It's been a while

So I haven't played this game in a very long time because of phone space issues but I am now back into it. I didn't see a daily questions thread or anything so I hope it's ok to make this thread.

Starting up the game I've noticed quite a few changes to the menus and everything but how exactly has the game changed. Last I played was when Lyra was released so yeah can someone just post a rundown of all the important changes since then (or a link I might have missed that highlights those changes) like is the lane meta still to have the roam with the jungle or has that finally changed? Any new game changing items or anything? I did play some of the brawl games which seem to be more of the focus now than the traditional moba game mode but yeah what have I missed?
