Updated: 2020-07-09

What's new

- When on a call, we show an LED that flashes as packets are received. We now also show this LED for each participant in a conference so you can tell if someone in your conference has fallen off the Earth.
- When you burn a message while offline, we now show a placeholder until the burn command can be sent.

- We now support more countries for Silent World dial assist.
