Yes, there will be a Dolphin Classic update before the Dolphin U final release. Quite a bit of work has already been done and a few more ideas, as well as critical issues are on the table.
Let me put this in perspective. In the last 14 months, you've closed about 30 tickets on the 7.1.5 milestone. There's about 80 tickets left. If you continue at that same rate, it will take another THREE YEARS to tend to all those issues. I don't know how you're going to do it with only two coders working on things, but you need to find a way.
We'll find a way. In long term two coders may actually produce a better result, without creating a whole new bunch of issues. The two we've got are the best there is.
