* Core and Builtins
- gh-119462: Make sure that invariants of type versioning are
maintained:
* Superclasses always have their version number assigned
before subclasses
* The version tag is always zero if the tag is not valid.
* The version tag is always non-zero if the tag is valid.
- gh-120437: Fix _CHECK_STACK_SPACE optimization problems
introduced in gh-118322.
- gh-120722: Correctly set the bytecode position on return
instructions within lambdas. Patch by Jelle Zijlstra.
- gh-120367: Fix bug where compiler creates a redundant
jump during pseudo-op replacement. Can only happen with
a synthetic AST that has a try on the same line as the
instruction following the exception handler.
- gh-113993: Strings interned with sys.intern() are again
garbage-collected when no longer used, as per the
documentation. Strings interned with the C function
PyUnicode_InternInPlace() are still immortal. Internals of
the string interning mechanism have been changed. This may
affect performance and identities of str objects.
- gh-120384: Fix an array out of bounds crash in
list_ass_subscript, which could be invoked via some
specificly tailored input: including concurrent
modification of a list object, where one thread assigns a
slice and another clears it.
- gh-120367: Fix crash in compiler on code with redundant
NOPs and JUMPs which show up after exception handlers are
moved to the end of the code.

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.
