4.5.8 (Nov 2007)

New features (Ajax)

Speed Improvements
Many changes were made to decrease the load time of XAP applications and increase the speed of databinding and table rendering, especially in Internet Explorer. Users can expect Nexaweb applications to run 10-15% faster in Firefox, 20-30% faster in Internet Explorer

Memory improvement
Many changes were made to eliminate memory leaks. In 4.5.7, users using IE6 could see as much as 20mb in residual memory allocation after leaving a Nexaweb application. This has been reduced to near zero levels.
