Here is where we currently are in the release process. Current step in bold.

Release Precursor Steps

  1. Identify any pre-release blockers (“must-have features”)
    Contributors check if there are outstanding issues that have to be included in the next release and relate them as blocker to the issue DM-20564.
  2. Wait until all blocking issues are resolved.
  3. Create Jira issues for each release activity.
  4. Check that the weekly build is scientifically suitable to be used as the starting point for the release (w_2020_22)

Release Jira issue: https://jira.lsstcorp.org/browse/DM-20564
Weekly used as the starting point for the release is w_2020_22

The tentative target date to close the release is 2020-06-21 (instead of May 29th).

I have used the v20.0.0.rc1 release candidate in a few test on different platforms, without problems.
Everybody is invited to try it out (this was implicit, announcing that the rc1 is available, but better to state it explicitly).
