- Update to 3.14.0~rc2:
- Library
- gh-137426: Remove the code deprecation of
importlib.abc.ResourceLoader. It is documented as
deprecated, but left for backwards compatibility with other
classes in importlib.abc.
- gh-137282: Fix tab completion and dir() on
concurrent.futures.
- gh-137257: Bump the version of pip bundled in ensurepip to
version 25.2
- gh-137226: Fix behavior of
annotationlib.ForwardRef.evaluate() when the type_params
parameter is passed and the name of a type param is also
present in an enclosing scope.
- gh-130522: Fix unraisable TypeError raised during
interpreter shutdown in the threading module.
- gh-137059: Fix handling of file URLs with a
Windows drive letter in the URL authority by
urllib.request.url2pathname(). This fixes a regression in
earlier pre-releases of Python 3.14.
- gh-130577: tarfile now validates archives to ensure member
offsets are non-negative. (Contributed by Alexander Enrique
Urieles Nieto in gh-130577; CVE-2025-8194, bsc#1247249).
- gh-135228: When dataclasses replaces a class with a slotted
dataclass, the original class can now be garbage collected
again. Earlier changes in Python 3.14 caused this class to
always remain in existence together with the replacement
class synthesized by dataclasses.
- Documentation
- gh-136155: We are now checking for fatal errors in EPUB
builds in CI.
- Core and Builtins
- gh-137400: Fix a crash in the free threading
build when disabling profiling or tracing across
all threads with PyEval_SetProfileAllThreads()
or PyEval_SetTraceAllThreads() or their Python
equivalents threading.settrace_all_threads() and
threading.setprofile_all_threads().
- gh-137314: Fixed a regression where raw f-strings
incorrectly interpreted escape sequences in format
specifications. Raw f-strings now properly preserve literal
backslashes in format specs, matching the behavior from
Python 3.11. For example, rf"{obj:\xFF}" now correctly
produces '\\xFF' instead of 'ÿ'. Patch by Pablo Galindo.
- gh-137308: A standalone docstring in a node body is
optimized as a pass statement to ensure that the node’s
body is never empty. There was a ValueError in compile()
otherwise.
- gh-137288: Fix bug where some bytecode instructions of a
boolean expression are not associated with the correct
exception handler.
- gh-134291: Remove some newer macOS API usage from the JIT
compiler in order to restore compatibility with older OSX
10.15 deployment targets.
- gh-131338: Disable computed stack limit checks on non-glibc
linux platforms to fix crashes on deep recursion.
- gh-136870: Fix data races while de-instrumenting bytecode
of code objects running concurrently in threads.
- C API
- gh-137573: Mark _PyOptimizer_Optimize as Py_NO_INLINE to
prevent stack overflow crashes on macOS.
- Build
- gh-132339: Add support for OpenSSL 3.5.
- Replaces upstreamed patches:
- CVE-2025-8194-tarfile-no-neg-offsets.patch

Python 3 in SUSE
==============
* Subpackages *
Python 3 is split into several subpackages, based on external dependencies.
The main package 'python3' has soft dependencies on all subpackages needed to
assemble the standard library; however, these might not all be installed by default.
If you attempt to import a module that is currently not installed, an ImportError is thrown,
with instructions to install the missing subpackage. Installing the subpackage might result
in installing libraries that the subpackage requires to function.
* ensurepip *
The 'ensurepip' module from Python 3 standard library (PEP 453) is supposed to deploy
a bundled copy of the pip installer. This makes no sense in a managed distribution like SUSE.
Instead, you need to install package 'python3-pip'. Usually this will be installed automatically
with 'python3'.
Using 'ensurepip' when pip is not installed will result in an ImportError with instructions
to install 'python3-pip'.
* Documentation *
You can find documentation in seprarate packages: python3-doc and
python3-doc-pdf. These contan following documents:
Tutorial, What's New in Python, Global Module Index, Library Reference,
Macintosh Module Reference, Installing Python Modules, Distributing Python
Modules, Language Reference, Extending and Embedding, Python/C API,
Documenting Python
The python3-doc package constains many text files from source tarball.
* Interactive mode *
Interactive mode is by default enhanced with of history and command completion.
If you don't like these features, you can unset the PYTHONSTARTUP variable
in your .profile or disable it system wide in /etc/profile.d/python.sh.
