[D][R]Recent developments in Reinforcement Learning

I am trying to get into reinforcement learning and have just finished the one by Sutton and Barto along with a course from YT. Just wanted to know what is currently being done on this topic(a survey paper/book will be nice). Also wanted to know what kind of datasets are commonly being used. The course I followed was completely theoretical in nature, so I also wanted to know what toolkit is used in this field currently .
