I just read, that the new prototype release is out by now – version 1.5. Since it was very hard to follow the development of prototype for quite a long time, the developer group made a complete rebirth for prototype. By now they provide a complete API documentation, some tutorials and whats left in the world of web 2.0? Of course, a blog.

To hava a closer look on what has changed go for the CHANGELOG.

Since prototype is the JavaScript framework of my choice, the only thing, that I can say is – check it out!
