Strangely - I thought that one over and was going to post a post about it (with thoughts of even going back to 12.x) and didn't, but concluded that version 13.x should be used for the next release, and be predominantly issue corrective & reputation restorative. Thus allowing the next major version 14.x to be New Feature focussed. I am reasonably sure that after the 13.5 release there will be some other minor incremental quick fixes (13.5.2 13.6 etc) -- and we should just allow 13 to soak up all of that - rather than allowing a series of legacy fixes to poison the well of version 14.
I also think it is important to get a fully-tested fix release out ASAP. Thus 13.5 can be released without too much fanfare, but equally positioned & promoted to demonstrate that Moho is back in safe hands.
This then allows the next feature-focussed major version 14.x to define the new era of great Moho software, with Sales & Marketing going into Overdrive.
