User visible changes in the firmware version 4.1.04 since version 4.1.03.

                             Highlights.

1. Power management: change battery poweroff level threshold at 6.4[V]

2. UHF: Support LMR404RF (ID:761) radio in Triumph3

3. BEACON: support beacon scanning mode

4. TRE-3S, TRE-3L: enabled attitude support

5. Fixed "print,/par/net/wlan/ap/passphrase"

6. Sessions: clear /par/sess/stat/time/next when /par/sess/mode is off

7. TRE_3S, TRE_3L: fixed RS422 mode of serial ports as well as RTS/CTS
   handling on serial C and D.

8. OMEGA: fix firmware downgrade from verion 4.2 to version 4.1

9. TLS/SSL: fix built-in NetBrowser support

10. HTTP: redirect to the master host using https:// address when
    TLS/SSL is in use, rather than using http://. This improves
    security.

11. First generation receivers (based on T1 DSP chip): fixed
    satellites fast lock/acquisition when vmax=10000 and Galileo E1
    and/or L1C/B1C signals are enabled

12. USB: do not fail on broken hardware, so that receiver has a chance
    to continue to work.

13. OMEGA: fix rare failure to start firmware correctly

14. New antenna database has been imported <NGS-21/11/18=854>.
