Python
O módulo test.support foi realocado
In this release, the test.support
module was moved from python3-libs
to the python3-test
subpackage.
This change aims to discover what packages are dependent on test.support
and what parts of this module are useful, and could be moved to the standard library.
Python 2 support was dropped from Sphinx
The packages and sub-packages providing Python 2 support for Sphinx have been removed. See the System Utilities section for details.
Python means Python 3
In package and command names, Python
will mean Python 3
, that is, users installing and running Python
or Python
packages without specifying a version will get Python 3
. As a result, the name Python
will not refer to a software that will be unmaintained upstream for most of Fedora 31’s lifetime and retired from Fedora 32.
Notable new changes include:
-
Running python will run
python3
. -
Running pytest will run the
Python 3
version ofpytest
, and similarly forpydoc
,pylint
, and so on. -
The
dnf install python
will installPackage-x-generic-16.pngpython3
, and similarly for otherpython-*
provides, that is,dnf install python-requests
will installPackage-x-generic-16.pngpython3-requests
. -
Packages with
Python 3
modules will provide the unversionedpython-
name. -
The
/usr/bin/python
command will be a symbolic link to/usr/bin/python3
living in the Package-x-generic-16.pngpython-unversioned-command subpackage of Package-x-generic-16.pngpython3. -
Python
package maintainers need no change, but there are several exceptions, such as:-
Packages with ambiguous names.
-
Packages with ambiguous provides.
-
Packages with missing
%python_provide
. -
Packages with Python versioned commands and tools.
-
Packages that need unversioned
Python
to bePython 2
.
-
-
Custom scripts with python shebangs will invoke
Python 3
by default, whereas previosuly they invokedPython 2
by default.
The final upstream release of Python 2 is planned for January 2020. No further fixes will be made upstream. Most of Fedora 31’s lifetime is after that date. Python 2 will be maintained only by its Fedora maintainers.

Python 3.8 is now available
Version 3.8 of the Python programming language and interpreter is now available in Fedora. You can install it from the python38

Note that the Python stack still uses Python 3.7 by default.
Python 3.8 has also been released as an asynchronous update for Fedora 30 and 29.
