Slider documentation does not seem to correspond with code

Slider documentation does not seem to correspond with code


1) The code seems to pay attention to an option called "values". That
option is not mentioned in the API documentation.
2) The documentation describes an option called "handles", but it
doesn't look to me as if the code pays attention to it.
3) The documentation says that event handlers will be passed an object
that includes a reference to which handle has changed, but that does
not appear to be the case - the code to me indicates that the callback
is only given the value of the changed handle.
Am I looking at the wrong documentation?
