#72966 Can someone tell me how to use a different core version? I have a problem compiling against the current 2.4 or staging and can't figure out how to tell atom/pio (or the Arduino IDE for that matter) to use 2.3. Both the Arduino IDE and platformio allow for specifying a git url for the staging version https://github.com/platformio/platform- ... ture/stage but these are non-numbered to pretty much prevent want i want :roll:

#edit: It appears that other from switching manually to a lower version in the board manager and replacing 2.4 there is no way. I was hoping to have simultaneous installed versions like it works with stable/staging. Oh well.
