There is no Special:WikiActivity anymore on new wikis, you should use Special:Recentchanges instead. If you are not used to it, it may take time, but the Recent Changes has much more options.

There are no threads anymore, message walls and discussions are based on Feeds, which is a platform that looks a lot like twitter.

And the new editor is generally better, despite some yet unsolved bugs. Basically it's not so different, what exactly are you facing difficulties with?
