I was afraid this day would come. Adium 1.3 beta was just released and it seems that Xblaze no longer works with it. I’ve been doing some initial digging and from what I can see, some things have changed in the plugin architecture which breaks some things in XBlaze.
The advice I’ll give for now is to not upgrade to 1.3 just yet. I’ll see what I can do about getting a fix out soon.
