We put the Growl 2.0 SDK out, adding support for Notification Center. (growl.posterous.com)

We put out the Growl 2.0 SDK, which is the first version to support Notification Center. Developers can drop the framework in place and gain Notification Center support in their applications that already have Growl implemented. Developers who support Growl in their new applications will get the benefits of Growl on 10.7 and 10.6, while on 10.8 getting NC or Growl depending on the scenario.
