Firmware v1.20

• Garmin Varia radar support. Pair a Varia from the app or the Sensors
  screen and add a radar tile to any dashboard page: a column down the
  right side that shows cars coming up behind you and how far back they
  are, in feet or metres to match your units. You can make it full, three-
  quarter or half height, and pin it to the top or bottom of the page.
• Longer battery life. The device now sleeps between GPS updates and
  while the phone and sensors are connected but quiet, instead of staying
  fully awake the whole time it is on.
• Mesh messaging works outside the US. Choose your LoRa region, transmit
  power and frequency slot from the app's Mesh settings instead of
  rebuilding the firmware. Existing devices stay on the US band until you
  change it.
• Rides uploaded to Strava, intervals.icu and RideWithGPS now show
  OpenTrailPaper as the recording device, with the firmware version.
• If the device crashes, it saves a crash report to the SD card on the
  next boot, so a problem can be tracked down after the ride.

Built from 28d323a. Flash it from the app (Settings > Firmware), the project site, or drop firmware.bin on the SD card.
