We have released Adium 1.5.4. It features support for Mountain Lion’s Notification Center among other changes (full list).
Notification Center support
Adium 1.5.4 now supports Mountain Lion’s Notification Center. By default, notifications are shown for a couple of events. You can add and remove notifications in Adium’s “Events” preferences.
People have asked us how Adium decides between Notification Center and Growl (especially with Growl.app installed) so here is an explanation from our very own Stephen Holt:
1. Growl.app is installed, and the user has configured it to NOT use Notification Center:
Notifications work as before. Notification tickets are sent to Growl.app which performs actions and displays notifications as configured by the user
2. Growl.app is installed, and the user has configured it to use Notification Center:
Growl.framework detects this state from within the app and notifications are sent directly to NC. Additionally, notification tickets are sent to Growl which performs any associated actions. Growl.app displays nothing.
3. Growl.app is not installed:
Growl.framework detects this state from within the app and notifications are sent directly to NC. Nothing else is done.
Please note that only Growl.app version 2 or newer can be set to use Notification Center.
