This is a major release that introduces significant changes in the platform's architecture. Instead of the monolithic structure of 7.0 and earlier releases, this version is based on a kernel (application server), an application layer, and a developer interface layer. An extensive cleanup of the code base and of the external libraries has also been completed. Finally, this release includes hundreds of enhancements, additions (including a WIKI feature), changes, and fixes.
