This Roadmap defines OpenEBS features and capabilities that are in current development and may be included in upcoming releases.
Community and contributor involvement is vital for successfully implementing all desired items for each release. We hope that the items listed below will inspire further engagement from the community to keep OpenEBS progressing and shipping exciting and valuable features.
OpenEBS follows a lean project management approach by splitting the development items into current, near term and future categories.
This table contains a list of both near-term and long-term backlog items. Near-term features are currently getting the most active focus and attention within the project. These are prioritized and planned to be completed within the next major release where higher priority is given to usability, stability, resilience, data integrity issues reported by the community. The long-term features require significant design and development efforts, and will be scoped in the future.
OpenEBS follows a release cadence with a new minor release every 3-4 months.
Note: The planned release timelines, version numbers and feature priorities are subject to change as the project maintainers/leadership/community continuously update and adjust in response to K8s industry movements, trends and our community influence.
Note 2: The table contains the high-level backlog items. For a comprehensive list of features and issues, please refer to https://github.com/openebs/openebs/releases.
