* Fix a regression in 0.29.20 where __div__ failed to be found in extension types
* Fix a regression in 0.29.20 where a call inside of a finally clause could
fail to compile
* Zero-sized buffers could fail to validate as C/Fortran-contiguous.
* exec() did not allow recent Python syntax features in Py3.8+
due to https://bugs.python.org/issue35975
* Binding staticmethods of Cython functions were not behaving like
Python methods in Py3
* Pythran calls to NumPy methods no longer generate useless method lookup code.
* The PyUnicode_GET_LENGTH() macro was missing from the cpython.* declarations
* The deprecated PyUnicode_*() C-API functions are no longer used, except
for Unicode strings that contain lone surrogates. Unicode strings that
contain non-BMP characters or surrogate pairs now generate different C
code on 16-bit Python 2.x Unicode deployments (such as MS-Windows).
Generating the C code on Python 3.x is recommended in this case
* Some template parameters were missing from the C++ std::unordered_map declaration
* Several internal code generation issues regarding temporary variables were resolved

- Update to 0.29.20
* Nested try-except statements with multiple return statements
could crash due to incorrect deletion of the except as target variable.
* The @classmethod decorator no longer rejects unknown input from other decorators.
* Fused types could leak into unrelated usages. Patch by David Woods.
* Now uses Py_SET_SIZE() and Py_SET_REFCNT() in Py3.9+ to avoid
low-level write access to these object field
* The built-in abs() function could lead to undefined behaviour when used on
the negative-most value of a signed C integer type
* Usages of sizeof() and typeid() on uninitialised variables no longer produce a warning
* The C++ typeid() function was allowed in C mode
* The error position reported for errors found in f-strings was misleading
* The new c_api_binop_methods directive was added for forward compatibility,
but can only be set to True (the current default value). It can be disabled in Cython 3.0

- Update to 0.29.19
* Exception position reporting could run into race conditions on threaded code.
It now uses function-local variables again.
* Error handling early in the module init code could lead to a crash.
* Error handling in cython.array creation was improved to avoid calling C-API
functions with an error held.
* A memory corruption was fixed when garbage collection was triggered during
calls to PyType_Ready() of extension type subclasses. (Github issue #3603)
* Memory view slicing generated unused error handling code which could negatively
impact the C compiler optimisations for parallel OpenMP code etc.
Also, it is now helped by static branch hints. (Github issue #2987)
* Cython's built-in OpenMP functions were not translated inside of call arguments.
Original patch by Celelibi and David Woods. (Github issue #3594)
* Complex buffer item types of structs of arrays could fail to validate.
* Decorators were not allowed on nested async def functions.
* C-tuples could use invalid C struct casting. Patch by MegaIng.
* Optimised %d string formatting into f-strings failed on float values.
* Optimised aligned string formatting (%05s, %-5s) failed.
* Three missing timedelta access macros were added in cpython.datetime.
* The signature of the NumPy C-API function PyArray_SearchSorted() was fixed

Patch by David Woods. (Github issue #3370)
* C-tuples declared in ``.pxd`` files could generate incomplete C code.
Patch by Kirk Meyer. (Github issue #1427)

implemented functions.
Patch by David Woods. (Github issue #3384)

could fail with an exception.
Patch by David Woods. (Github issue #3433)

- Version update to 0.28.2
+ Features added
* ``abs()`` is faster for Python long objects.
* The C++11 methods ``front()`` and ``end()`` were added to the declaration of
``libcpp.string``. Patch by Alex Huszagh. (Github issue #2123)
* The C++11 methods ``reserve()`` and ``bucket_count()`` are declared for
``std::unordered_map``. Patch by Valentin Valls. (Github issue #2168)
+ Bugs fixed
* The copy of a read-only memoryview was considered read-only as well, whereas
a common reason to copy a read-only view is to make it writable. The result
of the copying is now a writable buffer by default.
(Github issue #2134)
* The ``switch`` statement generation failed to apply recursively to the body of
converted if-statements.
* ``NULL`` was sometimes rejected as exception return value when the returned
type is a fused pointer type.
Patch by Callie LeFave. (Github issue #2177)
* Fixed compatibility with PyPy 5.11.
Patch by Matti Picus. (Github issue #2165)
+ Other changes
* The NumPy tutorial was rewritten to use memoryviews instead of the older
buffer declaration syntax.

- Version update to 0.28.1:
* PyFrozenSet_New() was accidentally used in PyPy where it is lacking
from the C-API.
* Assignment between some C++ templated types were incorrectly rejected
when the templates mix const with ctypedef. (Github issue #2148)
* Undeclared C++ no-args constructors in subclasses could make the
compilation fail if the base class constructor was declared without
nogil. (Github issue #2157)
* Bytes %-formatting inferred basestring (bytes or unicode) as result type
in some cases where bytes would have been safe to infer. (Github issue #2153)
* None was accidentally disallowed as typed return value of dict.pop().
- update to version 0.28:
* Features added
+ Cdef classes can now multiply inherit from ordinary Python
classes. (The primary base must still be a c class, possibly
object, and the other bases must not be cdef classes.)
+ Type inference is now supported for Pythran compiled NumPy
expressions. Patch by Nils Braun. (Github issue #1954)
+ The const modifier can be applied to memoryview declarations to
allow read-only buffers as input. (Github issues #1605, #1869)
+ C code in the docstring of a cdef extern block is copied
verbatimly into the generated file. Patch by Jeroen
Demeyer. (Github issue #1915)
+ When compiling with gcc, the module init function is now tuned
for small code size instead of whatever compile flags were
provided externally. Cython now also disables some code
intensive optimisations in that function to further reduce the
code size. (Github issue #2102)
+ Decorating an async coroutine with @cython.iterable_coroutine
