Hi there - I'm completely biased of course, but I do believe that 2.0 even in it's current beta state is extremely stable, as witnessed by the fact people are using it currently in production. There are still some issues, which we are addressing now during the beta stage ahead of the general release, but I am confident that this will be the most stable version yet, with a ton more features,
If you or your instructor have specific concerns, please do fire them my way and I'll do all I can to try and address those,
All best,
