Salstack version 3000.1 has been released on April 01, 2020. Please bump the version. It's important to ensure consistent minion/master versions, also on different systems (Windows, Debian, FreeBSD, ...). Reproducible: Always
For Python 3.7 as default target, salt-2019.2 is a blocker as it need Tornado <5 and Tornado:4.5.x depends on Python 3.6 But Salt-3000.1 works with Python < 3.8 and contains the needed Tornado code base https://docs.saltstack.com/en/latest/topics/releases/3000.html#vendored-tornado-code-base
I actually have python 3.6 as default target. However, since salt contains the required Tornado code base, it shouldn't be a blocker.
This was finished a little while ago.
