Which versions of Xcode are not updated to take advantage of HiDPI/Retina displays? I've been looking over the release notes for Xcode and can't find one that says it's been enabled for HiDPI mode and the retina display MacBook Pro. By enabled, I mean that Xcode will run on the new retina hardware - not that you could make an app that will then work on Retina.

Either:


I missed it in reading the notes
All versions of Xcode on Lion already have this so it's not called out as new.
No versions (publicly available - not prerelease or NDA) yet support retina displays


Has anyone figured out which versions of Xcode do not support retina?
The current non-beta version of Xcode, 4.3.3 for Lion, works fine on a retina device but certain UI elements are not retina-enabled. Most notably the little "LCD" screen that sits in the top middle of the toolbar, it looks quite blurry on a retina MBP. Also the Play/Stop buttons, and many other UI elements. 

However the text used to render your code is crisp.
