- Core and Builtins
- gh-109496: On a Python built in debug mode, Py_DECREF() now
calls _Py_NegativeRefcount() if the object is a dangling pointer
to deallocated memory: memory filled with 0xDD “dead byte” by
the debug hook on memory allocators. The fix is to check the
reference count before checking for _Py_IsImmortal(). Patch by
Victor Stinner.
- gh-109371: Deopted instructions correctly for tool
initialization and modified the incorrect assertion in
instrumentation, when a previous tool already sets INSTRUCTION
events
- gh-105658: Fix bug where the line trace of an except block
ending with a conditional includes an excess event with the line
of the conditional expression.
- gh-109219: Fix compiling type param scopes that use a name which
is also free in an inner scope.
- gh-109341: Fix crash when compiling an invalid AST involving a
ast.TypeAlias.
- gh-109195: Fix source location for the LOAD_* instruction
preceding a LOAD_SUPER_ATTR to load the super global (or
shadowing variable) so that it encompasses only the name super
and not the following parentheses.
- gh-109118: Disallow nested scopes (lambdas, generator
expressions, and comprehensions) within PEP 695 annotation
scopes that are nested within classes.
- gh-109114: Relax the detection of the error message for invalid
lambdas inside f-strings to not search for arbitrary replacement
fields to avoid false positives. Patch by Pablo Galindo
- gh-109118: Fix interpreter crash when a NameError is raised

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.
