[WaF Bot]

Important

This is a release candidate. It is intended for testing, and some things still need fixing and fine tuning. Please use it with caution and report back any issues at https://github.com/betaflight/betaflight/issues. Thank you.

Important information when upgrading

• A number of changes and improvements in this release require changes to the Betaflight configurator. These changes have been added to Betaflight configurator 10.4.0 (to be released in the coming days, installation instructions here). Please update your Betaflight configurator to version 10.4.0 or better, or use the CLI for now;
• if you are using the Blackbox Log Viewer, there will be an updated version 3.2.0 to go with Betaflight 3.5 (installation instructions here). Please update as soon as it becomes available;
• a new 'Feed Forward PID' algorithm has been implemented, replacing setpoint weight (#6355). In addition to this, the dynamic notch filter (#6411) and anti-gravity (#6220) have been optimised for improved flight performance. For all of these changes, default values have been chosen that should result in good flight characteristics for most setups. It is recommended to start testing with default settings, incorporating tuned settings from previous versions if needed, where needed. For more in-depth instructions for tuning Betaflight 3.5, please consult these notes.

Major features:

• Added support for feed forward to the PID controller (#6355);
• Improved the performance of the dynamic notch filter (#6411).

Minor features:

• Improved the performance of anti-gravity (#6220);
• Added support for linking of modes (#6335);
• Added support for dynamic filter in dual gyro mode (#6428).
