Finally! As most of you probably already know, Apple’s new version of their operating system Mac OS X ships on October 26th. For me it’s exciting news as a developer who uses Ruby on Rails, as Leopard is bundled with all needed tools for Rails development - Ruby on Rails, Capistrano and Mongrel. What is more, Ruby itself becomes a first-class citizen of scripting languages that you can use to write Cocoa applications for Mac OS X.

Xcode 3.0 and Objective-C 2.0 are coming too! I guess it’s high time to learn Cocoa and start developing native applications for Mac OS.

If you still don’t know what’s new in Leopard, here’s a list of 300 new features implemented. Give it a try, worth reading.
