* Improved layout capabilities: Layouts components such as SplitPanes can now auto-size regions to the needs of their content. Percent and text-size relative positioning is supported throughout the framework. Using these capabilities, user interfaces can scale properly with changes in font size and/or display pixel density.
* Performance improvements, polish, cleanups, and testing: Echo3 is memory stable and responsive even in old browsers (IE6) on old hardware, and has generally matured since beta1.
