Release cadence and support cycle¶
Mirantis aims to release Mirantis OpenStack for Kubernetes (MOSK) software regularly and often.
MOSK software includes OpenStack, Tungsten Fabric, life-cycle management tooling, other supporting software, and dependencies. Every release contains new functionality as well as bug and security fixes.
Mirantis’s goal is to ensure that such updates are easy to install in zero-touch and zero-downtime fashion. Mirantis encourages customers to install updates shortly after they become available.
Cloud API components versions and support cycle¶
Mirantis provides Long Term Support (LTS) for specific versions of cloud user-facing components that include OpenStack and Tungsten Fabric. LTS includes scheduled updates with new functionality, bug and security fixes.
Mirantis intends to introduce new LTS combinations once a year. Duration of a supported combination of OpenStack and Tungsten Fabric versions LTS is 2 years.
Versions of underlying Kubernetes, Ceph, StackLight, and other supporting software and dependencies may change at Mirantis discretion.
The table below illustrates the LTS support cycle for OpenStack with Tungsten Fabric versions in MOSK. The upstream versions not mentioned in the table are not supported in the product as well as the upgrade paths from or to such versions.
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.
