Pool status display rewritten to span over several lines.
CD is short for coin difficulty (also known as network difficulty, I think).
Accepted and rejected numbers are now based on share difficulty rather than share count.
RTT is short for Round-Trip Time and measures the time it took to submit a share to the server.
DC lists the number of disconnects. Note that servers that aren't in use may report a lot of disconnects, since they do not implement a proper 90 second idle notification message.
