This is a small fix to the last dev release, details:

        - remove test dep on YAML
        - additional speed tweaks for C3
        - allow scalarefs passed to order_by to go straight through to SQL
        - renamed insert_or_update to update_or_insert (with compat alias)
        - hidden lots of packages from the PAUSE Indexer
