Plesk continues to support “Release Tiers” – a systematic way for customers and hosts to select the visibility of Plesk upgrades, along with automatic settings for upgrades.
Release Tiers can be selected on the Tools & Settings > Update and Upgrade Settings screen in the Plesk interface.
Every Plesk version comes in a variety of tiers that become available over time, one after another. Each tier comes with its own advantages and peculiarities, detailed below. Read the descriptions to understand which tier works best for you.
. Before the official release of the upcoming Plesk version, public previews of this version start becoming available. The previews are usually released on a monthly basis and include the new features developed up to the moment of the latest preview release.
Choose this tier if you want to test the new features of the upcoming Plesk release. Be prepared to encounter bugs. Some features may be incomplete, missing, or they may not operate properly. We do not recommend using this tier in production.
Early adopter release
. The RTM (Release to manufacturing) date for the latest Plesk release coincides with the early adopter release becoming public. This tier is fully functional, contains all features included in the latest Plesk release, and has been extensively tested and certified by the Plesk QA team. However, hiccups are possible.
Choose this tier if you are willing to sacrifice some stability to get the newest Plesk features and be among the first to offer these features to your customers. We do not recommend upgrading production servers to this tier without testing the upgrade in staging first.
(recommended). The availability of this tier is linked to the GA (General Availability) date for the latest Plesk release. This tier is fully functional, contains all features included in the latest Plesk release, and comes with a number of updates released after RTM that include bugfixes, as well as stability improvements and security patches.
Choose this tier if you favor a balanced approach. You will get the newest features sooner than the late adopters, and will enjoy greater stability than the early adopters.
Late adopter release
. By the time this tier becomes available, the latest Plesk version has been out long enough to have most of its nagging issues discovered and fixed. You can be certain that the Plesk version you are about to install has already been used in production environments for some time, and there are no major issues that could compromise the stability of your Plesk servers..
Choose this tier if you prefer stability over new features, and you are willing to delay going to market with the latest Plesk features and improvements to get a rock-solid stable performance.
After this tier is released, version-free Plesk for Linux Virtuozzo containers templates (i.e., templates with names like
) are switched to the new release. This has the following consequences: * If Plesk is installed in a container using the version-free template
vzpkg update <CTID>
on the container will cause Plesk to upgrade to the new version. * Installing a version-free template on a container with an existing installation of Plesk will cause Plesk to upgrade (see KB article
). * All new containers to which a version-free template is installed will have the latest version of Plesk installed. * Support for VZ templates for Windows was dropped in Plesk Onyx due to extremely low demand in Plesk 12.5*
We recognize that some partners and customers are very cautious about upgrading, so we created a
release tier that indicates a level of stability that a very cautious host or customer might prefer. Our experience with the Plesk 10.4 and Plesk 11.0 releases has been that this stage is reached in 6 to 8 weeks from Early Adopter/RTM; however, the lag may vary from release to release.
