Release Notes

konflux-ci/build-definitions (quay.io/konflux-ci/tekton-catalog/task-build-image-index)

v0.3

Changed

• The task now uses konflux-build-cli for the build step instead of an inline bash
  implementation. This provides more robust error handling and simplified maintenance.
• When ALWAYS_BUILD_INDEX is false and multiple images are provided, the task now
  creates an image index instead of failing. The previous behavior (failing with an error)
  was not useful.
• Image reference validation is now stricter and will fail earlier for invalid formats.

Removed

• COMMIT_SHA parameter (was not used by the task implementation)
• IMAGE_EXPIRES_AFTER parameter (was not used by the task implementation)

Added

• Started tracking changes in this file.

Hi @red-hat-konflux-kflux-prd-rh02[bot]. Thanks for your PR.

I'm waiting for a openshift-knative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
