Updating Clusters#
Version: 30 Jan 2023
The OpenShift cluster and its components are constantly evolving, with functional and security issues being detected and fixed during operation. New features emerge regularly.
Types of Updates#
The following update types are available:
-
Major-release is a planned update of cluster components that involves making backwards-incompatible API changes. Releases result in incrementing the major version (
X) component in the semantic version number (X.Y.Z). -
Minor-release is a planned update of cluster components that involves a feature extension or change. Releases result in incrementing the minor version (
Y) component in the semantic version number (X.Y.Z). -
Patch-release is an unplanned update of cluster components to fix errors or other functional issues that have already led or may lead to instability of the cluster. Patch-releases result in incrementing the patch version (
Z) component in the semantic version number (X.Y.Z).
