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.
Three tiers are eventually released for every product:
- Early Adopter This tier is traditionally called RTM or “Release to Manufacturing.” It has passed internal tests and is ready to release into production environments. When a new version of Plesk is released – such as Plesk 12 – it starts in this tier.
- Release (Recommended) This tier is what is called GA or “General Availability.” After the Early Adopter release – where partners begin to deploy into production environments – our development and service teams work closely with partners to fix any issues found prior to releasing this Release Tier . Plesk ships any fixes/issues found in a series of Micro-Updates. After several (up to ten) of these Micro-Updates, the product version is declared as Release (Recommended).
After this tier is released, version-free Plesk for Linux Virtuozzo containers templates (i.e., templates with names like
pp-webmail ) are switched to the new release. This has the following consequences: * If Plesk is installed in a container using the version-free template
pp , running
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 #213953345 ). * 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* Late Adopter We recognize that some partners and customers are very cautious about upgrading, so we created a Late Adopter 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.
