Description
Support for python2 has been dropped. All modules that depend on python now require python 3, and calls out to python3 directly. Most users should not be impacted by this change, as almost all operating systems ship with python3 now.
Migration guide
If you are on a system where python3 is not available and you were relying on python, you will now need to install python3.
