This release (for alpha testers only for now) has a bunch of good bug fixes - especially for the new nrf52 boards.
- @audunf made packet routing smarter when the transmit queue is full. In that case, try to drop only low priority packets.
- @dmitryelj fixed support for boards that use the (less common) SH1106 display
- @flux242 fixed an invalid heap reference when using MQTT
- @claesg fixed battery sensing and sleep on nrf52
- Fix higher odds of dropping packets if a board was in light sleep (bug #801)
- Don't leak wifi passwords back to hosts (hosts can still set them, but can't read them) reported by @Vodkin
- Don't enter light-sleep state while talking to MQTT servers
- Show a max of four most recent nodes in the scrolling screen display
- Update to latest nrf52 arduino libs
- Fix #838 serial could hang when talking to nrf52 boards
