Corresponds with the release of a new product version.  •   Ry = minor release on the basis of a major release with a minor improvement in functionality.  •   z = fix release on the basis of a minor release. Generally only contains the correction of bugs.  •   n    -   = 0 in major releases, minor releases, and fix releases (generally available software editions).    -   = max. four-digit number for hotfixes for targeted use in case of a high-priority error (software editions on the basis of a fix release with limited availability).
