Plesk Updates and Upgrades

Plesk is constantly evolving in terms of functionality, and new security enhancements are introduced with each update. To ensure that your Plesk software is up-to-date, we recommend that you switch on automatic updates.

There is also the option to upgrade Plesk to the latest versions. While updates include some minor improvements for Plesk, upgrades introduce more complex changes in product functionality.

The information about the current Plesk version and available updates and upgrades is always displayed in the System Overview group of the Home page.

Plesk Versioning

Starting from Plesk Onyx, each Plesk version consists of a name and version identifier. For example, in Plesk Onyx 17.0, Onyx is the name and 17.0 is the version identifier.

The shortened reference to Plesk version includes only the version name, for example, Plesk Onyx.

The full version identifier consists of a number of fields. For example, the identifier 17.0.12 Update 7 General release appears as follows.

Version number			Update	Release tier
Major	Major	Minor
17	0	12	7	General release

Information about how updates and upgrades affect these fields is provided next in this section.

Note

By default, Plesk updates and upgrades are downloaded from the official update server. Learn how to install updates and upgrades from other locations in the section Changing the Updates/Upgrades Source.
