Quite a milestone for Julia, and an important step forward towards stability as well: I believe a core Julia team member (Viral Shah IIRC) said that there would be only one or two major releases between 0.5 and 1.0.
One thing I like about Julia development is how receptive they are to community ideas, while also making sure the suggestions fit into the larger pattern and rejecting those that don't. (The "Support for arrays with indexing starting at values different from 1" thing does worry me, since it has the potential to screw things up gloriously, but it seems[1] they predicted HN will gnaw at this one. :) And I'm yet to read the whole of that issue, maybe it'll end up convincing me it's a good idea.)
