Date: 2/27/2020
Chair: Ian
Minutes: Roland/Steve
Present: Roland, Steven, Peter, Liu, Ian, Bill, Zach, Maria, Yosef

updates on codes:
* Roland reminded reviewees to have their codes included in master
* had a discussion about whether it is worthwhile to delay releases if
   codes are not ready
* differing opinions on how much to strive for a 6 month release cycle
* requirement to go into master at this point is that including it must
   not fail
* presync: Steve should be able to get into master until Mar 1st
* delay self-force code: likely delay until next release
* simfactory python3: all clusters still offer python2, is default on
   most of them. May not want to do the hard switch. For simfactory3 the
   "sim" tool is python2 and has a rudimentary parser of the mdb and
   then looks for python3 (see
   Current python3 port of simfactory may be a bit more unstable due to
   python3's changed string handling. Solution is to check that the
   machine has locale set properly. Likely delay by one release.

timeline of ET release
* timeline is not objected by anyone on the call, including March 1 
cutoff for getting things into master
