Today we are releasing Ember.js 1.8.1, a patch-level release of Ember that
fixes several minor regressions introduced in the 1.8 release.
Throw exception when attributeBindings includes class
Prior to 1.8, it was possible to make class part of attributeBindings and have
those values merged with classNameBindings. For example, with the following template
and code "from-template" and "from-class" would be merged into the DOM node's class
list.
