`backwards compatibility' is defined from a user's point of view. It
should be possible to install a new (minor) version, restart the daemon
and everything that used to work still should work. If an RRD-file needs
to be renamed or the config needs to be changed, that's not backwards
compatible.

Great :) The more bugs are found before the release the better ;)
