There's been a big update released (maybe two).
Just started playing again, having to still try and avoid most media on it to avoid too many spoilers, but at the same time, I hate running the risk of doing something completely daft and blowing the run (yet not knowing it for ages).
Enjoying it though, play a mission or two at a time, about to hit my first nest (should have done it earlier, run out of things to research).
Not got any new classes yet, but can see how combining assault and sniper is really powerful.
Watched a lot (a hell of a lot) of xcom rebalanced, so having to remind myself I can move after shooting, remembering to come out for a good angle, shoot, then retreat back to being completely out of sight when possible.
