In addition to the iOS 7, Apple TV and iTunes 11.1 betas issued earlier today, Apple has also updated the forthcoming Xcode 5, OS X Server and Remote Desktop betas for developers. The Xcode update (Developer Preview 4) fixes a number of crashing bugs and polishes up the interface, with OS X Server update (also at Developer Preview 4) offering much the same in the way of changes. Apple Remote Desktop 3.7 was also updated, but with no reported changes apart from a lack of any known major issues.
