Releases
Convox follows semantic versioning (major.minor.patch). Minor versions introduce new features, Kubernetes upgrades, and dependency updates. Patch versions contain bug fixes, small improvements, and backported features.
New releases are published on the Convox GitHub Releases page. This section provides a structured, browsable history of all releases from 3.15.0 onward (3.20.0+ are the currently supported versions).
Kubernetes Version Compatibility
Each Convox minor version targets a specific Kubernetes version. Upgrading your rack to a new minor version will upgrade the underlying Kubernetes cluster.
