Python (64-bit)

What's new in this version:

Core and Builtins:
-Fix the defs and kwdefs arguments to PyEval_EvalCodeEx() and a reference leak in that function
- Fix wrong lineno in exception message on continue or break which are not in a loop. Patch by Dong-hee Na
- Fix is_normalized() to properly handle the UCD 3.2.0 cases. Patch by Dong-hee Na
- Fix a possible memory leak in the parser when raising MemoryError. Patch by Pablo Galindo
- Fix potential memory underallocation issue for instances of int subclasses with value zero
- Fixed segfault in property.getter/setter/deleter that occurred when a property subclass overrode the __new__ method to return a non-property instance
- Fix race while iterating over thread states in clearing threading.local. Patch by Kumar Aditya
- Fix misleading default value in input()’s __text_signature__
- Fix int.__sizeof__() calculation to include the 1 element ob_digit array for 0 and False
- Update the native_thread_id field of PyThreadState after fork
- Fix incorrect result and delay in socket.getfqdn(). Patch by Dominic Socular
-Initialize frame->previous in frameobject.c to fix a segmentation fault when accessing frames created by PyFrame_New()
- Honor existing errors obtained when searching for mismatching parentheses in the tokenizer. Patch by Pablo Galindo
- bpo-32782: ctypes arrays of length 0 now report a correct itemsize when a memoryview is constructed from them, rather than always giving a value of 0.

Library:
- [Enum] - fix psuedo-flag creation
- Fix regression when passing None as second or third argument to FutureIter.throw.
- Avoid potential unexpected freeaddrinfo call (double free) in socket when when a libc getaddrinfo() implementation leaves garbage in an output pointer when returning an error. Original patch by Sergey G. Brester.
- Remove unused references to TimerHandle in asyncio.base_events.BaseEventLoop._add_callback.
- Make zipfile.Path.open() and zipfile.Path.read_text() also accept encoding as a positional argument. This was the behavior in Python 3.9 and earlier. 3.10 introduced a regression where supplying it as a positional argument would lead to a TypeError.
- Fix typing.get_type_hints() on '*tuple[...]' and *tuple[...]. It must not drop the Unpack part.
- Fix a Windows asyncio bug with named pipes where a client doing os.stat() on the pipe would cause an error in the server that disabled serving future requests
- Modify random.choice() implementation to once again work with NumPy arrays
-Avoid RecursionError on repr if a dataclass field definition has a cyclic reference
- pass encoding kwarg to subprocess in platform
- Fix crash in pyexpat by statically allocating PyExpat_CAPI capsule
- Fix unittest.mock.Mock not respecting the spec for attribute names prefixed with assert
-Fix asyncio.open_connection() to skip binding to local addresses of different family. Patch by Kumar Aditya
- Fix the interaction of unittest.mock.seal() with unittest.mock.AsyncMock
- http.server now checks that an index page is actually a regular file before trying to serve it. This avoids issues with directories named index.html.
- Remove any deprecation warnings in asyncio.get_event_loop(). They are deferred to Python 3.12.
-Fix handling of partial and invalid UNC drives in ntpath.splitdrive(), and in ntpath.normpath() on non-Windows systems. Paths such as ‘server’ and ‘’ are now considered by splitdrive() to contain only a drive, and consequently are not modified by normpath() on non-Windows systems. The behaviour of normpath() on Windows systems is unaffected, as native OS APIs are used. Patch by Eryk Sun, with contributions by Barney Gale.
-Fix crash when creating an instance of _ctypes.CField.
-Fix a reference undercounting issue in ctypes.Structure with from_param() results larger than a C pointer
- Fix regression in asyncio where a subprocess would sometimes lose data received from pipe
- Fix tuple subclasses being cast to tuple when used as enum values
-Update HTTPError to be initialized properly, even if the fp is None. Patch by Dong-hee Na
-Fix inspect.getsource() handling of decorator calls with nested parentheses
-Fix .save() method for LWPCookieJar and MozillaCookieJar: saved file was not truncated on repeated save
-Fix doctest failure on types.MethodWrapperType in modules
-Fix double-free bug in Argument Clinic str_converter by extracting memory clean up to a new post_parsing section
-Fix refcount error when arguments are packed to tuple in Argument Clinic
-Several improvements to inspect.signature()’s handling of __text_signature. - Fixes a case where inspect.signature() dropped parameters - Fixes a case where inspect.signature() raised tokenize.TokenError - Allows inspect.signature() to understand defaults involving binary operations of constants - inspect.signature() is documented as only raising TypeError or ValueError, but sometimes raised RuntimeError. These cases now raise ValueError - Removed a dead code path
-Fix a 3.11 regression in asynccontextmanager(), which caused it to propagate exceptions with incorrect tracebacks and fix a 3.11 regression in contextmanager(), which caused it to propagate exceptions with incorrect tracebacks for StopIteration.
- bpo-44817: Ignore WinError 53 (ERROR_BAD_NETPATH), 65 (ERROR_NETWORK_ACCESS_DENIED) and 161 (ERROR_BAD_PATHNAME) when using ntpath.realpath()
- bpo-40447: Accept os.PathLike (such as pathlib.Path) in the stripdir arguments of compileall.compile_file() and compileall.compile_dir()
- bpo-36880: Fix a reference counting issue when a ctypes callback with return type py_object returns None, which could cause crashes

Documentation:
- Document existing attr parameter to curses.window.vline() function in curses
- Remove claim in documentation that the stripdir, prependdir and limit_sl_dest parameters of compileall.compile_dir() and compileall.compile_file() could be bytes.
-Use sphinxext-opengraph to generate OpenGraph metadata

Tests:
- test_tarfile has been updated to pass when run as a high UID
- Start running SSL tests with OpenSSL 3.1.0-beta1
- Add functional test for Argument Clinic

Build:
- Allow overriding Windows dependencies versions and paths using MSBuild properties

Windows:
- Ensure the install path in the registry is only used when the standard library hasn’t been located in any other way.
- The py.exe launcher now correctly filters when only a single runtime is installed. It also correctly handles prefix matches on tags so that -3.1 does not match 3.11, but would still match 3.1-32.
- Restore ability to launch older 32-bit versions from the py.exe launcher when both 32-bit and 64-bit installs of the same version are available.
-Fixed an issue where writing more than 32K of Unicode output to the console screen in one go can result in mojibake.
- Ensures the PythonPath registry key from an install is used when launching from a different copy of Python that relies on an existing install to provide a copy of its modules and standard library.
- Restores support for the py.exe launcher finding shebang commands in its configuration file using the full command name.
- Update Windows installer to OpenSSL 1.1.1s
- bpo-43984: winreg.SetValueEx() now leaves the target value untouched in the case of conversion errors. Previously, -1 would be written in case of such errors.
