You may notice a few consequential changes:
- The layout UI and rules for the panels have changed - you can now expand/collapse any of the sections - Styles, Search, Legend and Scroll - by clicking on the header.
- To implement efficiently required dropping support for IE6. Sorry, it's just not worth it.
- The JumpMap API now takes an optional border parameter which allows you to drop the border. This is used by the legend to render the images "live", matching your current style.
