    - gh-135034: Fixes multiple issues that allowed tarfile
      extraction filters (filter="data" and filter="tar") to be
      bypassed using crafted symlinks and hard links.
      Addresses CVE-2024-12718 (bsc#1244056), CVE-2025-4138
      (bsc#1244059), CVE-2025-4330 (bsc#1244060), and
      CVE-2025-4517 (bsc#1244032).
    - gh-133767: Fix use-after-free in the “unicode-escape”
      decoder with a non-“strict” error handler (CVE-2025-4516,
      bsc#1243273).
    - gh-128840: Short-circuit the processing of long IPv6
      addresses early in ipaddress to prevent excessive memory
      consumption and a minor denial-of-service.
  - Library
    - gh-134718: ast.dump() now only omits None and [] values if
      they are default values.
    - gh-128840: Fix parsing long IPv6 addresses with embedded
      IPv4 address.
    - gh-134696: Built-in HACL* and OpenSSL implementations of
      hash function constructors now correctly accept the same
      documented named arguments. For instance, md5() could be
      previously invoked as md5(data=data) or md5(string=string)
      depending on the underlying implementation but these calls
      were not compatible. Patch by Bénédikt Tran.
    - gh-134210: curses.window.getch() now correctly handles
      signals. Patch by Bénédikt Tran.
    - gh-80334: multiprocessing.freeze_support() now checks for
      work on any “spawn” start method platform rather than only
      on Windows.

work on any “spawn” start method platform rather than only
on Windows.
- gh-114177: Fix asyncio to not close subprocess pipes which
would otherwise error out when the event loop is already
closed.
- gh-134152: Fixed UnboundLocalError that could occur during
email header parsing if an expected trailing delimiter is
missing in some contexts.
- gh-62184: Remove import of C implementation of io.FileIO
from Python implementation which has its own implementation
- gh-133982: Emit RuntimeWarning in the Python implementation
of io when the file-like object is not closed explicitly in
the presence of multiple I/O layers.
- gh-133890: The tarfile module now handles
UnicodeEncodeError in the same way as OSError when cannot
extract a member.
- gh-134097: Fix interaction of the new REPL and -X
showrefcount command line option.
- gh-133889: The generated directory listing page in
http.server.SimpleHTTPRequestHandler now only shows the
decoded path component of the requested URL, and not the
query and fragment.
- gh-134098: Fix handling paths that end with
a percent-encoded slash (%2f or %2F) in
http.server.SimpleHTTPRequestHandler.
- gh-134062: ipaddress: fix collisions in __hash__() for
IPv4Network and IPv6Network objects.
- gh-133745: In 3.13.3 we accidentally changed the signature
of the asyncio create_task() family of methods and how it
calls a custom task factory in a backwards incompatible
way. Since some 3rd party libraries have already made
changes to work around the issue that might break if
we simply reverted the changes, we’re instead changing
things to be backwards compatible with 3.13.2 while still
supporting those workarounds for 3.13.3. In particular, the
special-casing of name and context is back (until 3.14) and
consequently eager tasks may still find that their name
hasn’t been set before they execute their first yielding
await.
- gh-71253: Raise ValueError in open() if opener returns a
negative file-descriptor in the Python implementation of io
to match the C implementation.
- gh-77057: Fix handling of invalid markup declarations in
html.parser.HTMLParser.
- gh-133489: random.getrandbits() can now generate more that
231 bits. random.randbytes() can now generate more that 256
MiB.
- gh-133290: Fix attribute caching issue when setting
ctypes._Pointer._type_ in the undocumented and deprecated
ctypes.SetPointerType() function and the undocumented
set_type() method.
- gh-132876: ldexp() on Windows doesn’t round subnormal
results before Windows 11, but should. Python’s
math.ldexp() wrapper now does round them, so results may
change slightly, in rare cases of very small results, on
Windows versions before 11.
