Actually this dev build (well, the one released a couple of hours earlier than 3128) had a pretty major bug with gutter icons which broke text editing, scrolling etc. Thankfully it was fixed very quickly in 3128, and my experience with ST dev and beta builds is much the same as you, that's it's been very stable in general.
