what eth upgrades are currently being developed?

so, until the merge i was pretty informed on whats going on with eth, what features are they adding and what not but now after the merge there has been a radio silence and i have no idea whats going on with eth and its not as easy to find anything relevant nowadays unlike before. what are some bigger upgrades that are being worked on? is stuff like sharding still in production? i really gotta catch up on whats up with eth... thanks
