Arduino IDE: Switch between dev and stable release

[neophob]

I switched from beta toolchain (https://dl.espressif.com/dl/package_esp32_dev_index.json) to stable (https://dl.espressif.com/dl/package_esp32_index.json) - suddenly this issue popped up

Arduino: 1.8.8 (Mac OS X), Board: "Arduino Yún"

Board esp32 (platform esp32, package esp32) is unknown

Error compiling for board ESP32 Dev Module.

The problem was, I did not uninstall the beta toolchain. I fixed this issue when I removed the beta and the stable toolchain.

Not sure if this is an Arduino IDE issue or ESP toolchain issue.

@neophob this is definitely an Arduino IDE issue. Please file it over on the Arduino IDE issue tracker.
