RateIt has been tested on 1.6 and 1.6.1, and works great.
The changes to jQuery don't affect RateIt.
The camelcasing only affect when getting all the data on an object:
var obj = $('#rateit').data() => here we now have obj.rateitValue
But our reading/write via $('#rateit').data('rateit-value') is still valid, and works as before.
