The control room GDS software has been updated to gds-2.17.9-1 for Ubuntu 12.04 workstations.  This adds a leap second to the UTC/GPS conversion routines and fixes bugzilla 1064 (unit strings not read properly from NDS1), bugzilla 469 (improper channel list restriction in ezcademod).  The release also allows users to abort a DTT measurement when waiting to collect data that isn't available yet (part of bugzilla 474), and adds the ability to display units for channels in chndump.

Debian 8 workstations were already at gds-2.17.9-1. This is also compiled for SL6 if the hardware injection software needs it.
