⚠️ Known Issues

• #4483 Implicit parameter mapping incorrectly passes params from the top-level Pipeline or PipelineRun to taskRef Pipeline Tasks. Mapping should only occur from top-level resource to Pipeline Tasks with in-line taskSpec. This issue only affects users with enable-api-fields: alpha in the feature-flags ConfigMap stored in the tekton-pipelines namespace.
