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|
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.
