User visible changes in the firmware version 3.3.7 since version 3.3.6.

                             Highlights.

1. Data link identifier in the GREIS [DL] message for /dev/ser/e port
   was changed from 'E' to 'V' to distinguish it from /dev/tcp/e port.

2. Fixed yet another possible cause of exception in RTK extrapolating
   algorithm.

3. Fixed possible severe tracking, measurements, and position
   computation problem that may occur because of redundant DSP
   interrupt that happens very rarely for yet unknown reason.

4. Fixed output frequency in SIGMA and DELTA receivers with TRE_G3T
   rev.6, and TRE_G3TAJT boards.
