latest upstream releases


As python2 is no longer supported


the package are updated to include postinstall script that
use "alternatives" to define for



a default to the highest package available.

$ alternatives --display python
python - status is auto.
  link currently points to /usr/bin/python3.9
/usr/bin/python2.7 - priority 27
/usr/bin/python3.6 - priority 36
/usr/bin/python3.7 - priority 37
/usr/bin/python3.8 - priority 38
/usr/bin/python3.9 - priority 39
Current `best' version is /usr/bin/python3.9.

The following link are not provided anymore.

In other systems as Debian
/usr/bin/python is discouraged.

As on Cygwin we have still several third packages depending on
python2, the usage of alternatives should allow to manage
until all are updated to python3

Python is a programming language that lets you work quickly
and integrate systems more effectively.
Python is powerful... and fast; plays well with others;
runs everywhere; is friendly & easy to learn; is Open.
