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 10.6.0 (to be released in the coming days, installation instructions here). Please update your Betaflight configurator to version 10.6.0 (or newer) as soon as it is available, or use the CLI for now;
- if you are using the Blackbox Log Viewer, there will be an updated version 3.4.0 to go with Betaflight 4.1 (installation instructions here). Please update as soon as it becomes available;
- with the introduction of fully configurable VTX control (VTX tables), after flashing the firmware you now have to load a VTX tables appropriate for your VTX and for the country you are flying in before you can control your VTX through Betaflight. Support for loading VTX tables from files will be integrated in the upcoming Betaflight configurator 10.6.0, for now you have to use CLI to set up the VTX tables: https://github.com/betaflight/betaflight/wiki/VTX-Tables (#7251);
- some optimisations were made to the OSD fonts, and some characters were improved. In order to get a properly working OSD with Betaflight 4.1, the font loaded onto the OSD needs to be updated to the latest version (available in configurator 10.6.0 or newer) (#8390);
- as announced before the release of Betaflight 4.0, support for F3 based flight controllers has been removed from Betaflight 4.1.
