Obtain the attestation:

REKOR_UUID=24296fb24b8ad77aede6ff3c84da87cdeda75e9dcf779abc736bf5423b8a4151bad8193f0c76dd15
rekor-cli get --uuid $REKOR_UUID --format json | jq -r .Attestation | jq .

Verify that all container images in the attestation are in the release file:

REKOR_UUID=24296fb24b8ad77aede6ff3c84da87cdeda75e9dcf779abc736bf5423b8a4151bad8193f0c76dd15

# 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 + ":v0.52.0@sha256:" + .digest.sha256')

# Download the release file
curl "$RELEASE_FILE" > release.yaml

# For each image in the attestation, match it to the release file
for image in $REKOR_ATTESTATION_IMAGES; do
  printf $image; grep -q $image release.yaml && echo " ===> ok" || echo " ===> no match";

Changes

Features

• ✨ Add taskrun/pipelinerun gauge metrics around resolving respective tasks/pipelines (#7094)

New gauge metrics are introduced that count the number of TaskRuns waiting for resolution of any Tasks they reference, as well as count the number of PipelineRuns waiting on Pipeline resolution, and lastly count the number of PipelineRuns waiting on Task resolution for their underlying TaskRuns.

• ✨ [TEP-0056]: Initial set of API refactors pertinent to Pipelines in Pipelines (#7055)

Added PipelineRef and PipelineSpec fields to PipelineTask, in lieu of TEP-0056

Fixes

• 🐛 fix: clean results when taskrun retries (#7126)

The taskrun will clean up the last task results before retrying.

• 🐛 Validate beta features for inline pipelines and tasks (#7079)

Bug fix: validate beta features in inline tasks/pipelines in the same way as referenced tasks/pipelines

• 🐛 Remove results annotations filtering (#7108)
• 🐛 fix an issue with InvalidMatrixParameterTypes along with updating the matrix example with additional validations (#7064)

Misc

• 🔨 Add configmap for tracing config (#6897)

Tracing endpoint configuration is now moved from environment variable to the configmap config-tracing. Tracing can be now configured dynamically without needing to restart the controller. Refer the example configuration provided as part of the ConfigMap for the configuration options and format.
