This is the Christmas release, which will be the last of the year.
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!
