* there have been tons of bugfixes over the last two years ...
* Thanks go to Patrick Steinhardt (then at Aservo) for python3 updates
* Thanks go to Josef Moellers (working at SUSE Labs) for many CVE fixes
* and of course all the other patches that came in via github issues.
* I have cleaned up sources to only uses Python3 (as needed by 2020).
