Xcode 4.3 Released

Wow! a lot of changes...<p><i>- The Xcode 4.3 Toolset Is Repackaged as a Single App</i><p><i>- Command-Line Tools Are Optional</i><p><i>- /Developer No Longer Exists</i><p><i>- Auto Layout Is Now the Default for All New Cocoa Projects</i>

It looks like command like tools are now an optional install. That should help resolve some of the Ruby on Rails issues for OSX and XCode 4.x.
