Obtain the attestation:

RELEASE_FILE=https://infra.tekton.dev/tekton-releases/pipeline/previous/v1.16.0/release.yaml
REKOR_UUID=108e9186e8c5677a13e773b2ae0f6c52943d2b44a284030efb9b43068a9927a698b4799e13342b14
Obtains the list of images with sha from the attestation
REKOR_ATTESTATION_IMAGES=$(rekor-cli get --uuid "$REKOR_UUID" --format json | jq -r .Attestation | jq -r '.subject[]|.name + ":v1.16.0@sha256:" + .digest.sha256')
Download the release file
curl -L "$RELEASE_FILE" > release.yaml

for image in $REKOR_ATTESTATION_IMAGES; do
printf $image; grep -q $image release.yaml && echo " ===> ok" || echo " ===> no match";
done

Upgrade Notices

• 🚨 set-security-context enabled by default

action required: set-security-context now defaults to true and applies only to Tekton-injected TaskRun containers and Affinity Assistants (#9589, #10680). User-defined Steps and Sidecars must supply their own restricted-compatible security contexts. If the generated security contexts are incompatible with your images or Kubernetes implementation, set set-security-context to "false".

Changes

Features

• ✨ feat(tracing): add spans for task parameter and workspace substitution #9801 (#10271)

Tekton Pipeline Releases

Release Frequency

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

• Versions are numbered according to semantic versioning: vX.Y.Z
• A new release is produced on a monthly basis
• Four releases a year are chosen for long term support (LTS). All remaining releases are supported for approximately 1 month (until the next release is produced)
  • LTS releases take place in January, April, July and October every year
  • The first Tekton Pipelines LTS release will be v0.41.0 in October 2022
  • Releases happen towards the middle of the month, between the 13th and the 20th, depending on week-ends and readiness

Tekton Pipelines produces nightly builds, publicly available on gcr.io/tekton-nightly.

Transition Process

Before release v0.41 Tekton Pipelines has worked on the basis of an undocumented support period of four months, which will be maintained for the releases between v0.37 and v0.40.

Release Process

Tekton Pipeline releases are made of YAML manifests and container images. Manifests are published to cloud object-storage as well as [GitHub][tekton-pipeline-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 Pipeline [release process][tekton-releases-docs]
