Because of new filters loaded by Rana last week, I wasn't sure there had been an update to the safe.snap file for the ITM and ETMs.  Since the IFO was down for Tuesday chaos, we therefore took new ones and committed them to svn.  While we were at it, we committed the safe.snaps for the 3 MC SUSes due to my addition of the SDF column to the files yesterday.
