Plesk Lifecycle Policy

Full text changes — 20210117_rev01 to 20210302_rev01

1Plesk continues to evolve from a basic and feature-based control panel to a powerful management platform proven on Server, Sites, Apps, Hosting & Cloud Businesses. Rapidly changing technologies require an update to the Plesk Lifecycle and End-of-Life (EOL) policy. This new approach supports Plesk users in staying ahead of the game, mitigating security risks, by making it easier for Plesk partners and customers to always be on the latest software version.

11With the launch of Obsidian, Plesk is ending the era of upgrades and introduces a monthly release cycle. Switching to monthly updates is imperative to always deliver a secure and stable version of Plesk with new features and improvements that Partners and Customers expect to get from an intelligent software solution.
12In the past, Plesk used to launch one major version per year and users were required to upgrade the Plesk server (e.g. 12.x > 17.x). With Plesk Obsidian, users are strongly recommended to allow automatic updates through [Plesk Server settings](https://support.plesk.com/hc/en-us/articles/360000283234-How-to-disable-auto-updates-in-Plesk-) so they will automatically be on the latest version including hotfixes, security patches, micro updates, and more. The [dedicated blog article](https://www.plesk.com/blog/partners/plesk-obsidian-the-beginning-of-a-short-releases-era/) offers additional details about monthly updates and the changed approach.

14**IMPORTANT NOTE:**
10EXTENDED SUPPORT\*
1511
161. An up-to-date and supported Plesk installation with all the latest available updates installed is a prerequisite for technical support from Plesk.
172. Security patches, security updates and/or hotfixes are **NOT shipped when automatic updates are disabled.**
12 |
1813
19_**Disclaimer: In case automatic updates are disabled on a particular Plesk server, the owner of the server acknowledges and agrees to take full responsibility for any resulting potential security risks and/or hacker attacks to his server. Plesk specifically disclaims any liability or responsibility in these cases of disabled security settings.**_
14END OF LIFE\*\*
2015
21Plesk highly recommends to enable automatic updates if the user wants the Plesk server(s) to be stable and secure and have access to support.

23- A **major version** is defined as a change of the first digit(s) of any **Plesk version** number. For example, Plesk Onyx (17.x) and Plesk Obsidian (18.x) are different major versions. Starting with Plesk Obsidian, version 18 will remain a major version that will be supported.
24- For Plesk Obsidian (18.x), software patches are provided and support requests are accepted for the latest available update of this major version as well as the preceding update (see example). For all other versions, the Plesk version life cycle table below applies.
20Plesk Obsidian
2521
26_**Example:**_ Plesk 18.0.15 is installed by the user as fresh instance. After one month, if the user decides to install a fresh instance of Plesk, its version will be 18.0.16, meaning that the user will not even find the older version 18.0.15. At the same time, version 18.0.15 will continue to be supported until version 18.0.17 is released. In this example, version 18.0.17 is the latest update, while version 18.0.16 is the preceding update.

82\* Plesk recommends using the latest supported version of an operating system when deploying a new server because a server with a current OS has the longest potential lifetime before its OS Vendor Termination Date.

86Plesk 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.

90Plesk does not accept technical support requests for **preview versions of Plesk**. Bug reports and technical questions for preview versions should be submitted through the [Plesk Community Forum](https://talk.plesk.com/). Feature requests should be submitted through the [Plesk User Voice](https://plesk.uservoice.com/).
194 |
91195
92For older unsupported versions of Plesk servers, Plesk strives to assist and accepts technical support requests, but only the ones related to upgrading to a supported version or environment. Exceptions are updates from and to preview versions, since the stability of such upgrades is not guaranteed.
196December 31, 2021
93197
94If a user's Plesk version is approaching its End of Life phase or the OS is approaching its Vendor Termination Date, Plesk recommends migrating to the latest Plesk version and a supported operating system. If a user needs migration instructions, advice, or if the user would prefer to let Plesk professionals handle the migration, the user should [contact the Plesk Professional Services](https://www.plesk.com/professional-services) team.
