Bug 591688 - Notify when decision task fails r=dustin,gps This uses the email provided by mozilla-taskcluster to find who to email about failed decision tasks. It also adds some validation of the try syntax that we've previously ignored. Any platforms or build types specified in try sytax that don't exist in the full task graph will throw an error.
