MacArthur was updated a few days ago (post below) and again today! These updates have all been related to Adium support. Adium made a major update to version 1.2 recently, and it broke a lot of things, including MacArthur. So I patched up a version that did as much as it could with 1.2, and gave up on the rest. This morning 1.2.1 was released, and it made integration possible again. It is nice when developers listen to requests :). So this update to MacArthur (version 3.7) brings everything back into alignment.
