- Core and Builtins
- gh-93351: 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.
- gh-94438: Fix an issue that caused extended opcode
arguments and some conditional pops to be ignored when
calculating valid jump targets for assignments to the
f_lineno attribute of frame objects. In some cases, this
could cause inconsistent internal state, resulting in a
hard crash of the interpreter.
- gh-95060: Undocumented PyCode_Addr2Location function now
properly returns when addrq argument is less than zero.
- gh-95113: Replace all EXTENDED_ARG_QUICK instructions
with basic EXTENDED_ARG instructions in unquickened
code. Consumers of non-adaptive bytecode should be able to
handle extended arguments the same way they were handled in
CPython 3.10 and older.
- gh-91409: Fix incorrect source location info caused by
certain optimizations in the bytecode compiler.
- gh-94036: Fix incorrect source location info for some
multi-line attribute accesses and method calls.
- gh-94739: Allow jumping within, out of, and across
exception handlers in the debugger.
- gh-94949: ast.parse() will no longer parse parenthesized
context managers when passed feature_version less than (3,
9). Patch by Shantanu Jain.
- gh-94947: ast.parse() will no longer parse assignment
expressions when passed feature_version less than (3,

- 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.
