This class is designed to support the Class::DBI connection-as-classdata style
for DBIx::Class. You are *strongly* recommended to use a DBIx::Class::Schema
-instead; DBIx::Class::DB will continue to be supported but new development
-will be focused on Schema-based DBIx::Class setups.
+instead; DBIx::Class::DB will not undergo new development and will be moved
+to being a CDBICompat-only component before 1.0.
