The default way of navigating zoomed in submissions has changed, but the old can still be reverted to with a new settings option. The general settings have been prettied up somewhat. Other then that, there are many small tweaks/fixes. - Improved info box positioning in custom box tutorial. - Fixed gradients not overlapping correctly on tiled view of multi-file submissions. - Custom boxes may only shrink in height when the window is resized (to prevent their height from being animated using contained elements). - Custom box max height added (2000px). - Fixed audio file cover arts not showing. - Fixed random subject and random medium links. - Email sending fixed, emails prettied up with a new template. - Limit to how many emails your account may trigger in an hour added (15). - Themes are now account-bound (update your theme for the change to take effect). - Navigation and account display settings update without refreshing the page. - Changed default image zoom movement to work by mouse drag.
