Release Cadence and Support Lifecycle


In correlation with the end of life (EOL) date for MKE 3.5.x, Mirantis stopped maintaining this documentation version as of 2023-NOV-22. The latest MKE product documentation is available here.

With the intent of improving the customer experience, Mirantis strives to offer maintenance releases for the Mirantis Kubernetes Engine (MKE) software every six to eight weeks. Primarily, these maintenance releases will aim to resolve known issues and issues reported by customers, quash CVEs, and reduce technical debt. The version of each MKE maintenance release is reflected in the third digit position of the version number (as an example, for MKE 3.5 the most current maintenance release is MKE 3.5.12).

In parallel with our maintenance MKE release work, each year Mirantis will develop and release a new major version of MKE, the Mirantis support lifespan of which will adhere to our legacy two year standard.

Technology Preview features

A Technology Preview feature provides early access to upcoming product innovations, allowing customers to experiment with the functionality and provide feedback.

Technology Preview features may be privately or publicly available and neither are intended for production use. While Mirantis will provide assistance with such features through official channels, normal Service Level Agreements do not apply.

As Mirantis considers making future iterations of Technology Preview features generally available, we will do our best to resolve any issues that customers experience when using these features.

During the development of a Technology Preview feature, additional components may become available to the public for evaluation. Mirantis cannot guarantee the stability of such features. As a result, if you are using Technology Preview features, you may not be able to seamlessly upgrade to subsequent product releases.

Mirantis makes no guarantees that Technology Preview features will graduate to generally available features.
