues #5670, #5700)
- A reference leak for exceptions in Python 3.12 was resolved.
Patch by Eric Johnson. (Github issue #5724)
- fastcall calls with keyword arguments generated incorrect C
code. (Github issue #5665)
- Assigning the type converted result of a conditional (if-else)
expression to int or bool variables could lead to incorrect C
code. (Github issue #5731)
- Early (unlikely) failures in Python function wrappers no longer
set a traceback in order to simplify the C code flow. Being
mostly memory allocation errors, they probably would never have
created a traceback anyway. (Github issue #5681)
- Relative cimports from packages with __init__.py files could
fail. (Github issue #5715)
- Several issues with the Limited API support were resolved.
(Github issues #5641, #5648, #5689)
- The code generated for special-casing both Cython functions and
PyCFunctions was cleaned up to avoid calling C-API functions
that were not meant for the other type respectively. This could
previously trigger assertions in CPython debug builds and now
also plays better with the Limited API. (Github issues #4804,
#5739)
- Fix some C compiler warnings. Patches by Ralf Gommers, Oleksandr
Pavlyk, Sebastian Koslowski et al. (Github issues #5651, #5663,
#5668, #5717, #5726, #5734)
- Generating gdb debugging information failed when using generator
expressions. Patch by Oleksandr Pavlyk. (Github issue #5552)
- Passing a setuptools.Extension into cythonize() instead of a
distutils.Extension could make it miss the matching extensions.
- cython -M needlessly required distutils, which made it fail in
Python 3.12. (Github issue #5681)
* Other changes
- The visible deprecation warning for DEF was removed again since
it proved difficult for some users to migrate away from it. The
statement is still meant to be removed at some point (and thus,
like IF, should not be used in new code), but the time for
sunset is probably not around the corner. (Github issue #4310)
- The np_pythran option raise a DeprecationWarning if it receives
other values than True and False. This will eventually be
disallowed (in line with all other boolean options).

- update to version 3.0.2:
* Bugs fixed
+ Using None as default value for arguments annotated as int could
crash Cython. (Github issue :issue:`5643`)
+ Default values of fused types that include complex could
generate invalid C code with -DCYTHON_CCOMPLEX=0. (Github issue
:issue:`5644`)
+ Using C++ enum class types in extension type method signatures
could generate invalid C code. (Github issue :issue:`5637`)
- changes from version 3.0.1:
* Features added
+ The error messages regarding exception declarations were
improved in order to give better help about possible reasons and
fixes. (Github issue :issue:`5547`)
* Bugs fixed
+ Memory view types in Python argument annotations no longer
accept None. They now require an explicit Optional[] or a None
default value in order to allow None to be passed. This was an
oversight in the 3.0.0 release and is a BACKWARDS INCOMPATIBLE
change. However, since it only applies to code using Python
syntax, it probably only applies to newly written code that was
written for Cython 3.0 and can easily be adapted. In most cases,
we expect that this change will avoid bugs in user code rather
than produce problems. (Github issue :issue:`5612`)
+ nogil functions using parallel code could freeze when called
with the GIL held. (Github issues :issue:`5564`, :issue:`5573`)
+ Relative cimports could end up searching globally and find the
same package installed elsewhere, potentially in another
version. (Github issue :issue:`5511`)
+ Attribute lookups on known standard library modules could
accidentally search in the module namespace instead. (Github
issue :issue:`5536`)
+ Using constructed C++ default arguments could generate invalid
C++ code. (Github issue :issue:`5553`)
+ libcpp.memory.make_unique() was lacking C++ exception
handling. (Github issue :issue:`5560`)
+ Some non-public and deprecated CAPI usages were replaced by
public (and thus more future proof) API code.
+ Many issues with the Limited API support were resolved. Patches
by Lisandro Dalcin et al. (Github issues :issue:`5549`,
:issue:`5550`, :issue:`5556`, :issue:`5605`, :issue:`5617`)
+ Some C compiler warnings were resolved. Patches by Matti Picus
et al. (Github issues :issue:`5557`, :issue:`5555`)
+ Large Python integers are now stored in hex instead of decimal
strings to work around security limits in Python and generally
speed up their Python object creation.
+ NULL could not be used as default for fused type pointer
arguments. (Github issue :issue:`5554`)
+ C functions that return pointer types now return NULL as default
exception value. Previously, calling code wasn't aware of this
and always tested for raised exceptions. (Github issue
:issue:`5554`)
+ Untyped literal default arguments in fused functions could
generate invalid C code. (Github issue :issue:`5614`)
+ C variables declared as const could generate invalid C code when
used in closures, generator expressions, ctuples, etc. (Github
issues :issue:`5558`, :issue:`5333`)
+ Enums could not refer to previously defined enums in their
definition. (Github issue :issue:`5602`)
+ The Python conversion code for anonymous C enums conflicted with
regular int conversion. (Github issue :issue:`5623`)
+ Using memory views for property methods (and other special
methods) could lead to refcounting problems. (Github issue
:issue:`5571`)
+ Star-imports could generate code that tried to assign to
constant C macros like PY_SSIZE_T_MAX and PY_SSIZE_T_MIN. Patch
by Philipp Wagner. (Github issue :issue:`5562`)
+ CYTHON_USE_TYPE_SPECS can now be (explicitly) enabled in PyPy.
+ The template parameter "delimeters" in the Tempita Template
class was corrected to "delimiters". The old spelling is still
available in the main template API but now issues a
DeprecationWarning. (Github issue :issue:`5608`)
+ The cython --version output is now less likely to reach both
stdout and stderr. Patch by Eli Schwartz. (Github issue
:issue:`5504`)
+ The sdist was missing the Shadow.pyi stub file.

