In March I posted that an authentication change to AIM might break Adium for that service. The date of change came and went though and Adium continued to work. Apparently, the app is able to work with the newer authentication methods. I guess only very old clients were affected.
In addition, and seemingly unrelated, Adium got its first update in quite a long time. Just a patch release with minor fixes, but that still shows signs of development activity.
So, Adium is not dead. Yay.
