The damage routine has been completely re-written behind-the-scenes.
This involved a significant amount of effort and time, but should lend
itself to a more streamlined and efficient damage function in the
future. While I tested this thoroughly, there may be a few errors which
have slipped through the cracks, so if you notice any bugs with damage
please file a bugreport.

More pertinent to you, however, the way that damage resistance is
calculated has been completely changed. It is now weighted, and each
buff is no longer applied individually (which allowed some obscene
damage resistance in certain cases - the highest I calculated was up to
175%). The helpfile HELP DMP has been introduced to explain this new
system.

There are a handful of exceptions to this new weighting system - mostly
those skills which are very limited in duration or have some kind of
constant drain asssociated with them.

Overall, it can be summarized thusly:
+ Those with very high damage resistance will notice a decrease
+ Those with low to moderate damage resistance will notice little to no
change
