> At a minimum this ticket covers packaging up example MySQL migration scripts (cumulative
across all schema changes from 0.5 to 0.6) and explaining what to do with them in the release
notes.
> This is also probably a good point at which to decide and clearly state which Metastore
DBs we officially support in production, e.g. do we need to provide migration scripts for
Derby?
