* Make Element#setStyle accept a string argument of CSS rules. Deprecate uncamelized style property names when setting styles using an object (for performance reasons). Closes #9059. [Tobie Langel]
Examples:
$('id').setStyle('font-size: 12px; float: left; opacity: 0.5');
$('id').setStyle({fontSize: '12px', cssFloat: 'left', opacity: 0.5});
!! BACKWARDS COMPATIBILITY CHANGE !!
If you have code that looks like this:
$('id').setStyle({'font-size': '12px'});
You need to replace it with either of the following:
$('id').setStyle({fontSize: '12px'});
$('id').setStyle('font-size: 12px;');
* Add Element#identify, which returns the element's ID if it exists, or sets and returns a unique, auto-generated ID (of the form "anonymous_element_" + auto-incremented digit) otherwise. Use this when you need to ensure an element has an ID. Closes #9012. [Jeff Watkins, sam, Tobie Langel]
* Make Element#readAttribute work for cloned elements in IE. Closes #8481. [chem, Tobie Langel]
