# Tekton v1.18.0

> CI/CD & App Delivery · 2026-10-29

A maintenance release adds a step error-handling option and includes correctness fixes, stricter label immutability, and routine dependency updates. It also fixes published image timestamps, Tekton bundle parsing, and early cleanup for child pipelines.

## Check if affected
- **[breaking]** Immutable controller-managed labels
  - Applies if you set `tekton.dev/pipeline`, `tekton.dev/pipelineTask`, or `tekton.dev/pipelineRun`.
  - The controller-managed labels `tekton.dev/pipeline`, `tekton.dev/pipelineTask`, and `tekton.dev/pipelineRun` are immutable once set. Users cannot change them when updating a `PipelineRun` or `TaskRun`.
