UCS maintenance cycle rules

Logo Univention Corporate Server (UCS)

The following basic rules for the UCS maintenance cycle apply. UCS product versions are divided into major and minor releases.

A major version focuses on fundamental extensions and interfaces may be changed. Example for a major version is UCS 3.

  • UCS major versions are published ca. every 3-4 years.
  • UCS major versions have a maintenance cycle of at least 5 years.

During its maintenance cycle a major version receives several minor updates through minor versions that are comparable to the Service Packs of Microsoft Windows. Such a minor version focuses on the extension of the product and on bug fixes. Interfaces will only be extended in a compatible way or cleared up upon issues. UCS minor versions allow a simple and automatic update. Example for a minor version is UCS 3.1.

  • UCS minor versions are published ca. every 12 months.
  • UCS minor versions have a maintenance cycle of at least 1 year.
  • The maintenance cycle of a UCS minor version ends 6 months after the release of the following version.

Minor enhancements and fixes for small issues are continually provided by Errata Updates and collected in Patchlevel releases (e.g. UCS 3.1-1). They are public available through the Online-Update in Univention Corporate Server.

  • The maintenance cycle of a patchlevel release ends 6 weeks after the release of the following patchlevel.
