Make sure to finish your quests* as you will get a 3 brand new ones after the update. Your weekly wins will also reset, so if you need or want the XP for your Mastery Pass, finish them up before then as it won’t carry over.

*Worth noting that there is occasionally a glitch where the quests will get “stuck” right before the update, but still award gold. So they can be “completed” over and over again for extra gold. It’s happened at least twice so far, afaik (most recently with MOM). Up to you if that’s worth saving a quest or two and playing right before the update just in case.
