The Bungee Blog

I finally find a moment to spread the good news: Tobie equipped Prototype with a deprecation/removal assistance layer. This extra deprecation.js file, to be loaded right after Prototype, spews clear, detailed, advise-replete messages in your Firebug console whenever your scripts use a now-removed or deprecated feature from earlier versions of the lib.

It’s a great help for migrating, and migrate you should. Get the whole details, usage recommendations, and grab the file on the relevant post at the Prototype Blog.
