Conduit 0.9.0 includes [a database migration][conduit-db-16-migration] that
modifies data that Grapevine doesn't read. Grapevine does not currently
recognize the new db version, and will fail to start against a conduit 0.9.0
database. Grapevine can start and run without issues if the version recorded in
the db is rolled back from 16 to 13. It is possible to do this by editing the
db manually, or by modifying grapevine to change the version. [This
patch][conduit-db-16-patch] is an example of the latter approach.

Conduit 0.8.0 added [a new database table][alias_userid-commit] to track which
users created each room alias. Grapevine does not write to this table, so it is
not possible to delete aliases created in grapevine through the normal
client-server API after migrating to conduit 0.8.0. It is possible to delete
aliases with the `remove-alias` admin command. Not that this issue also applies
to migrations from conduit 0.7.0 to conduit 0.8.0.
