What's new in this version:
- Add the Splitted property for the Dropdown control. This new property (which is also documented in the product help and has been added to the Editor Quick Code List) determines if the Dropdown control must appear split into two buttons or not. If the Dropdown control is split, then the control appears divided into two buttons, and the user must press the right one in order to open the associated menu. If the Dropdown is not split, then it looks like before this change, and, the user can just press the unique button in order to open the associated menu. There is a new Dropdown3 sample app that shows how to use the new Splitted property of the Dropdown control.

What's new in this version:
Security:
- Fixed an issue where instances of ssl.SSLSocket were vulnerable to a bypass of the TLS handshake and included protections (like certificate verification) and treating sent unencrypted data as if it were post-handshake TLS encrypted data
Core and Builtins:
- Fix potential unaligned memory access on C APIs involving returned sequences of char * pointers within the grp and socket modules. These were revealed using a - fsaniziter=alignment build on ARM macOS
- Ensure that multiprocessing synchronization objects created in a fork context are not sent to a different process created in a spawn context. This changes a segfault into an actionable RuntimeError in the parent process.
- Fix a segmentation fault caused by a use-after-free bug in frame_dealloc when the trashcan delays the deallocation of a PyFrameObject.
- No longer suppress arbitrary errors in the __annotations__ getter and setter in the type and module types.
- Propagate frozen_modules to multiprocessing spawned process interpreters.
- Fix crash in _imp.get_frozen_object() due to improper exception handling.
- Fix possible crashes when specializing function calls with too many __defaults__.
- Fix an issue that could result in crashes when compiling malformed ast nodes.
- Fix bugs in the builtins module where exceptions could end up being overwritten.
- Fix bug in the compiler where an exception could end up being overwritten.
- Improve error handling in PyUnicode_BuildEncodingMap() where an exception could end up being overwritten.
- Prevent out-of-bounds memory access during mmap.find() calls.
- Improve error handling when read marshal data.
Library:
- Harmonized the pure Python version of OrderedDict with the C version. Now, both versions set up their internal state in __new__. Formerly, the pure Python version did the set up in __init__.
- Fix multiprocessing.set_forkserver_preload() to check the given list of modules names
- Fixes os.path.normpath() to handle embedded null characters without truncating the path.
- tarfile.data_filter() now takes the location of symlinks into account when determining their target, so it will no longer reject some valid tarballs with LinkOutsideDestinationError.
- Fix doctest.DocTestFinder.find() in presence of class names with special characters
- Passing a callable object as an option value to a Tkinter image now raises the expected TclError instead of an AttributeError.
- Close asyncio.StreamWriter when it is not closed by application leading to memory leaks
- Seems that in some conditions, OpenSSL will return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL when a certification verification has failed, but the error parameters will still contain ERR_LIB_SSL and SSL_R_CERTIFICATE_VERIFY_FAILED. We are now detecting this situation and raising the appropiate ssl.SSLCertVerificationError
- tarfiles; Fixed use before assignment of self.exception for gzip decompression
- Make gettext.pgettext() search plural definitions when translation is not found.
- Document behavior of shutil.disk_usage() for non-mounted filesystems on Unix.
- Do not report MultipartInvariantViolationDefect defect when the email.parser.Parser class is used to parse emails with headersonly=True.
- Fix potential missing NULL check of d2i_SSL_SESSION result in _ssl.c.
- Update the bundled copy of pip to version 23.2.1.
- Fixed several bug in zipfile.Path in name/suffix/suffixes/stem operations when no filename is present and the Path is not at the root of the zipfile.
- Add __copy__ and __deepcopy__ in enum
- Revert a change to colorsys.rgb_to_hls() that caused division by zero for certain almost-white inputs
- re module: fix the matching of possessive quantifiers in the case of a subpattern containing backtracking
- Improve debug output for atomic groups in regular expressions
- Fix flag mask inversion when unnamed flags exist
-Prevent multiprocessing.spawn from failing to import in environments where sys.executable is None. This regressed in 3.11 with the addition of support for path-like objects in multiprocessing.