- gh-133089: Use original timeout value for
subprocess.TimeoutExpired when the func subprocess.run()
is called with a timeout instead of sometimes a confusing
partial remaining time out value used internally on the
final wait().
- gh-133009: xml.etree.ElementTree: Fix a crash in
Element.__deepcopy__ when the element is concurrently
mutated. Patch by Bénédikt Tran.
- gh-132995: Bump the version of pip bundled in ensurepip to
version 25.1.1
- gh-132017: Fix error when pyrepl is suspended, then resumed
and terminated.
- gh-132673: Fix a crash when using _align_ = 0 and _fields_
= [] in a ctypes.Structure.
- gh-132527: Include the valid typecode ‘w’ in the error
message when an invalid typecode is passed to array.array.
- gh-132439: Fix PyREPL on Windows: characters entered via
AltGr are swallowed. Patch by Chris Eibl.
- gh-132429: Fix support of Bluetooth sockets on NetBSD and
DragonFly BSD.
- gh-132106: QueueListener.start now raises a RuntimeError if
the listener is already started.
- gh-132417: Fix a NULL pointer dereference when a C function
called using ctypes with restype py_object returns NULL.
- gh-132385: Fix instance error suggestions trigger potential
exceptions in object.__getattr__() in traceback.
- gh-132308: A traceback.TracebackException now correctly
renders the __context__ and __cause__ attributes from
falsey Exception, and the exceptions attribute from falsey
ExceptionGroup.
- gh-132250: Fixed the SystemError in cProfile when locating
the actual C function of a method raises an exception.
- gh-132063: Prevent exceptions that evaluate as
falsey (namely, when their __bool__ method returns
False or their __len__ method returns 0) from being
ignored by concurrent.futures.ProcessPoolExecutor and
concurrent.futures.ThreadPoolExecutor.
- gh-119605: Respect follow_wrapped for __init__() and
__new__() methods when getting the class signature for a
class with inspect.signature(). Preserve class signature
after wrapping with warnings.deprecated(). Patch by Xuehai
Pan.
- gh-91555: Ignore log messages generated during handling of
log messages, to avoid deadlock or infinite recursion.
- gh-131434: Improve error reporting for incorrect format in
time.strptime().
- gh-131127: Systems using LibreSSL now successfully build.
- gh-130999: Avoid exiting the new REPL and offer suggestions
even if there are non-string candidates when errors occur.
- gh-130941: Fix configparser.ConfigParser parsing empty
interpolation with allow_no_value set to True.
- gh-129098: Fix REPL traceback reporting when using
compile() with an inexisting file. Patch by Bénédikt Tran.
- gh-130631: http.cookiejar.join_header_words() is now more
similar to the original Perl version. It now quotes the
same set of characters and always quote values that end
with "\n".
- gh-129719: Fix missing socket.CAN_RAW_ERR_FILTER constant
in the socket module on Linux systems. It was missing since
Python 3.11.
- gh-124096: Turn on virtual terminal mode and enable
bracketed paste in REPL on Windows console. (If the
terminal does not support bracketed paste, enabling it does
nothing.)
- gh-122559: Remove __reduce__() and __reduce_ex__() methods
that always raise TypeError in the C implementation
of io.FileIO, io.BufferedReader, io.BufferedWriter
and io.BufferedRandom and replace them with default
__getstate__() methods that raise TypeError. This restores
fine details of behavior of Python 3.11 and older versions.
- gh-122179: hashlib.file_digest() now raises BlockingIOError
when no data is available during non-blocking I/O. Before,
it added spurious null bytes to the digest.
- gh-86155: html.parser.HTMLParser.close() no longer loses
data when the <script> tag is not closed. Patch by Waylan
Limberg.
- gh-69426: Fix html.parser.HTMLParser to not unescape
character entities in attribute values if they are followed
by an ASCII alphanumeric or an equals sign.
