The gds tools have been updated to branch 2.16.5.  The gds tools include diag, diaggui, chndump, foton, awggui, ezcaread, ezcawrite, ezcaswitch, ezcademod, ezcaservo, ezcastep, and some other utilites.  Here's a list of more significant changes:

GUI programs (diaggui, foton, awggui):

Expand channel field width in fields and menus that display channel names.

Ability to generate .png files for plots (bugzilla 420)

Update to allow more than 128 tp and awg responses from front ends

Release notes viewable from Help menu (if installed)

For foton:

Modify to report in much better detail errors that are encountered when reading a filter file.  Errors reading a file are indicated by changing the File... button to a red color.  When mouse clicking the red File... button, errors are displayed in a popup dialog box.  (see image 1)
Use caution if the File... button is red.  This indicates that saving the filter file will most likely result in some (defective) filters not being saved.

Change matlab merge batch mode to not display any ROOT graphics.  Batch mode foton returns 0 for successful operation or -1 (255) for failure.  Errors will be written to stdout if any are encountered.

Filters with output ramp set with 0 ramp time will be converted to immediate switching with a warning issued to the user.

Foton preserves filters that consist of only gain(1).

For ezcademod, expanded the number of channels it can read to 200,000.  This is inadequate, and is a stop-gap measure which will have a more permanent fix implemented.
