sliderstop event.

I was trying to get the change event on a slider to work and it would not file. I googled sliders and found sliderstop on stackoverflow and it works fine. I am using 1.4.5 and in the docs for that version, sliderstop does not exist. I did find sliderstop in 1.2 docs. Has that event been discontinued? If so, is there another event that I should be using?

Thanks.
