• 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

Transition Process

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].
