Great job on this release guys.
I also noticed when developing a plugin that it seems the memory management in IE6 is greatly improved. I accidentally was using 1.2.1 while trying to cut memory leaks in IE6, and when I switched to 1.2.6 the memory leaks on IE6 were gone. I'm not sure if it was some combination of my code and jQuery...am I imagining this, or is this also something that was worked on, or perhaps a by-product of other optimizations?
