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.

And now for something completely different:
- Quark–gluon plasma (QGP) or quark soup is an interacting localized assembly of quarks and gluons at thermal and chemical equilibrium. The word plasma signals that free colour charges are allowed. In a 1987 summary, Léon van Hove pointed out the equivalence of the three terms: quark-gluon plasma, quark matter and a new state of matter. Since the temperature is above the Hagedorn temperature—and thus above the scale of light u,d-quark mass—the pressure exhibits the relativistic Stefan-Boltzmann format governed by temperature to the fourth power (T^4) and many practically massless quark and gluon constituents. It can be said that QGP emerges to be the new phase of strongly interacting matter which manifests its physical properties in terms of nearly free dynamics of practically massless gluons and quarks. Both quarks and gluons must be present in conditions near chemical equilibrium with their colour charge open for a new state of matter to be referred to as QGP.
- In the Big Bang theory, quark–gluon plasma filled the entire Universe before matter as we know it was created. Theories predicting the existence of quark–gluon plasma were developed in the late 1970s and early 1980s. Discussions around heavy ion experimentation followed suit and the first experiment proposals were put forward at CERN and BNL in the following years. Quark–gluon plasma was detected for the first time in the laboratory at CERN in the year 2000.
