I've updated the Butterfly traffic display firmware;
fixed a number of bugs and it now works properly with
newer FLARM protocol. Lots of Butterfly displays were
purchased with the initial batch of USA PowerFLARM cores.

Special thanks to Kirk, Dan, Uli, and Cliff for the help
testing numerous releases, Patrick for loaning me a test unit,
and to the Butterfly guys for sending me the source code to update!

Update as follows:
- format a USB stick
- in your browser, left-click on link below
- save page as bfd_4_0.bfw onto USB stick (no TXT suffix or other bollix)
- with power off, plug stick into flarm core
- while depressing butterfly button, power-on flarm/butterfly
- Butterfly will initially show "Waiting"...
- Butterfly should start loading within 15-30 seconds
- Wait a couple minutes and you should see Butterfly start with new firmware

Enjoy,
Best Regards, Dave
