Release Notes

This release contains all of the changes necessary to support version 4.1 of the Betaflight firmware. If you are using firmware 4.1, it is essential that you upgrade to this version, in order to get support for configuring the new features of 4.1. For a list of other new features that were added see 'New Features' below.

If your platform is not supported, but can run a recent version of Chrome, please follow these instructions to install the Betaflight Configurator from the Chrome web store.

We have tried to make this release as bug free as possible. If you still find a bug, please report it back to us by opening an issue here.

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 in the Slack messaging platform. Register here, and then come join us in Slack. 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.

Important information when upgrading

• Changes to the security model used in the latest versions of MacOS X 10.14 (Mojave) and 10.15 (Catalina) mean that the operating system will show an error message ('"Betaflight Configurator.app" is damaged and can’t be opened. You should move it to the Trash.') when trying to install the application. To work around this, run the following command in a terminal before installing: sudo spctl --master-disable. Then install Betaflight configurator, and after verifying that the installation has worked, run sudo spctl --master-enable.
