This is becoming very problematic for those of us who want to use Rust, but who aren't in a position to be constantly updating code we wrote last week so that it works with whatever changes were made to Rust this week. We really, really, really NEED a stable release of Rust. Earlier in 2014 we were hearing that we'd have it by the end of 2014. Earlier this month we were hearing that we'd have it by the end of March 2015. Now we hear it may be much later than that. It's not at all encouraging!
