2.17. Versions and releases of PSM

As of June 2011, the following release policy applies to Balabit’s Privileged Session Management, Shell Control Box:

  • Long Term Supported or LTS releases (for example, PSM 4 LTS) are supported for 3 years after their original publication date and for 1 year after the next LTS release is published (whichever date is later). The second digit of the revisions of such releases is 0 (for example, PSM 4.0.1). Maintenance releases to LTS releases contain only bugfixes and security updates.

  • Feature releases (for example, PSM 4 F1) are supported for 6 months after their original publication date and for 2 months after a succeeding Feature or LTS release is published (whichever date is later). Feature releases contain enhancements and new features, presumably 1-3 new features per release. Only the last feature release is supported (for example, when a new feature release comes out, the last one becomes unsupported in 2 months).

For a full description of stable and feature releases, see Version Policy.

Warning

Downgrading from a feature release is not supported. If you upgrade from an LTS release (for example, 4.0) to a feature release (4.1), you have to keep upgrading with each new feature release until the next LTS version (in this case, 5.0) is published.
