The latest release of MacRuby now works with Apple's recently released Xcode 4 development environment. Previous releases of the open source Ruby for Mac systems had worked with Xcode 3.2 but Xcode 4 was a radical reworking of the development environment which meant reworking the integration which allowed use of tools such as Interface Builder.

The 0.10 release is the first of a series of more frequent releases the development team are making as they progress to version 1.0. The developers are concentrating on stability. Other changes include support for the new Sandy Bridge based MacBook Pro's and fixes to the App Store submission code. The release notes cover all the other changes.

MacRuby is a deeply customised version of Ruby for the Mac environment with LLVM just-in-time compilation under the hood and a tight binding to the Mac environment such that it can easily and simply make use of Mac OS X features. MacRuby no longer supports 32-bit Intel systems and only works on 64-bit Mac OS X 10.6 systems. MacRuby 0.10 binary installer is available to download(direct download link) with source also available under the Ruby licence.
