- Converting between int and str in bases other than 2
(binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base
10 (decimal) now raises a ValueError if the number of digits
in string form is above a limit to avoid potential denial of
service attacks due to the algorithmic complexity. This is
a mitigation for CVE-2020-10735.
This new limit can be configured or disabled by environment
variable, command line flag, or sys APIs. See the integer
string conversion length limitation documentation. The
default limit is 4300 digits in string form.
- Fix case of undefined behavior in ceval.c
- Do not expose KeyWrapper in _functools.
- Ensure that tracing, sys.setrace(), is turned on
immediately. In pre-release versions of 3.11, some tracing
events might have been lost when turning on tracing in a
__del__ method or interrupt.
- Fix use after free in trace refs build mode. Patch by Kumar
Aditya.
- When loading a file with invalid UTF-8 inside a multi-line
string, a correct SyntaxError is emitted.
- Make sure that incomplete frames do not show up in
tracemalloc traces.
- Remove two cases of undefined behavior, by adding NULL
checks.
- Fix possible NULL pointer dereference in
_PyThread_CurrentFrames. Patch by Kumar Aditya.
- Fix AttributeError missing name and obj attributes in
object.__getattribute__(). Patch by Philip Georgi.
- Loading a file with invalid UTF-8 will now report the broken

- Core and Builtins
- Update code object hashing and equality to consider all
debugging and exception handling tables. This fixes an
issue where certain non-identical code objects could be
“deduplicated” during compilation.
- _PyPegen_Parser_New now properly detects token memory
allocation errors. Patch by Honglin Zhu.
- Run Python code in tracer/profiler function at full
speed. Fixes slowdown in earlier versions of 3.11.
- Emit a warning in debug mode if an object does not call
PyObject_GC_UnTrack() before deallocation. Patch by Pablo
Galindo.
- Prevented crashes in the AST constructor when
compiling some absurdly long expressions like
"+0"*1000000. RecursionError is now raised instead. Patch
by Pablo Galindo
- ast.AST node positions are now validated when provided to
compile() and other related functions. If invalid positions
are detected, a ValueError will be raised.
- Fix error detection in some builtin functions when keyword
argument name is an instance of a str subclass with
overloaded __eq__ and __hash__. Previously it could cause
SystemError or other undesired behavior.
- Library
- Update bundled pip to 22.2.2.
- Fix asyncio.TaskGroup to propagate exception when
asyncio.CancelledError was replaced with another exception
by a context manger. Patch by Kumar Aditya and Guido van
Rossum.

- Fixes many bugs and adds following more significant changes
- Security
- gh-68966: The deprecated mailcap module now refuses to inject
Coreunsafe text (filenames, MIME types, parameters) into
shell Corecommands. Instead of using such text, it will
warn and act Coreas if a match was not found (or for test
commands, as if the Coretest failed). and Builtins
- gh-93516: Lazily create a table mapping bytecode offsets to
line numbers to speed up calculation of line numbers when
tracing.
- gh-93461: importlib.invalidate_caches() now drops entries
from sys.path_importer_cache with a relative path as
name. This solves a caching issue when a process changes its
current working directory.
- FileFinder no longer inserts a dot in the path, e.g.
/egg/./spam is now /egg/spam.
Library
- gh-93896: Fix asyncio.run() and
unittest.IsolatedAsyncioTestCase to always the set event loop
as it was done in Python 3.10 and earlier. Patch by Kumar
Aditya.
- gh-94101: Manual instantiation of ssl.SSLSession objects is
no longer allowed as it lead to misconfigured instances that
crashed the interpreter when attributes where accessed on
them.
- gh-83658: Make multiprocessing.Pool raise an exception if
maxtasksperchild is not None or a positive int.
- gh-61162: Clarify sqlite3 behavior when Using the connection
as a context manager.
