Get the newest (“final”) Prototype library by getting the latest Scriptaculous library.
The new stuff in Prototype 1.4 seems to be more stability fixes (extra checking before doing things), and a couple of Rubyisms: `Object.succ` means `this + 1`. `inspect()` to get a representation of an object or element.
And there seems to be more stuff in the dept. of positioning objects on-screen.
As well as new String stuff. `camelize()` (thisIsCamelCase, so you know what they mean by camels), `toQueryParams()`.
All in all: more goodness. Via: Audible Ajax podcast with Scriptaculous’ author
