User visible changes in the firmware version 3.4.1 since version 3.4.0.

                             Highlights.

1. H24 (3G) modem will now switch to 2G network when 3G network is
   unavailable.

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

3. Support for TR_G3TH rev.6, including restored feature (abandoned
   in rev.5) of temperature measurements in RF part.

4. Support for TRE_G3TAJT rev.3, including new feature of
   temperature measurements in RF part.

5. Support for TR_G3H rev.6, rev.7.
   Support for TR_VS_LS rev.2.
   Support for DUO_G3D rev.4.
   Support for QUA_G3D rev.6.
   Support for TRE_G3TH rev.8, including E5B band.
   Support for TRIUMPH1 RF rev.9, including E5B band.

6. TRE_G3TAJT: make Ethernet chip enter low power mode when cable is
   disconnected.

7. Tracking of GALILEO SVs #11 and #12 is turned on by default.

8. Fixed problem that prevented simultaneous GIOVE and GALILEO
   tracking (introduced in 3.4.0).

9. Fixed handling of leased options so that they do not stuck in
   disabled state due to improper date in the future.

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

11. Fixed problem missing RTS RS232 signal for configurable ports
    (RS232/RS422).

12. DUO_G3D: fixed bug that disabled RS ports C&D when turning antenna
    power.

13. Fixed problem: the value of '/par/cmd/create/prefix' parameter is
    not preserved over re-boots.

14. Beidou/Compass svs numbering changed according to published ICD.
    sv=1 - compass-G1 satellite (GEO);
    sv=3 - compass-G3 satellite (GEO);
    sv=4 - compass-G4 satellite (GEO);
    sv=5 - compass-G5 satellite (GEO);
    sv=6 - compass-IGSO1 satellite;
    sv=7 - compass-IGSO2 satellite;
    sv=8 - compass-IGSO3 satellite;
    sv=9 - compass-IGSO4 satellite;
    sv=10 -compass-IGSO5 satellite;
    sv=30 -compass-M1 satellite (MEO).
    Number of available svs is 30 now.

15. Support for remembering of power state TRE_G2T rev.7 and
    TRE_G3T rev.8 boards implemented.

16. 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.

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

18. TR_VS: fill rotation matrix from compass/clinometer data,
    independently from position computation.

19. /par/dev/udp/X/omargin: fix resetting to default value on reboot
    (value was not stored in NVRAM).

20. Fix receiver reboots because of overload when Ethernet is flood
    with broadcast UDP packets.

21. New NGS antenna database has been imported.

22. Fixed handling of antennas at the end of antenna list (with indexes
    higher than 255).

23. DELTA: fixed loading of firmware into the power board.
