Release Summary

This first-ever release of Kubera includes services and enterprise support plans from MayaData to improve the operations of Kubernetes as a data layer. Kubera includes a free-forever individual tier, as well as paid tiers. Kubera introduces the OpenEBS Enterprise Edition, a platform validated and long-term support distribution of the open-source CNCF project OpenEBS and related components. The Enterprise Edition of OpenEBS brings automated life-cycle management of data layer components in addition to all of the features of OpenEBS 1.10.0 along with rigorous e2e testing, enterprise-grade platform validations, and hardening. Director introduces a large number of usability improvements and application-focused workflows including off cluster logging and alerting and enhanced back-ups and disaster recovery. Kubera includes all of these features under a single license.
