Interim (Minor) Release: When it becomes necessary to correct faults detected on a released version, fixes are made to the base version. This modified version is installed as a minor release, which by definition does not contain any functional enhancements. Minor releases are planned by the Principal and made available periodically. According to general policy, underlying environmental software required for the run time is not changed in this release. A minor release completely supersedes previous minor and emergency releases and all customers are expected to upgrade their versions to the latest release.
