WebQA (+dev, probably) would like to be able to have Jenkins watch for SCM changes, a la SUMO: http://support.allizom.org/media/revision.txt (or do we want http://support.allizom.org/media/revision_info.txt?) hrm. If you could publish both of those for https://builder-addons-dev.allizom.org, that'd be great; thanks!
builder-addons-dev.allizom.org is using freddo for update. I have submitted the following pull request to add revision.txt during updates. https://github.com/mozilla/FlightDeck/pull/70
Verified FIXED on https://builder-addons-dev.allizom.org/media/revision.txt; thanks, Jason/Piotr!
