- 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.

- Update to 3.11.0b5:
- 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,
8). Patch by Shantanu Jain.
- gh-91256: Ensures the program name is known for help text
during interpreter startup.
- gh-94869: Fix the column offsets for some expressions in
multi-line f-strings ast nodes. Patch by Pablo Galindo.
- gh-94822: Fix an issue where lookups of metaclass
descriptors may be ignored when an identically-named
attribute also exists on the class itself.
- gh-91153: Fix an issue where a bytearray item assignment
could crash if it’s resized by the new value’s __index__()
method.
- gh-90699: Fix reference counting bug in
bool.__repr__(). Patch by Kumar Aditya.
- Library
- gh-95087: Fix IndexError in parsing invalid date in the
email module.
- gh-95199: Upgrade bundled setuptools to 63.2.0.
- gh-95194: Upgrade bundled pip to 22.2.
- gh-95132: Fix a sqlite3 regression where *args and **kwds
were incorrectly relayed from connect() to the Connection
factory. The regression was introduced in 3.11a1 with PR
24421 (gh-85128). Patch by Erlend E. Aasland.`
- gh-93157: Fix fileinput module didn’t support errors option
when inplace is true.
- gh-95105: wsgiref.types.InputStream.__iter__() should
return Iterator[bytes], not Iterable[bytes]. Patch by
Shantanu Jain.
- gh-94857: Fix refleak in
_io.TextIOWrapper.reconfigure. Patch by Kumar Aditya.
- gh-94821: Fix binding of unix socket to empty address
on Linux to use an available address from the abstract
namespace, instead of “0”.
- gh-89988: Fix memory leak in pickle.Pickler when looking up
dispatch_table. Patch by Kumar Aditya.
- bpo-47025: Drop support for bytes on sys.path.
- Tests
- gh-95212: Make multiprocessing test case
test_shared_memory_recreate parallel-safe.
- Build
- gh-94847: Fixed _decimal module build issue on GCC when
compiling with LTO and pydebug. Debug builds no longer
force inlining of functions.
- gh-94841: Fix the possible performance regression of
PyObject_Free() compiled with MSVC version 1932.
- gh-94801: configure now uses custom flags like ZLIB_CFLAGS
and ZLIB_LIBS when searching for headers and libraries.
- gh-94773: deepfreeze.py now supports code object with
frozensets that contain incompatible, unsortable types.
- C API
- gh-94930: Fix SystemError raised when
PyArg_ParseTupleAndKeywords() is used with # in (...) but
without PY_SSIZE_T_CLEAN defined.
- gh-94864: Fix PyArg_Parse* with deprecated format units “u”
and “Z”. It returned 1 (success) when warnings are turned
into exceptions.
- gh-94731: Python again uses C-style casts for
most casting operations when compiled with
C++. This may trigger compiler warnings, if they
are enabled with e.g. -Wold-style-cast `` or
``-Wzero-as-null-pointer-constant options for g++.

- Update to 3.11.0b4:
- 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.
Tools/Demos
- gh-94538: Fix Argument Clinic output to custom file
destinations. Patch by Erlend E. Aasland.
C API
- gh-93937: The following frame functions and type are now
directly available with #include <Python.h>, it’s no longer
needed to add #include <frameobject.h>:
PyFrame_Check()
PyFrame_GetBack()
PyFrame_GetBuiltins()
PyFrame_GetGenerator()
PyFrame_GetGlobals()
PyFrame_GetLasti()
PyFrame_GetLocals()

- The Faster Cpython Project is already yielding some exciting
results. Python 3.11 is up to 10-60% faster than Python
3.10. On average, we measured a 1.22x speedup on the standard
benchmark suite. See
