MacRuby 0.6 is now available.

With this release, the MacRuby team deem version 0.6 to be stable enough to use in the development of Cocoa applications. Also new in MacRuby 0.6 is experimental support for C extensions written for MRI, a new string class that supports the Ruby 1.9 encoding semantic, and honours insertion ordering. Experimental support for debugging is also available in this release. In addition, there are also many bug fixes, which are viewable at the Release Notes.
