Compatibility

This is a bugfix/patch release and is compatible with earlier 3.x versions.

Who should update from V3.6.2?

These are all backports from bugs found during 4.0.0-RC1 testing and seek to improve stability and performance for users experiencing:

• Rotorflight Configurator over wifi frequently disconnects before the tab can load
• Poor wifi / bluetooth connection stability caused by backpack being active when in these modes
• Telemetry stops updating when used with external telemetry sensors that generate malformed packets connected to the receiver
• SPI receivers constant connect/disconnect cycles due to VTX Admin on connect
• Note! elrs.lua from V4.0.0-RC2 (r16) can be used with 3.x as well. The version number has been removed and is compatible with ExpressLRS 2.x, 3.x, and 4.x
