Plesk Lifecycle Policy

Plesk Lifecycle Policy

• A major version is defined as any change in the first digit(s) of the Plesk version number. For example, Plesk 12 and Plesk 11 are different major versions whereas Plesk 12.0 and 12.5 are not. From Plesk Onyx on, we will define new versions by a change in the version name as opposed to the version number.
• A preview version is defined as any Plesk version, which is only available through the non-default “testing” release tier in the Plesk Installer.
• Plesk will always provide software patches and accept technical support requests for the latest Plesk major version and its immediately preceding version.
• Plesk does not accept technical support requests for preview versions of Plesk. To report bugs and ask technical questions, go to the Plesk Community Forum. To submit feature requests, go to our Plesk UserVoice.
• Each major version will be fully supported for at least a period of four (4) years after release.
  • Extended Support: After this 4 year period, the product will no longer be available for new purchases and will continue to receive patches only for critical issues. This will last for a period of six (6) months.
  • End-of-Life: Once the Extended Support period is over, the product will stop receiving further development, and technical support requests will no longer be accepted.
• In order to ensure stable operation, it is required to be on the latest update/patch within a major released version of Plesk. Preview versions must not be used in production environments.
• Support for a particular instance is also dependent on using a currently supported operating system. This policy is described in the relevant section below.
• Even for unsupported instances, Plesk will continue to accept technical support requests that are related to updating to a supported version or environment. Exceptions are updates from and to preview versions, since the stability of such upgrades is not guaranteed.

Plesk version lifecycle

The table below describes when specific versions of Plesk will enter the Extended Support phase and when patches / support will no longer be available for them. If affected by one of the below dates, customers are encouraged to upgrade to a supported Plesk version:

* Starting from this date, Plesk begins accepting technical support requests for Plesk Obsidian Release Candidates (RC). Actual release date for Plesk Obsidian will be announced separately.
** The upgrade path for Small Business Panel customers involves a migration to Plesk 10, where these products were merged.

Currently supported OSes

The table below lists all operating systems on which you can install a supported version of Plesk, which also receive updates and support from the OS vendor. Consult Software Requirements section of the Plesk release notes for more information on OS compatibility of a particular Plesk release.

* We recommend using the latest supported version of an operating system when deploying a new server. This is because a server with such OS has the longest potential lifetime before its OS Vendor Termination Date.

Unsupported OSes

Plesk does not accept support requests and will not issue software patches for servers with OSes, that are not listed in the table above or if their Vendor Termination Date is past due.
