- Core and Builtins
- gh-93418: Fixed an assert where an f-string has an equal
sign ‘=’ following an expression, but there’s no trailing
brace. For example, f”{i=”.
- gh-91924: Fix __ltrace__ debug feature if the stdout
encoding is not UTF-8. Patch by Victor Stinner.
- gh-93061: Backward jumps after async for loops are no
longer given dubious line numbers.
- gh-93065: Fix contextvars HAMT implementation to handle
iteration over deep trees.
- The bug was discovered and fixed by Eli Libman. See
MagicStack/immutables#84 for more details.
- gh-92311: Fixed a bug where setting frame.f_lineno to jump
over a list comprehension could misbehave or crash.
- gh-92112: Fix crash triggered by an evil custom mro() on
a metaclass.
- gh-92036: Fix a crash in subinterpreters related to the
garbage collector. When a subinterpreter is deleted,
untrack all objects tracked by its GC. To prevent a crash
in deallocator functions expecting objects to be tracked by
the GC, leak a strong reference to these objects on
purpose, so they are never deleted and their deallocator
functions are not called. Patch by Victor Stinner.
- gh-91421: Fix a potential integer overflow in
_Py_DecodeUTF8Ex.
- bpo-47212: Raise IndentationError instead of SyntaxError
for a bare except with no following indent. Improve
SyntaxError locations for an un-parenthesized generator
used as arguments. Patch by Matthieu Dartiailh.

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.
