Prototype, in case you don't know, is a fantastic javascript library that lays the foundation for all the hottest new UI trends on the web. I've been using it for over a year now and I have to say it may just be the greatest thing ever to happen to javascript.
Anyway...they've finally come out with a 1.5 release version. Oh, and they also have a shiny new website with official documentation...that last part just makes me feel all warm inside.