- Detect possible memory allocation failure in the libtommath function mp_init() used by the _tkinter module
- Make pydoc.doc catch bad module ImportError when output stream is not None
- Fix crash when calling repr with a manually constructed SignalDict object
- Fix a bug in _Unpickler_SetInputStream() where an exception could end up being overwritten in case of failure
- Fix bugs in sys where exceptions could end up being overwritten because of deferred error handling
- Harden pyexpat error handling during module initialisation to prevent exceptions from possibly being overwritten, and objects from being dereferenced twice
- Fix bug in decimal where an exception could end up being overwritten
- Fix bugs in _datetime where exceptions could be overwritten in case of module initialisation failure
- Fix bugs in _ssl initialisation which could lead to leaked references and overwritten exceptions
- Fix a bug in array.array where an exception could end up being overwritten
- Fix bugs in _ctypes where exceptions could end up being overwritten
- Fix a bug in the posix module where an exception could be overwritten
- Fix bugs in _elementtree where exceptions could be overwritten
- Fix bugs in zoneinfo where exceptions could be overwritten
- Fix bugs in pickle where exceptions could be overwritten
- Fix flag inversion when alias/mask members exist
- Fix bugs in pickle where exceptions could be overwritten
- Revert undocumented behaviour change with runtime-checkable protocols decorated with typing.final() in Python 3.11. The behaviour change had meant that objects would not be considered instances of these protocols at runtime unless they had a __final__ attribute
- Fix a bug in sqlite3 where an exception could be overwritten in the collation callback.
- Revert pickling method from by-name back to by-value.
- Add RTSPS scheme support in urllib.parse
- Fix a bug that causes wrong matches for regular expressions with possessive qualifier.
- Hide traceback in help() prompt, when import failed.
- Restore following CPython <= 3.10.5 behavior of shutil.make_archive(): do not create an empty archive if root_dir is not a directory, and, in that case, raise FileNotFoundError or NotADirectoryError regardless of format choice. Beyond the brought-back behavior, the function may now also raise these exceptions in dry_run mode.
- Fix hanging multiprocessing ProcessPoolExecutor when a child process crashes while data is being written in the call queue
- bpo-18319: Ensure gettext(msg) retrieve translations even if a plural form exists. In other words: gettext(msg) == ngettext(msg, '', 1).
Documentation:
- Document the curses module variables LINES and COLS
- Add a number of standard external names to nitpick_ignore
-Add documentation on how to localize the argparse module
Tests:
- Fix test_cppext when the C compiler command -std=c11 option: remove -std= options from the compiler command
- test_logging: Fix test_udp_reconnection() by increasing the timeout from 100 ms to 5 minutes (LONG_TIMEOUT)
- When running the Python test suite with -jN option, if a worker stdout cannot be decoded from the locale encoding report a failed testn so the exitcode is non-zero
Build:
- When calling find_python.bat with -q it did not properly silence the output of nuget. That is now fixed.
- Check for linux/limits.h before including it in Modules/posixmodule.c.
- Include commoninstall as a prerequisite for bininstall
- This ensures that commoninstall is completed before bininstall is started when parallel builds are used (make -j install), and so the python3 symlink is only installed after all standard library modules are installed.
- Allows -Wno-int-conversion for wasm-sdk 17 and onwards, thus enables building WASI builds once against the latest sdk
Windows:
- Fixes realpath() to behave consistently when passed a path containing an embedded null character on Windows. In strict mode, it now raises OSError instead of the unexpected ValueError, and in non-strict mode will make the path absolute.
- Fix integer overflow in _winapi.LCMapStringEx() which affects ntpath.normcase().
- Update Windows build to use OpenSSL 3.0.9
- Ensure that an empty environment block is terminated by two null characters, as is required by Windows.
macOS:
- Update macOS installer to use OpenSSL 3.0.10.
- Update macOS installer to use OpenSSL 3.0.9.
- Tools/Demos
- Update multissltests and GitHub CI workflows to use OpenSSL 1.1.1v, 3.0.10, and 3.1.2.
-Argument Clinic now supports overriding automatically generated signature by using directive @text_signature. See How to override the generated signature.
- Fix bugs in the Argument Clinic destination <name> clear command; the destination buffers would never be cleared, and the destination directive parser would simply continue to the fault handler after processing the command
C API:
- C API functions PyErr_SetFromErrnoWithFilename(), PyErr_SetExcFromWindowsErrWithFilename() and PyErr_SetFromWindowsErrWithFilename() save now the error code before calling PyUnicode_DecodeFSDefault()
- Such C API functions as PyErr_SetString(), PyErr_Format(), PyErr_SetFromErrnoWithFilename() and many others no longer crash or ignore errors if it failed to format the error message or decode the filename. Instead, they keep a corresponding error.
- PyModule_AddObjectRef() is now only available in the limited API version 3.10 or later.
- Fix a bug in PyErr_WarnExplicit() where an exception could end up being overwritten if the API failed internally.
- Fix PyUnicode_DecodeUTF8Stateful() for ASCII-only data: *consumed was not set
