Every artifact now has an icon which shows it's fresh index. It's nothing new, it used to be on this website for a long time in a form o star rating, but it was confusing and I was thinking for a long time how to replace it with something more meaningful
Working on javalibs.com gives me an unique opportunity to have lots of data about all artifacts in database, so I can mine it for useful data. And the next batch has been released just now.
Last year I've introduced dependency chart for every artifact. And for the last few months I've been busy remaking it from scratch in order to make it even more useful.
