MacRuby was version 0.1 about 3 years ago. A lot happened since, and we expect the next release to be our 1.0 RC. For Cocoa development, it's very stable, we haven't received any critical bug report since at least 3 releases.
Ah. I read 0.10 and thought 0.1. It's a logical mistake to make since 0.1 is a number and is the same as 0.10, I know a lot of other people count releases the same way, but skipping 0.10 might be a bit helpful, or keeping to a strict 0-9 policy. I saw Linus got tired of the 2.6.39 counting and just skipped ahead to 3.0.
