Good news all the way around with the new Mootools release. First off Mootools is showing off its fast new selector engine Slick. Second, Moopromptu (the mootools version of Impromptu) works with the new release! Recently I also moved Moopromptu over to Forge, so you can check it out there.
My thoughts on the new release is one of hope. I hope all the changes have been made as far as depreciating methods from here on. Its difficult to maintain code with methods becoming obsolete. That being said I like their decisions to drop the $extend type functions and move to a more object based convention. Anyway, here are some links:
