The files in this directory helps to determine which UCS version is currently in maintenance. Every released UCS version has an unambiguous version number; it is composed of a figure (the major version), a full stop, a second figure (the minor version), a hyphen and a third figure (the patch level version). The version UCS 4.2-1 thus refers to the first patch level update for the second minor update for the major release UCS 4. For every UCS version since UCS 2.0-0 a YAML file has been added. The field "maintained" describes the current maintenance status. The following values are possible: * maintained: true That means this UCS version is currently in maintenance. Univention will provide updates for this release. * maintained: extended The extended security maintenance provides security updates for grave security vulnerability. If you want to use the extended maintenance, please inform us via our contact form: https://www.univention.com/contact/ * maintained: false For this UCS versions are no more updates provided. You should upgrade your UCS system as soon as possible. If you need more information, please contact us via email: feedback@univention.de Thanks, Univention Team
