I think everyone should upgrade to this release (and also the latest android app).
Thank you to the alpha testers who tested an early version of these change. This release adds fixes based on their findings.
(finally) Fixed a super nasty bug in the bluetooth library code (that I didn't even realize was there). Any packets sent from phone to device had a fair chance of corruption if they were larger than 20 bytes. With recent longer packets in the 0.7.x tree this manifested as "mysterious loss of bluetooth comms".
Also - an an upstream change in the esp32-arduino libs introduced a bug that could cause bluetooth state corruption which manifested as inability to pair and repeated requirements to repair.
Other fixes:
- Don't leak BLE handles (found while debugging the big bug)
- Fix out out packet errors if stress testing on big meshes
- Fix a hang that could occur (rarely) white trying to enter sleep
