From what I could see:
Strict enforcement of time limits. Judge has no discretion to allow competitor to continue the solve once the time limit has been reached.
Cumulative time limits are possible
Cumulative time penalties
0.00 on timer before end solve is an extra attempt (I think. I could be wrong on this one)
Outer Block Turn Metric instead of Half Term Metric.
Some organisational responsibilities have moved from organiser to delegate, although the delegate may delegate responsibilities to organisers.
In my opinion, the biggest thing changed is how we treat defective puzzles at the end of solves.
Also, main judge has been completely removed.
