Yesterday with the boot of h1oaf, the matrix elements for Modes 27 & 28 began using TRY QPD CHAN2 rather than OMC DCPD CHAN2.  This is because the safe.snap was set for TRY QPD CHAN2.  This file had not been updated since 18 October, even though these elements were set on 20 October.  Based on the trends, looked like this was spotted again last Tuesday when the OAF was restarted, again, the SDF was not updated.

There are currently ~40 diffs on the SDF and no NOT_MONITORED channels.  Maybe some of the gains and filters of these channels should be not monitored so things like signal source path changes will stand out.
