Version 3.3.1 is now available on the downloads page.
It contains the following bug fixes:
Fixed a bug that got introduced with the tooltips, where the Class Filter always shows "All".
The class filter worked, but it always displayed <<All>> as the selected option, this has been fixed.
Fixed a bug on the character statistics page, where sorting on "Int" didn't work.
Sorting on "Int" resulted in an empty screen, this has been fixed.
