Over on the official forums, Patience has posted the patch notes for tomorrow's update:

Along with some back-end, server-side changes which are transparent to the players, the following changes have been made in the April 3rd patch:

• The issue of the fog-of-war reappearing on maps has been fixed!
• Players running Windows Vista should find performance and stability has increased and problems decreased. More fixes are in the works.
• More fixes to address memory leaks and crashes.
• Collection/Kill quests are now properly added to the Quest Tracker upon advancing.
• In 800x600 resolution, the Quest Log no longer appears offscreen.
• By popular request, Gondorians now have the option for grey eyes at character creation.
