Changes

Features

  • ✨ TEP-0090: Matrix - Context Variables (#4689)

    Parameters in Matrix support Context Variables. Note that Matrix is not yet fully functional.

  • ✨ Implement CloudEvents for Runs (#4663)

    Tekton Pipelines can now generate CloudEvents for Runs.
    This feature is disabled by default. It can by enable by setting a sink URL and flipping the new feature flag "send-cloudevents-for-runs" to "true"

  • ✨ Add CloudEvents for Run definitions (#4659)

    CloudEvents for Run have been defined, but they are not sent yet.

  • ✨ TEP-0090: Matrix - API Change and Feature Flag (#4600)

    Added syntax support for Matrix as an alpha feature. It is still in a very early stage of development and is not yet fully functional.
