Each version of the Betaflight Configurator is configured to work with a certain subset of firmware for the flight controller. The Configurator's user interface (UI), options/settings/functions/features available via the UI, ranges, default settings/tuning, and the terminology/nomenclature (even for a feature/function that used to be the exact same function) changes between major releases/versions. There is no 100% backwards compatibility. As such, you MUST use the correct Configurator version for the firmware version on your drone. This simply a necessary evil when enjoying Betaflight's open source application and firmware.
