Overview of feature levels and metaschema versions

The feature level and metaschema version define the structure of the data stored in Rational ClearQuest schema repositories and user databases. New feature levels and metaschema versions typically add new columns to tables and new tables to databases in order to support new features of Rational ClearQuest.

Feature levels are associated with specific metaschema versions. The following table lists the supported feature levels and metaschema versions for every release of Rational ClearQuest.
