The GDS software in the control room has been updated to gds-2.17.9-2 (branch) to correct a bug in foton and add an enhancement to the NDS2 interface to diaggui.  This affects Debian 8, Ubuntu 12.04, and Ubuntu 14.04 workstations.

For control room use, the following bugs were fixed:

Bugzilla 1072 - Add GDS channel names to the list of channels displayed using the NDS2 interface.  This allows ${IFO}:GDS-CALIB_STRAIN channels to be analyzed using diaggui.

Bugzilla 1075 - Changed format of the gain coefficient in filter files as written by foton to include more decimal places.  Some filters with very large gains were being flagged as having a mismatch between design and coefficients because not enough decimal places were used (with very large gain values) and the filter could not be reconstructed accurately using the coefficients from the filter file.  Note that the affected filter files will still report this condition with the new version of foton until foton is used to rewrite the filter file with the new format.