- update to 0.29.33:
* 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.
* ``const`` fused types could not be used with memory views.
* ``wstr`` usage was removed in Python 3.12 and later (PEP-623).
* A type check assertion for Cython functions failed in debug Python
builds.
* Fixed various compiler warnings.
* Fixed error when calculating complex powers of negative numbers.
* Corrected a small mis-formatting of exception messages on Python 2.
* The ``PyUnicode_AsUTF8AndSize()`` C-API function was missing from the
CPython declarations.
* A performance problem in the compiler was resolved when nesting
conditional expressions.
* Test suite problems with recent NumPy and CPython versions were
resolved.
* 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.
* Properly disable generation of descriptor docstrings on PyPy since they
cause crashes.
It was previously disabled, but only accidentally via a typo.
* The ``cpow`` directive of Cython 3.0 is available as a no-op.

- update to 0.29.30:
* Avoid acquiring the GIL at the end of nogil functions. This change
was backported in order to avoid generating wrong C code that
would trigger C compiler warnings with tracing support enabled.
* Function definitions in finally: clauses were not correctly generated.
* A case where C-API functions could be called with a live exception
set was fixed.
* Cython now correctly generates Python methods for both the provided
regular and reversed special numeric methods of extension types.
* The C union type in pure Python mode mishandled some field names.

* Due to backwards incompatible changes in CPython 3.11a4, the feature flags
``CYTHON_FAST_THREAD_STATE`` and ``CYTHON_USE_EXC_INFO_STACK`` are now disabled
in Python 3.11 and later. They are enabled again in Cython 3.0.
Patch by David Woods. (Github issue #4610)
* A C compiler warning in older PyPy versions was resolved.
Patch by Matti Picus. (Github issue #4236)

- Make the running the test suite conditional (default
off). Seven hours of running it is just too much.
- Enable running of the test suite.
- update to 0.29.27:
* The ``cythonize`` command has a new option ``-M`` to generate ``.dep`` dependency
files for the compilation unit. This can be used by external build tools to track
these dependencies.
* Calls to ``range()`` with more than three arguments did not fail.
* Some C compiler warnings about missing type struct initialisers in Py3.10 were resolved.
* Cython no longer warns about using OpenMP 3.0 features since they are now
considered generally available.

- update to 0.29.25:
* Several incompatibilities with CPython 3.11 were resolved.
* Some C compiler warnings were resolved.
* C++ ``std::move()`` should only be used automatically in MSVC versions that support it.
* The ``Py_hash_t`` type failed to accept arbitrary "index" values.
* Avoid copying unaligned 16-bit values since some platforms require them to be aligned.
Use memcpy() instead to let the C compiler decide how to do it.
* Cython crashed on invalid truthiness tests on C++ types without ``operator bool``.
* The declaration of ``PyUnicode_CompareWithASCIIString()`` in ``cpython.unicode`` was incorrect.
