## Where each device has got to

A set takes a change by fetching it, which it does within a few seconds of being told — so anything still behind is switched off, mid-film, or cannot reach the gateway.

## Change history

Restoring puts an earlier version back as a new change, so the televisions notice it and the version it replaced stays here to return to.
