are these changes backwards compatible?
I always get confused with the meaning of "backwards" vs "forward"
compatible, so let me state both. :)
Older rpkg will not work with files in the new format, they will just
raise exceptions trying to read them.
However, after being patched, rpkg still will be able to read files in
the old format. In fact, that's how files get converted to the new
