This is our seventh release candidate (RC7) for Betaflight 4.3.

This release candidate is likely to be the final release candidate before we do a final, and move to start working on 4.4. We anticipate that the final release will be in approximately 7 days (if no major issues are discovered).

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-RC7 or higher) from https://github.com/betaflight/betaflight-configurator/releases/tag/10.8.0-RC7 before updating your firmware.

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

If you want to talk about Betaflight, ask configuration questions, or just hang out with fellow pilots, you can do this in our Facebook group.

Betaflight also has a presence on the Discord messaging platform. Come and join us. Most developers hang out there, so this is a great place to talk about the things you are tinkering with in Betaflight, or get help with really complicated configuration problems.
