Version 1.1 of LD50 is pending Apple's approval right now. It was submitted on Thursday the 19th, so I expect it to pop on the 24th or 25th. LD50 Lite was submitted about 12 hours after LD50, so it should be on a similar schedule.
The brief release notes:
Improved rendering performance.
Improved user-interface interactivity.
Improved computer opponent AI.
Added starry skybox.
Changed computer opponent animation.
Various minor bug fixes.
The ad hoc version for ibetatest.com beta testers is in the usual place.
Version 1.2 is under development and should follow in a week or so. Stay tuned to find out what's new in 1.2!
