No, we don't document internal API changes like this. You can
usually find out how to change the code by looking through the
git history or git blame information for where the change to the
API was made to see how other boards were changed. And some
fixes are simple -- for instance your issue with serial_hd()
not being declared is likely just a missing #include line.
