The official policy is that file format changes must be backwards
compatible not forwards compatible. In other words, the user will have
to download the version KiCad where the change was made.
If you make any changes to any of the file formats, you must increment
the file format rev number. This will cause the appropriate exception
to be raised which will warn the user the file version is newer than the
file version supported by the version of KiCad they are using.
Since this is all very new and has not been planned for the stable 5
release, I would most likely merge this into the master branch after the
stable 5 branch is created.
