Found a bug.
>>> import io Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: incompatible .mpy file
Edit: It helped to delete the io.mpy file under libs/micropython
Thank you for the update. Look like you've upgraded to 1.18, that's nice, that should speedup some dict loops.
Is there any documentation to the m5 package? Or do you have a changelog or something? Or can yoi upload the sources to github, so that we at can look for ourself for the functions?
