This is the Christmas release, which will be the last of the year.
It contains several bug fixes, but also shows the emphasize we are now putting on performance. The prebuilt release now includes minified versions of the JavaScript (dojo modules) and CSS files. More than that, thanks to the Dojo build system, the HTML templates are now compiled into the JavaScript files, resulting to less requests sent to the server. This is a great step forward!
Other optimizations for minimizing the downloads are also being worked out but they require some changes in the core XPages runtime, so they won't be available before the next release. Come and see us at Lotusphere for more details!
The dwa fragment had also been merged with the domino one. It doesn't change anything from a user standpoint but, if you're working with the source code, then you'll have to remove this fragment from your Eclipse workspace.
Enjoy the release, have a great holidays and merry Christmas!
