Version 1.6.3 contains a few important bug fixes regarding Badges, Coupons and Ranks but also include a few improvements.
As of version 1.6.3, you can now filter the log based on User ID (as before), Username or email address.
The transfer script has been re-written in an attempt to better handle forms that are inserted into custom pages like profiles.
Anyone using a language other then English should update to 1.6.3 since some translations causes scripts to fail. An example is those using French and the Badge add-on where the French translation causes the badge editing script to produce an error.
Finally a big thank you to everyone who took the time to report issues!
