* Features added
  * Custom buffer slot methods are now supported in the Limited C-API of
    Python 3.9+. Patch by Lisandro Dalcin. (Github issue :issue:`5422`)
  * The extern "C" and extern "C++" markers that Cython generates for public
    functions can now be controlled by setting the C macro CYTHON_EXTERN_C.
  * The Python int handling code was adapted to make use of the new PyLong
    internals in CPython 3.12. (Github issue :issue:`5353`)
  * Conversion of Python ints to C int128 is now always supported, although
    slow if dedicated C-API support is missing (_PyLong_AsByteArray()),
    specifically in the Limited C-API. (Github issue :issue:`5419`)
  * The exception handling code was adapted to CPython 3.12. (Github
    issue :issue:`5442`)
  * The dataclass implementation was adapted to support Python 3.12. (Github
    issue :issue:`5346`)
  * The normal @dataclasses.dataclass and @functools.total_ordering
    decorators can now be used on extension types. Using the corresponding
    @cython.* deorators with automatically turn a Python class into an
    extension type (no need for @cclass). (Github issue :issue:`5292`)
  * Multiplying a sequence by a C integer avoids creating an intermediate
    Python integer.
  * ctuples can now be assigned from arbitrary sequences, not just Python
    tuples.
  * A new directive embedsignature.format was added to select the format
    of the docstring embedded signatures between python, c and argument
    clinic. Patch by Lisandro Dalcin. (Github issue :issue:`5415`)
  * Some invalid directive usages are now detected and rejected, e.g. using
    @ccall together with @cfunc, and applying @cfunc to a @ufunc. Cython also
    warns now when a directive is applies needlessly. (Github issue
    :issue:`5399` et al.)

warns now when a directive is applies needlessly. (Github issue

* Unicode identifier names now allow all letters defined in CPython 3.12.
* Bugs fixed
* Some C compile failures in CPython 3.12.0a6/a7 were resolved.
* Cascaded comparisons between integer constants and Python types could
fail to compile. (Github issue :issue:`5354`)
* The internal macro __PYX_IS_UNSIGNED was accidentally duplicated in
beta 2 which lead to C compile errors. Patch by 0dminnimda. (Github
issue :issue:`5356`)
* Memoryviews with typedef item types could fail to match the non-typedef
item types. Patch by Yue Yang. (Github issue :issue:`5373`)
* Fused memory views could raise a TypeError instead of a ValueError on
creation. Patch by Matúš Valo. (Github issue :issue:`5401`)
* Cython could crash when finding import files with dots in their
names. Patch by Matúš Valo. (Github issue :issue:`5396`)
* Selecting a context manager in parentheses and then calling it directly
failed to parse. (Github issue :issue:`5403`)
* __qualname__ and __module__ were not available inside of class
bodies. (Github issue :issue:`4447`)
* noexcept was not automatically applied to function pointer attributes in
extern structs. Patch by Matúš Valo. (Github issue :issue:`5359`)
* Function signatures containing a type like tuple[()] could not be
printed. Patch by Lisandro Dalcin. (Github issue :issue:`5355`)
* Extension type hierarchies were generated in the wrong order, thus
leading to compile issues. Patch by Lisandro Dalcin. (Github issue
:issue:`5395`)
* Using the --working option could lead to sources not being found. Patch
by Lisandro Dalcin. (Github issue :issue:`5365`)
* Some C compiler warnings were resolved. Patches by Matt Tyson,
Lisandro Dalcin, Philipp Wagner, Matti Picus et al. (Github issues
:issue:`5417`, :issue:`5418`, :issue:`5421`, :issue:`5437`,
:issue:`5438`, :issue:`5443`)
* Includes all bug-fixes and features from the 0.29 maintenance branch up
to the :ref:`0.29.35` release.
* Other changes
* For-loops now release the internal reference to their list/tuple
iterable before instead of after the else: clause. This probably has no
practical impact. (Github issue :issue:`5347`)
* Simple tuple types like (int, int) are no longer accepted in Python
annotations and require the Python notation instead (e.g.
tuple[cython.int, cython.int]). (Github issue :issue:`5397`)
* The code except +nogil (declaring a C++ exception handler function
called nogil) is now rejected because it is almost certainly a typo
from except + nogil. (Github issue :issue:`5430`)
