- Update to version 0.20:
* Support for CPython 3.4.
* Support for calling C++ template functions.
* yield is supported in finally clauses.
* The C code generated for finally blocks is duplicated for each exit
case to allow for better optimisations by the C compiler.
* Cython tries to undo the Python optimisationism of assigning a bound
method to a local variable when it can generate better code for the
direct call.
* Constant Python float values are cached.
* String equality comparisons can use faster type specific code in
more cases than before.
* String/Unicode formatting using the '%' operator uses a faster
C-API call.
* bytearray has become a known type and supports coercion from and
to C strings. Indexing, slicing and decoding is optimised. Note that
this may have an impact on existing code due to type inference.
* Using cdef basestring stringvar and function arguments typed as
basestring is now meaningful and allows assigning exactly
str and unicode objects, but no subtypes of these types.
* Support for the __debug__ builtin.
* Assertions in Cython compiled modules are disabled if the running
Python interpreter was started with the "-O" option.
* Some types that Cython provides internally, such as functions and
generators, are now shared across modules if more than one Cython
implemented module is imported.
* The type inference algorithm works more fine granular by taking the
results of the control flow analysis into account.
* A new script in bin/cythonize provides a command line frontend
to the cythonize() compilation function (including distutils build).

- update to 0.19.2:
* Some standard declarations were fixed or updated, including the previously
incorrect declaration of ``PyBuffer_FillInfo()`` and some missing bits in
``libc.math``.
* Heap allocated subtypes of ``type`` used the wrong base type struct at the
C level.
* Calling the unbound method dict.keys/value/items() in dict subtypes could
call the bound object method instead of the unbound supertype method.
* "yield" wasn't supported in "return" value expressions.
* Using the "bint" type in memory views lead to unexpected results.
It is now an error.
* Assignments to global/closure variables could catch them in an illegal state
while deallocating the old value. (forwarded request 204137 from dirkmueller)

- update to 0.19.1:
* Completely empty C-API structs for extension type slots (protocols like
number/mapping/sequence) are no longer generated into the C code.
* Docstrings that directly follow a public/readonly attribute declaration
in a cdef class will be used as docstring of the auto-generated property.
This fixes ticket 206.
* The automatic signature documentation tries to preserve more semantics
of default arguments and argument types. Specifically, ``bint`` arguments
now appear as type ``bool``.
* A warning is emitted when negative literal indices are found inside of
a code section that disables ``wraparound`` handling. This helps with
fixing invalid code that might fail in the face of future compiler
optimisations.
* Constant folding for boolean expressions (and/or) was improved.
* Added a build_dir option to cythonize() which allows one to place
the generated .c files outside the source tree.

- update to 3.2.2:
* The C-API declarations were updated to include the new
PyDict_*Ref() functions. (Github issue :issue:`7291`)
* 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`)
* Calling the unbound __mul__ special method of builtin
collections with subtypes failed. (Github issue
:issue:`7340`)
* C string literals could generate invalid "const to non-const"
casts in the C code. (Github issue :issue:`7346`)
* yield is no longer allowed inside of a
cython.critical_section, but is now allowed while holding a
cython.pymutex. (Github issue :issue:`7317`)
* Under lock congestion, acquiring the GIL could crash in
Python 3.11, part 2. This bug was introduced in Cython 3.2.0.
(Github issue :issue:`7312`)
* The new py_safe_* functions in libc.threads triggered C
compiler warnings. (Github issue :issue:`7356`)
* Cython now leaves markers about its utility code dependencies
in the generated C code to help debugging "unused function" C
compiler warnings. (Github issue :issue:`7294`)

used. This bug was introduced in Cython 3.2.0. (Github issue

were added.
* The monitoring code could crash on tracing.
* Initialising the monitoring code could fail with a CPython exception.
* Optimised integer shifting triggered undefined behaviour in C.
* Deallocating objects that inherit from external types defined in pxd files
could run into an infinite loop.
* A reference to metaclasses could be leaked on instantiation.
* (Unlikely) error handling during empty builtin container tests was ineffective.
* Generated *_api.h files used potentially unknown Cython configuration macros.
* cythonize() avoids parallel compiler runs on systems using spawn() in
multiprocessing.
* The @cython.ufunc decorator was missing in type checker stubs.
