- Security
- Replaced usage of tempfile.mktemp() with TemporaryDirectory
to avoid a potential race condition.
- Add auditing events to the marshal module, and stop raising
code.__init__ events for every unmarshalled code object.
Directly instantiated code objects will continue to raise
an event, and audit event handlers should inspect or
collect the raw marshal data. This reduces a significant
performance overhead when loading from .pyc files.
- Made the internal putcmd function in smtplib sanitize input
for presence of \r and \n characters to avoid (unlikely)
command injection.
- Core and Builtins
- Fixed pickling of range iterators that iterated for over
2**32 times.
- Fix a race in WeakKeyDictionary, WeakValueDictionary and
WeakSet when two threads attempt to commit the last pending
removal. This fixes asyncio.create_task and fixes a data
loss in asyncio.run where shutdown_asyncgens is not run
- Fixed a corner case bug where the result of
float.fromhex('0x.8p-1074') was rounded the wrong way.
- Refine the syntax error for trailing commas in import
statements. Patch by Pablo Galindo.
- Restore behaviour of complex exponentiation with
integer-valued exponent of type float or complex.
- Correct the ast locations of f-strings with format specs
and repeated expressions. Patch by Pablo Galindo
- Use new trashcan macros (Py_TRASHCAN_BEGIN/END) in
frameobject.c instead of the old ones

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.
