  v1.3.4 — A safer shutdown when the receiver is pulled out
  FIXES
  • Pulling the receiver out of the phone while it is decoding could
  close the app on some devices.
  • If reception cannot be started at all, the app now says so and
  returns to the stopped state instead of waiting indefinitely.

  v1.3.3
  FIXES
  • Unplugging the receiver while it is decoding no longer stops the app.
  • Automatic gain keeps its sensitivity when you change frequency.
  Until now, switching to another band cost about 10 dB, so the weaker
  sensors stopped coming through after a change.
  • Receivers with an FC0013 tuner now switch bands correctly.

  v1.3.2 — Choose your own light or dark theme
  
  NEW
  • Settings → Sensor Display now has a Theme option: Follow system,
  Light, or Dark. Pick Dark to keep the app dark even when your phone
  is set to light mode (or the other way round). The change applies
  right away and is remembered the next time you open the app.
  "Follow system" stays the default.

  now always reflects the live filter state.
