Well, i got to say that the performance went down alot in the combat viewer.
Also there seem to be some major bugs. I mean, how can a fleet of 3 frigates with ca. 7 railguns each do the full 20 damage most of the thime when all my ships got 2 superior durantium systems with a combined power of 8?! it looks like defences do not work anymore or only block one weapon each, while rolling 0 most of the time...
