Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!
Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.
Container Cloud releases¶
This section outlines the release notes for the Mirantis Container Cloud GA releases until Container Cloud 2.29.x. Since 2.30.0, Container Cloud became part of Mirantis OpenStack for Kubernetes (MOSK) and was renamed to MOSK management.
For the latest supported MOSK management (formerly Container Cloud) release, see the MOSK latest version correlation table.
Within the scope of the Container Cloud GA release, major releases were published with new features, improvements, and critical issues resolutions to enhance the Container Cloud GA version. Between major releases, patch releases that incorporate fixes for CVEs of high and critical severity were delivered. For details, see Container Cloud releases, Cluster releases, and Patch releases.
When a new Container Cloud release was available, a management cluster automatically upgraded to a newer consecutive release unless this cluster contained managed clusters with a Cluster release unsupported by the newer Container Cloud release. For more details about the Container Cloud release mechanism, see Reference Architecture: Release Controller.
