To better support testing of AJAX enabled websites, this release adds some more options to your toolbox.

A new method is added that will wait until some attribute has a certain value. This might be handy in situations where you need to wait until a value of an element gets updated.

// Wait until some textfield is enabled
textfield.WaitUntil("disable", false.ToSting, 10);
// Wait until some textfield is visible and enabled
textfield.WaitUntil(new Attribute("visibile", new BoolComparer(true)) && new Attribute("disabled", new BoolComparer(false)));

See the link to the release notes for more information.

I haven't looked into it in detail yet, so I cannot tell in which cases it might be useful or not. But thought it could be worth mentioning in case anybody else comes across this question.
