This update broke all my various production codes!
I can compile and upload but they don’t run like usual (rotary not working anymore / I2C display not working …)
I have a second machine still on 3.2.0 and it works fine when I compile and upload the same code (shared via Dropbox)
I reverted to 3.2.0 using pio platform install atmelsam@3.2.0 and my codes run again

maybe you are making too much modification in one go ?
could you split the update like
3.2.1 : Update Adafruit Core to 1.2.3
3 2.2 : Update Arduino Core to 1.6.19

etc …
to let us find where to look ?

here is my platformio.ini

[env:adafruit_feather_m0]
platform = atmelsam
board = adafruit_feather_m0
framework = arduino
lib_ignore = SDU
lib_deps =
 868
 1192

Thanks in advance

Please sorry for the issue. Could you file an issue in GitHub - platformio/platform-atmelsam: Atmel SAM: development platform for PlatformIO ?

You can use a different dev/platform per project. Just use platform = atmelsam@3.2.0

How do you get to track the changes made by Arduino or Adafruit ?

Arduino Sam core 1.6.19 doesn’t say what they changed in their Changelog
Same with Adafruit : they don’t even maintain their changelog !
So we have to check all their commits to find what is wrong ??

Ok I think I nailed it: see the GitHub issue Version 3.4.0 : my code is not working anymore · Issue #38 · platformio/platform-atmelsam · GitHub
