This is our sixth release candidate (RC6) for Betaflight 4.3.

Remember some things may need fixing and fine tuning, and there may still be bugs. Please use it with caution and report back any issues at https://github.com/betaflight/betaflight/issues. Thank you!

**Note: Failsafe code has been updated extensively. See: https://github.com/betaflight/betaflight/blob/master/docs/Failsafe.md

**Note: The Betaflight side of CRSF baud rate negotiation has been improved, but it will require new RX firmware to be released for best results. If you're experiencing issues, crsf_use_negotiated_baud should be kept OFF(default) until further notice.

IMPORTANT: Make sure you install and use the latest version of the Betaflight Configurator (10.8-RC6 or higher) from https://github.com/betaflight/betaflight-configurator/releases/tag/10.8.0-RC6 before updating your firmware.

To get the best out of the flight performance improvements, please read the Tuning Notes.
