- gh-137426: Remove the code deprecation of
importlib.abc.ResourceLoader. It is documented as
deprecated, but left for backwards compatibility with other
classes in importlib.abc.
- gh-137282: Fix tab completion and dir() on
concurrent.futures.
- gh-137257: Bump the version of pip bundled in ensurepip to
version 25.2
- gh-137226: Fix behavior of
annotationlib.ForwardRef.evaluate() when the type_params
parameter is passed and the name of a type param is also
present in an enclosing scope.
- gh-130522: Fix unraisable TypeError raised during
interpreter shutdown in the threading module.
- gh-137059: Fix handling of file URLs with a
Windows drive letter in the URL authority by
urllib.request.url2pathname(). This fixes a regression in
earlier pre-releases of Python 3.14.
- gh-130577: tarfile now validates archives to ensure member
offsets are non-negative. (Contributed by Alexander Enrique
Urieles Nieto in gh-130577; CVE-2025-8194, bsc#1247249).
- gh-135228: When dataclasses replaces a class with a slotted
dataclass, the original class can now be garbage collected
again. Earlier changes in Python 3.14 caused this class to
always remain in existence together with the replacement
class synthesized by dataclasses.

- Update to 3.14.0~rc3:
- Tools/Demos
- gh-137873: The iOS test runner has been simplified,
resolving some issues that have been observed using
the runner in GitHub Actions and Azure Pipelines test
environments.

- gh-135661: Fix CDATA section parsing in
html.parser.HTMLParser according to the HTML5 standard: ]
]> and ]] > no longer end the CDATA section. Add private
method _set_support_cdata() which can be used to specify
how to parse <[CDATA[ — as a CDATA section in foreign
content (SVG or MathML) or as a bogus comment in the HTML
namespace.
- Library
- gh-138998: Update bundled libexpat to 2.7.2
- gh-118803: Add back collections.abc.ByteString and
typing.ByteString. Both had been removed in prior alpha,
beta and release candidates for Python 3.14, but their
removal has now been postponed to Python 3.17.
- gh-137226: Fix typing.get_type_hints() calls on generic
typing.TypedDict classes defined with string annotations.
- gh-138804: Raise TypeError instead of AttributeError when
an argument of incorrect type is passed to shlex.quote().
This restores the behavior of the function prior to 3.14.
- gh-128636: Fix crash in PyREPL when os.environ is
overwritten with an invalid value for mac
- gh-138514: Raise ValueError when a multi-character string
is passed to the echo_char parameter of getpass.getpass().
Patch by Benjamin Johnson.
- gh-138515: email is added to Emscripten build.
- gh-99948: ctypes.util.find_library() now works in
Emscripten build.
- gh-138253: Add the block parameter in the put() and
get() methods of the concurrent.interpreters queues for
compatibility with the queue.Queue interface.
- gh-138133: Prevent infinite traceback loop when sending
CTRL^C to Python through strace.
- gh-134869: Fix an issue where pressing Ctrl+C during tab
completion in the REPL would leave the autocompletion menu
in a corrupted state.
- gh-90548: Fix musl detection for platform.libc_ver() on
Alpine Linux if compiled with –strip-all.
- gh-136134: SMTP.auth_cram_md5() now raises an SMTPException
instead of a ValueError if Python has been built without
MD5 support. In particular, SMTP clients will not attempt
to use this method even if the remote server is assumed to
support it. Patch by Bénédikt Tran.
- gh-136134: IMAP4.login_cram_md5 now raises an IMAP4.error
if CRAM-MD5 authentication is not supported. Patch by
Bénédikt Tran.
- gh-134953: Expand _colorize theme with keyword_constant and
implement in repl.
- Core and Builtins
- gh-71810: Raise OverflowError for (-1).to_bytes() for
signed conversions when bytes count is zero. Patch by
Sergey B Kirpichev.
- gh-138192: Fix contextvars initialization so that all
subinterpreters are assigned the MISSING value.
- gh-138479: Fix a crash when a generic object’s
__typing_subst__ returns an object that isn’t a tuple.
- gh-138372: Fix SyntaxWarning emitted for erroneous
subscript expressions involving template string literals.
Patch by Brian Schubert.
- gh-138318: The default REPL now avoids highlighting
built-in names (for instance set or format()) when they
are used as attribute names (for instance in value.set or
text.format).
- gh-138349: Fix crash in certain cases where a module
contains both a module-level annotation and a
comprehension.
- gh-137384: Fix a crash when using the warnings module in a
finalizer at shutdown. Patch by Kumar Aditya.
- gh-137883: Fix runaway recursion when calling a function
with keyword arguments.
- gh-137079: Fix keyword typo recognition when parsing files.
Patch by Pablo Galindo.
- gh-137728: Fix the JIT’s handling of many local variables.
This previously caused a segfault.
- gh-137576: Fix for incorrect source code being shown in
tracebacks from the Basic REPL when PYTHONSTARTUP is given.
Patch by Adam Hartz.
