Very, very little in comparision to Enceladus, but there may be some small-scale current activity. Article here.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The problem of course with imaging any venting from Dione is whether 6 grams of water vapor is enough to have much, or any for that matter, entrained ice grains, which we could observe with ISS, for example. The obvious candidate location for venting are the bright fracture walls in the wispy terrain (maybe sapping slowly releasing water vapor...)
