Running OSX 10.8
After running the update the application seemed to eat up my CPU, not sure if this was 3rd party package related or what. After restarting again all was fine.
One bug that seems to have crept in:
show_quick_panel is now loosing focus when opened via a plugin.
Symptoms: if you type the first letter or two of the first item it will behave fine but anymore and it will loose focus and drop the cursor into the active view. If you type a letter that's not the first letter of the first item you'll automatically get sent to the active view.
