Growl has made its 2.0 SDK available, weeks after announcing that it planned to add a Notification Center action display to the program rather than letting it get Sherlocked by OS X Mountain Lion. The SDK also adds improvements to the Mist positioning system and various bugfixes.
The 2.0 SDK and the older 1.3.1 SDK are both available through Growl's downloads page.
