I should have informed you about compatibility issues.  Sorry for
that.

We've changed a hash function for better balancing, so there is no
compatibility between 0.8.0 and 0.7.x.  I have a plan to provide a way
to upgrade from 0.7.x, but, probably, it will come after the 0.8.0
release.

If you already have a cluster with sheepdog 0.7.x, please wait for
upgrading it for a while.

Thanks,
