I started to put together a (long) list of changes between MooTools 1.1(1) and MooTools 1.2. Hopefully this will help people porting their script to the new MooTools version.
Personally I think that nothing beats spending an hour or two reading the new documentation but apparently some people don’t have the patience to do it! :P For those people, check it out, it’s still incomplete and it will probably take a while to cover everything but hey, it’s a start!
The list can be found here: http://silverscripting.wikidot.com/mootools-upgrade:from-1-1-to-1-2
It’s a wiki page so people can contribute to it too… (please do…)
