Constraints
This directory holds the pip constraints used by the different testing environments used by Charmed OpenStack.
It's worth emphasize that these constraints are used for testing environments, that means used in tox.ini files, but never to build charms.
Naming scheme
The constraints files follow the following nomenclature:
constraints-$RELEASE.txt
$RELEASE represents the OpenStack release, with the special exception of
master that's used to apply constraints to the master and main branches.
For example for the case of OpenStack 2023.1 (Antelope), the constraints file
would be named constraints-2023.1.txt.
