Please note

Starting with this release the build script for ESP-IDF framework uses CMake code model as the source of build configuration (old configuration methods using sdkconfig.h or build flags in platformio.ini are deprecated). For this reason a new project structure is required in order to compile ESP-IDF based projects. More information on project configuration can be found here.
