Growl 1.3.1

Update Available - A newer version of Growl is available online. Click here to download it right now. What's up with the latest Growl update? Apparently it costs money now? Not that $1.99 for this useful piece of software were too much, announcement about this change? Why not? Users are already upset about this change and I really fail to see why they did this w/o any prior notification.

For the brave and able, Growl 1.3.1 can still be built from source - good luck fighting all the build errors then :-\
