Supported Versions
The following provides an overview of the supported versions of the Signum Server, as well as information about managing versions of the Signum Agents.
The general guidance is that Server Versions can be greater than Agent version. However, Agent versions cannot be greater than the Server Version unless the Major/Minor versions match. To reduce the number of Agent versions to manage, and if there are no changes to the Agents, matching versions of the Agents may not always be released with each update.
With each new Major or Minor release, Keyfactor supports the preceding release for a minimum of 12 months.
