Release Notes

This section describes the latest changes, enhancements, known issues, fixes, and deprecations for Mirantis Kubernetes Engine (MKE) for versions 3.5.x.

Considerations

  • Upgrading from one MKE minor version to another minor version can result in the downgrading of MKE middleware components. For more information, refer to the middleware versioning tables in the release notes of both the source and target MKE versions.

  • CentOS 8 entered EOL status as of 31-December-2021. For this reason, Mirantis no longer supports CentOS 8 for all versions of MKE. We encourage customers who are using CentOS 8 to migrate onto any one of the supported operating systems, as further bug fixes will not be forthcoming.
