- Update to 3.13.0:
Major new features of the 3.13 series, compared to 3.12
Some of the new major new features and changes in Python 3.13 are:
- New features
- A new and improved interactive interpreter, based on
PyPy's, featuring multi-line editing and color support, as
well as colorized exception tracebacks.
- An experimental free-threaded build mode, which disables
the Global Interpreter Lock, allowing threads to run
more concurrently. The build mode is available as an
experimental feature in the Windows and macOS installers as
well.
- A preliminary, experimental JIT, providing the ground work
for significant performance improvements.
- The locals() builtin function (and its C equivalent)
now has well-defined semantics when mutating the
returned mapping, which allows debuggers to operate more
consistently.
- A modified version of mimalloc is now included, optional
but enabled by default if supported by the platform, and
required for the free-threaded build mode.
- Docstrings now have their leading indentation stripped,
reducing memory use and the size of .pyc files. (Most tools
handling docstrings already strip leading indentation.)
- The dbm module has a new dbm.sqlite3 backend that is used
by default when creating new files.
- WASI is now a Tier 2 supported platform. Emscripten is
no longer an officially supported platform (but Pyodide
continues to support Emscripten).
- Typing
- Support for type defaults in type parameters.
- A new type narrowing annotation, typing.TypeIs.
- A new annotation for read-only items in TypeDicts.
- A new annotation for marking deprecations in the type
system.
- Removals and new deprecations
- PEP 594 (Removing dead batteries from the standard library)
scheduled removals of many deprecated modules: aifc,
audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib,
nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau,
telnetlib, uu, xdrlib, lib2to3.
- Many other removals of deprecated classes, functions and
methods in various standard library modules.
- C API removals and deprecations. (Some removals present
in alpha 1 were reverted in alpha 2, as the removals were
deemed too disruptive at this time.)
- New deprecations, most of which are scheduled for removal
from Python 3.15 or 3.16.
- For more details on the changes to Python 3.13, see What's
new in Python 3.13 in the documentation.

- Update to 3.13.0~rc3:
- The most important change is rolling back the incremental
cyclic garbage collector (GC), which was added in one of
the alpha releases. The incremental GC had more significant
performance regressions in specific workloads than we
expected.
- Tests
- gh-124378: Updated test_ttk to pass with Tcl/Tk 8.6.15.
- Library
- gh-124538: Fixed crash when using gc.get_referents() on a
capsule object.
- gh-124498: Fix typing.TypeAliasType not to be generic, when
type_params is an empty tuple.
- gh-123017: Due to unreliable results on some devices,
time.strftime() no longer accepts negative years on
Android.
- gh-123014: os.pidfd_open() and signal.pidfd_send_signal()
are now unavailable when building against Android API
levels older than 31, since the underlying system calls may
cause a crash.
- gh-124248: Fixed potential crash when using struct to
process zero-width ‘Pascal string’ fields (0p).
- gh-87041: Fix a bug in argparse where lengthy subparser
argument help is incorrectly indented.
- gh-124212: Fix invalid variable in venv handling of failed
symlink on Windows
- gh-124171: Add workaround for broken fmod() implementations
on Windows, that loose zero sign (e.g. fmod(-10, 1) returns
0.0). Patch by Sergey B Kirpichev.
- gh-123934: Fix unittest.mock.MagicMock reseting magic
methods return values after .reset_mock(return_value=True)
was called.
- gh-123968: Fix the command-line interface for the random
module to select floats between 0 and N, not 1 and N.
- gh-123892: Add "_wmi" to sys.stdlib_module_names. Patch by
Victor Stinner.
- gh-123339: Fix inspect.getsource() for classes
in collections.abc and decimal (for pure Python
implementation) modules. inspect.getcomments() now raises
OSError instead of IndexError if the __firstlineno__ value
for a class is out of bound.
- gh-121735: When working with zip archives,
importlib.resources now properly honors module-adjacent
references (e.g. files(pkg.mod) and not just files(pkg)).
- gh-122145: Fix an issue when reporting tracebacks
corresponding to Python code emitting an empty AST
body. Patch by Nikita Sobolev and Bénédikt Tran.
- gh-119004: Fix a crash in OrderedDict.__eq__ when operands
are mutated during the check. Patch by Bénédikt Tran.
- bpo-44864: Do not translate user-provided strings in
argparse.ArgumentParser.
- IDLE
- gh-112938: Fix uninteruptable hang when Shell gets rapid
continuous output.
- gh-120104: Fix padding in config and search dialog windows
in IDLE.
- Documentation
- gh-124720: Update “Using Python on a Mac” section of the
“Python Setup and Usage” document and include information
on installing free-threading support.
- gh-116622: Add an Android platform guide, and flag modules
not available on Android.
- Core and Builtins
- gh-124567: Revert the incremental GC (in 3.13), since it’s
not clear the benefits outweigh the costs at this point.
- gh-124642: Fixed scalability issue in free-threaded builds
for lock-free reads from dictionaries in multi-threaded
scenarios
- gh-116510: Fix a bug that can cause a crash when
sub-interpreters use “basic” single-phase extension
modules. Shared objects could refer to PyGC_Head nodes that
had been freed as part of interpreter cleanup.
- gh-124547: When deallocating an object with inline values
whose __dict__ is still live: if memory allocation for the
inline values fails, clear the dictionary. Prevents an
interpreter crash.
- gh-124513: Fix a crash in FrameLocalsProxy constructor:
check the number of arguments. Patch by Victor Stinner.
- gh-124442: Fix nondeterminism in compilation by sorting the
value of __static_attributes__. Patch by kp2pml30.
- gh-123856: Fix PyREPL failure when a keyboard interrupt is
triggered after using a history search
- gh-65961: Document the deprecation of setting and using
__package__ and __cached__.
- gh-124027: Support <page up>, <page down>, and <delete>
keys in the Python REPL when $TERM is set to vt100.
- gh-77894: Fix possible crash in the garbage collector when
it tries to break a reference loop containing a memoryview
object. Now a memoryview object can only be cleared if
there are no buffers that refer it.
- gh-123339: Setting the __module__ attribute for a class now
removes the __firstlineno__ item from the type’s dict, so
they will no longer be inconsistent.
- C API
- gh-124160: Fix crash when importing modules containing
state and single-phase initialization in a subinterpreter.
- gh-123880: Fixed a bug that prevented circular imports of
extension modules that use single-phase initialization.
- Build
- gh-124487: Windows builds now use Windows 8.1 as their API
baseline (installation already required Windows 8.1).
- gh-124043: Building using --with-trace-refs is
(temporarily) disallowed when the GIL is disabled.
- Remove upstreamed patch:
- gh-124040-fix-test-math-i586.patch