- bpo-44172: Keep a reference to original curses windows in
subwindows so that the original window does not get deleted
before subwindows.
- Tests
- gh-133744: Fix multiprocessing interrupt test. Add an event
to synchronize the parent process with the child process:
wait until the child process starts sleeping. Patch by
Victor Stinner.
- gh-133639: Fix
TestPyReplAutoindent.test_auto_indent_default() doesn’t run
input_code.
- gh-133131: The iOS testbed will now select the most
recently released “SE-class” device for testing if a device
isn’t explicitly specified.
- gh-109981: The test helper that counts the list of open
file descriptors now uses the optimised /dev/fd approach on
all Apple platforms, not just macOS. This avoids crashes
caused by guarded file descriptors.
- IDLE
- gh-112936: fix IDLE: no Shell menu item in single-process
mode.
- Documentation
- gh-107006: Move documentation and example code for
threading.local from its docstring to the official docs.
- Core and Builtins
- gh-134908: Fix crash when iterating over lines in a text
file on the free threaded build.
- gh-127682: No longer call __iter__ twice in list
comprehensions. This brings the behavior of list
comprehensions in line with other forms of iteration
- gh-134381: Fix RuntimeError when using a not-started
threading.Thread after calling os.fork()
- gh-128066: Fixes an edge case where PyREPL improperly threw
an error when Python is invoked on a read only filesystem
while trying to write history file entries.
- gh-134100: Fix a use-after-free bug that occurs when an
imported module isn’t in sys.modules after its initial
import. Patch by Nico-Posada.
- gh-133703: Fix hashtable in dict can be bigger than
intended in some situations.
- gh-132869: Fix crash in the free threading build when
accessing an object attribute that may be concurrently
inserted or deleted.
- gh-132762: fromkeys() no longer loops forever when adding
a small set of keys to a large base dict. Patch by Angela
Liss.
- gh-133543: Fix a possible memory leak that could occur when
directly accessing instance dictionaries (__dict__) that
later become part of a reference cycle.
- gh-133516: Raise ValueError when constants True, False or
None are used as an identifier after NFKC normalization.
- gh-133441: Fix crash upon setting an attribute with a dict
subclass. Patch by Victor Stinner.
- gh-132942: Fix two races in the type lookup cache. This
affected the free-threaded build and could cause crashes
(apparently quite difficult to trigger).
- gh-132713: Fix repr(list) race condition: hold a strong
reference to the item while calling repr(item). Patch by
Victor Stinner.
- gh-132747: Fix a crash when calling __get__() of a method
with a None second argument.
- gh-132542: Update Thread.native_id after fork(2) to ensure
accuracy. Patch by Noam Cohen.
- gh-124476: Fix decoding from the locale encoding in the
C.UTF-8 locale.
- gh-131927: Compiler warnings originating from the same
module and line number are now only emitted once, matching
the behaviour of warnings emitted from user code. This can
also be configured with warnings filters.
- gh-127682: No longer call __iter__ twice when creating and
executing a generator expression. Creating a generator
expression from a non-interable will raise only when the
generator expression is executed. This brings the behavior
of generator expressions in line with other generators.
- gh-131878: Handle uncaught exceptions in the main input
loop for the new REPL.
- gh-131878: Fix support of unicode characters with two or
more codepoints on Windows in the new REPL.
- gh-130804: Fix support of unicode characters on Windows in
the new REPL.
- gh-130070: Fixed an assertion error for exec() passed a
string source and a non-None closure. Patch by Bartosz
Sławecki.
- gh-129958: Fix a bug that was allowing newlines
inconsitently in format specifiers for single-quoted
f-strings. Patch by Pablo Galindo.
- C API
- gh-132909: Fix an overflow when handling the K format in
Py_BuildValue(). Patch by Bénédikt Tran.
- Remove upstreamed patches:
- CVE-2025-4516-DecodeError-handler.patch
- gh-132535-rsrc-warn-test_timeout.patch
