The function now sets temporarily the LC_CTYPE locale to the locale
of the category that determines the requested value if the locales are
different and the resulting string is non-ASCII.
This temporary change affects other threads.
Instead of surprise crashes and memory corruption, we now hang threads that attempt to re-enter the Python interpreter after Python runtime finalization has started. These are typically daemon threads (our long standing mis-feature) but could also be threads spawned by extension modules that then try to call into Python. This marks the `PyThread_exit_thread` public C API as deprecated as there is no plausible safe way to accomplish that on any supported platform in the face of things like C++ code with finalizers anywhere on a thread's stack. Doing this was the least bad option.

This is actually an upstream problem in curses, and has been reported
to them already:
https://lists.gnu.org/archive/html/bug-ncurses/2024-09/msg00101.html
This is a nice workaround in the meantime to prevent the segfault.

Resolve a memory leak introduced in CPython 3.10's :mod:`ssl` when the :attr:`ssl.SSLSocket.session` property was accessed. Speeds up read and write access to said property by no longer unnecessarily cloning session objects via serialization.

Instead of be limited just by the size of addressable memory (2**63
bytes), Python integers are now also limited by the number of bits, so
the number of bit now always fit in a 64-bit integer.
Both limits are much larger than what might be available in practice,
so it doesn't affect users.
_PyLong_NumBits() and _PyLong_Frexp() are now always successful.
* The module state now stores a strong reference to the Placeholder
singleton.
* Use a regular dealloc function.
* Add Py_TPFLAGS_HAVE_GC flag and a traverse function to help the GC
to collect the type when a _functools extension is unloaded.
* Add NEWS.d entry
* Allow ISO-8601 24:00 alternative to midnight on datetime.time.fromisoformat()
* Allow ISO-8601 24:00 alternative to midnight on datetime.datetime.fromisoformat()
* Add NEWS.d entry
* Improve error message when hour is 24 and minute/second/microsecond is not 0
* Add tests for 24:00 fromisoformat
* Remove duplicate call to days_in_month() by storing in variable
* Add Python implementation
* Fix Lint
* Fix differing error msg in datetime.fromisoformat implementations when 24hrs has non-zero time component(s)
* Fix using time components inside tzinfo in Python implementation
* Don't parse tzinfo in C implementation when invalid iso midnight
* Remove duplicated variable in datetime test assertion line
* Add self to acknowledgements
* Remove duplicate NEWS entry
* Linting
* Add missing test case for when wrapping the year makes it invalid (too large)
Use a `_PyStackRef` and defer the reference to `f_funcobj` when
possible. This avoids some reference count contention in the common case
of executing the same code object from multiple threads concurrently in
the free-threaded build.
- If setting `_fields_` fails, e.g. with AttributeError, don't set the attribute in `__dict__`
- Document the “finalization” behaviour
- Beef up tests: add `getattr`, test Union as well as Structure
- Put common functionality in a common function

Multiple places in the I/O stack optimize common cases by using the
information from stat. Currently individual members are extracted from
the stat and stored into the fileio struct. Refactor the code to store
the whole stat struct instead.
Parallels the changes to _io. The `stat` Python object doesn't allow
changing members, so rather than modifying estimated_size, just clear
the value.
