Guild Wars 2

So yesterday there were a patch or something. And i can’t find the changelog for that patch… Where can i find it? The only recent changelog is for 28th of January.
Reason for searching it is cause we did AC explorer path 1 and it was easy. Then patch came and when we came online again we did the 2nd path, which normally is easier (at least from my own experience) but yesterday it was hard for everyone and none of my party members had never had as much trouble as we did. Neither had I….

I bought this game recently and i find it very hard to get 4 people to do a dungeon story-mode with me. The reason for this, i think, is that everyone else have done the story-mode already and are doing the explorer-mode, cause they get something out of it.
So my suggestion is simple, add some sort of reward for doing the story-mode in a dungeon a second time, like half the price someone get for doing the explorer-mode.
I think that would increase the chances for low-level characters to do a dungeon story-mode.
