Hi, It is a great pleasure to announce the immediate availability of MacRuby 0.3! Check it out while it's still hot! MacRuby is a version of Ruby 1.9, ported to run directly on top of Mac OS X core technologies such as the Objective-C common runtime and garbage collector, and the CoreFoundation framework. While still a work in progress, it is the goal of MacRuby to enable the creation of full-fledged Mac OS X applications which do not sacrifice performance in order to enjoy the benefits of using Ruby. You can learn more about MacRuby, and download a binary installer, from the website: http://macruby.org Or about this release more specifically, on our blog: http://www.macruby.org/post/macruby-03/ This is an important release. MacRuby now comes with a core library named HotCocoa, which simplifies Cocoa programming by using simple Ruby idioms. The dispatcher was rewritten to use the Objective-C runtime, which eliminates many ambiguities but also improves some performance. And finally, lots of bug fixes, and a better Cocoa and Ruby support! Enjoy, Laurent
