Working on an existing project I had built with the arduino IDE 1.8.15 I was having some weird behaviors. I tracked this down to some variables stored in the platform.local.txt not being resolved in the arduino IDE 2.0.3. The sketch compiles for both IDE versions without issue but If I upload from 1.8.15, the properties are resolved from the platform.local.txt and they aren't when uploading from 2.0.3.
This is using the compiler.cpp.extra_flags option.
I couldn't find any new location where these files should reside that's different from the 1.8.15 version so I assume they would be reading the same file. Am I wrong with this assumption?
Currently resolving this file to the path:
c:\Users\<user>\AppData\Local\Arduino15\packages\arduino\hardware\<boardName>\<boardVersion>\
