The upgrade from 15.3 to 15.4 upgraded my existing leafnode 1.11.11-bp153.1.18
to leafnode 2.0.0+git.1527241185.66da754-bp154.1.26.

The two versions are not compatible, migration is impossible and the new
version simply will never work, without intensive adjustment by the operator.

The configuration file is totally different, and the message store is also
different (it has to be downloaded again). This operation resets the reading
marks in the clients.

It is havoc.

Not even a warning about this in the release notes.
