Release compatibility
What each supported Tetrate Agent Router release requires and ships, one row per release. The table is rendered from the release contract that tare install enforces and from the release notes, at the same moment the notes are rendered, so it cannot drift from either.
How to read the columns:
- Kubernetes is the cluster range the release accepts. The range is fixed per release and enforced when the data plane is installed or upgraded: a cluster outside it is refused with an error naming the range. Managed Kubernetes cannot be downgraded in place, so the range is worth checking before a cluster is built, not after.
- Envoy Gateway is the version series the data plane ships and accepts for the release.
- Minimum data plane is the lowest data plane release on which every feature in that release is available. A data plane below it keeps working; the features that need a newer one stay off until the data plane is upgraded, and each such feature names its version in the release notes.
- The
tareCLI version matches the release tag.
