Octopus 2.0 isn't just a couple of new features; it's practically a ground-up rewrite. Right now we're at a point where most of the functionality works fine, but there are some missing pieces (mostly around installation/configuration) and usability quirks, so we've been doing "hand-held" preview releases to a few users to start getting feedback.
Going forward, the roll out plan for 2.0 looks something like this:
Right now we're tidying up a few bugs to do a final hands-on preview release. Then we'll move to finishing any items needed for a private beta (beta 1).
Beta 2 will be the first public release, and by then we hope to have something that is ready for day-to-day use, even if there are a few small bugs and no migration tool. We'll give it some time to settle and mature and build a migration tool from 1.X before we declare it "production ready".
I'll leave you with a screenshot from the new Tentacle setup wizard:
