The table displays the packages currently installed in the schema repository. If you are adding a package to a checked out and open schema, the list displays the newest revision of each package which is compatible with the data code page of the schema repository. For schema repositories with data code pages 932 or 60932 (Japanese), or 936 (Simplified Chinese), the latest translated revision is displayed. For other schema repositories, the latest English version is displayed. Packages with an Upgrade version replace the add-in functionality found in previous versions of Rational® ClearQuest®. For example, if you used the Rational ClearCase® add-in with a schema, you would want to update that schema with the Rational ClearCase Upgrade package.
