A new version of LDD (4.2.5) was released today, January 18th. I just downloaded it. As expected, the main difference to the previous version (4.1.8) is the removal of DbM and LEGO Universe. The DbM and Universe palettes have been replaced by a LDD palette and the Extended Mode palette. This means that there is no longer any need to manually activate Extended Mode - it's there out of the box.
There are no new features compared to the previous version. On the other hand, a huge amount of new bricks have been added, along with new decorations and several brick bug fixes. I got a mail from Martin over at the LDD team who has compiled a "What's new" list specially for us hardcore LDD users - thanks for that Martin - and here are some stats for 4.2.5 (brickset version 604):
New bricks:

Personally, I think it's great to see all the work that is going on with LDD behind the scenes at TLG. With this amount of new bricks and bug fixes, there seems no doubt that TLG is supporting LDD all the way.
