Plesk Plesk Lifecycle Policy changes — 20190401_rev01

1

Plesk is committed to providing high-quality, cost-effective solutions to our customers. Rapidly changing technologies influence the level, timing and character of demand for particular product versions and components. All of this drives the need to introduce new products and services as well as to end support for older software versions.

To assist our customers in this regard, we provide a clear lifecycle and end-of-life (EOL) policy to assist in planning decisions around using and upgrading both Plesk and the environment in which it is running.

- 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 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.

12

- A **preview version** is defined as any Plesk version, which is only available through the non-default ["testing" release tier](https://support.plesk.com/hc/en-us/articles/213373849-Plesk-Release-Tiers) in the Plesk Installer.

13

- Plesk will always provide software patches and accept technical support requests for the latest Plesk major version and its immediately preceding version.

15

- Each major version will be fully supported for at least a period of four (4) years after release.

16

- 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.

17

- End-of-Life: Once the Extended Support period is over, the product will cease to receive further development and technical support requests will no longer be accepted.

18

- In order to ensure stable operation, it is required to be on the latest update / patch within a major version.

14

- Plesk does not accept technical support requests for preview versions of Plesk. Bug reports and technical questions must be submitted through the [Plesk Community Forum](https://talk.plesk.com/). Feature requests must be submitted through our [Plesk UserVoice](https://plesk.uservoice.com/).

- 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.

19

- Support for a particular instance is also dependent on using a currently supported operating system. This policy is described in the relevant section below.
