- gh-131809: Update bundled libexpat to 2.7.1
- gh-131261: Upgrade to libexpat 2.7.0
- gh-105704: When using urllib.parse.urlsplit() and
urllib.parse.urlparse() host parsing would not reject domain
names containing square brackets ([ and ]). Square brackets
are only valid for IPv6 and IPvFuture hosts according to RFC
3986 Section 3.2.2 (bsc#1236705, CVE-2025-0938,
gh#python/cpython#105704).
- gh-121284: Fix bug in the folding of rfc2047 encoded-words
when flattening an email message using a modern email
policy. Previously when an encoded-word was too long for
a line, it would be decoded, split across lines, and
re-encoded. But commas and other special characters in the
original text could be left unencoded and unquoted. This
could theoretically be used to spoof header lines using a
carefully constructed encoded-word if the resulting rendered
email was transmitted or re-parsed.
- gh-119511: Fix a potential denial of service in the imaplib
module. When connecting to a malicious server, it could
cause an arbitrary amount of memory to be allocated. On many
systems this is harmless as unused virtual memory is only
a mapping, but if this hit a virtual address size limit
it could lead to a MemoryError or other process crash. On
unusual systems or builds where all allocated memory is
touched and backed by actual ram or storage it could’ve
consumed resources doing so until similarly crashing.
- gh-121277: Writers of CPython’s documentation can now use
next as the version for the versionchanged, versionadded,
deprecated directives.

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.
