The most important change is the enhanced points calculation for DLCs. Most of them were a bit underrated and this has been fixed. :) Don't worry, it's still the same algorithm and without going into details you should see a little point boost for your DLC achievements. Rankings should be a lot fairer by now. :)

Some other new features: You can now paste in any Steam profile URLs in the player search field. It doesn't matter if you copy the games, friends, badges or wishlist URLs, the search will sort it out for you.
Two new achievement listings have been added: Hardest and easiest beta achievements!
The crawler was updated, too - see my started topic in the discussions for details. ;)

Last but not least the Greek translation by Palpatine was added to the site. Thanks mate! :)
