What "fx" are available for Tabs

What fx can you use with JQuery UI Tabs? The only two I've been able
to find are opacity and height. Is there any way to do other
effects? I would like to "slide" or "blind" my content in; is this
possible?
It looks like it's possible on the old version: http://stilbuero.de/jquery/tabs/.
Did they take that functionality out of the new version?
