Revert "Update latest release to 3.20.0 (#13962)"
Created by: dadlerj
This reverts commit 82b7370d6e909e502bd24c87d22fb8ecd5f70274.
I don't know for sure if this is the right call, but if the delay to the next release coming out will be >2 more hours or so (e.g. if it'll take until tomorrow) then I definitely think we should revert this. Admins are seeing alerts to upgrade.
