Tekton Chains Releases

Release Frequency

Tekton Chains follows the Tekton community [release policy][release-policy] as follows:

• Versions are numbered according to semantic versioning: vX.Y.Z
• At a minimum four LTS release are produced. Additional releases are produced based on availability of new features to be released
• Four releases a year are chosen for long term support (LTS). All remaining releases are supported for approximately 1 month.
  • The first Tekton Chains LTS release will be v0.13.0 in October 2022

Tekton Chains produces nightly builds, publicly available on ghcr.io/tektoncd/chains/controller-92006fd957c0afd31de6a40b3e33b39f.

Transition Process

Before release v0.13 Tekton Chains has worked on the basis of an undocumented support period, providing patch releases when needed. While transitioning to the new support model, v0.11 and v0.12 will be supported for four months from the initial publishing date.

Release Process

Tekton Chains releases are made of YAML manifests and container images. Manifests are published to cloud object-storage as well as [GitHub][tekton-chains-releases]. Container images are signed by [Sigstore][sigstore] via [Tekton Chains][tekton-chains]; signatures can be verified through the [public key][chains-public-key] hosted by the Tekton Chains project.

Further documentation available:

• The Tekton Chains [release process][tekton-releases-docs]
• [Installing Tekton][tekton-installation]
• Standard for [release notes][release-notes-standards]

Backwards Incompatible Changes

In general we aim for new features to be added in a backwards compatible way, but sometimes we will need to make breaking changes. This policy outlines how we will make and communicate these.

NOTE: Tekton Chains is working towards a formal beta release. Until then, all features are technically considered alpha (though we continue to do our best to retain backwards compatibility).
