V2 final and V2 Beta 13 were nearly identical, but there were some minor regressions in V2 final that didn't exist in Beta 13. I've been running 2.0 Beta 13 for years. There was a specific regression that I encountered regularly that was in 2.0 final that wasn't in 2.0 Beta 13.

Problem is, I don't remember what it was now, it's been so many years. I seem to vaguely remember it was in the tuner section, which I don't need any more, so maybe I should run 2.0 final.
