    * fix [de]serialization bug of vocabulary constraints in case

      should be inlined on the entity to which the constraint apply)



2010-06-21  --  0.29.1
    * not use a hardcoded datatype for string colums with a max length (closes
      #35380). When a dbhelper provides a SizeConstrainedString entry in the
      TYPE_MAPPING dictionary, use it, otherwise default to varchar(%s).

    * avoid spurious warnings in functions defined in schema modules and called
      after that module loading by another schema module (stop removing stuff from

    * permissions are now handled by relation definition, no more
      by the relation type

    * introduce (finally) RelationDefinition objects into schema
      instead of simple rproperties on the relation type. Update
      the api consequently.
