This update includes a lot of changes, so don’t hesitate to contact us if faced any issue 
Why not latest ESP32 version v3.0.2?
Version v3.x.x uses newer Espressif libraries, which has a lot of braking changes. This results in slightly increased code size, changed API and incompatibility with some Arduino libraries.
Our used ESP32 chip variant doesn’t benefit much from these updates, so it is wise to stick with stable release and wait until new version is fully established.
