🎉 When expressions and webhook probes! 🎉

Installation one-liner

kubectl apply -f https://storage.googleapis.com/tekton-releases/pipeline/previous/v0.16.0/release.yaml

📣 The tekton-pipelines-controller and tekton-pipelines-controller are now configured to run as a non-root user. (#2967)

✨ Liveness and readiness probes are available for webhook. (#3162)
✨ To run a Task only when certain criteria are met, it is now possible to guard task execution using
the when field, which allows you to list a series of references to WhenExpressions that contain
an Input, an Operator and Values. The valid Operators are in and notin. The WhenExpressions are ANDed. (#3135)
✨ Update step statuses on TaskRun in event of cancellation or timeout (#3088)
✨ fix(substition): fix configmap and secret volume param substition (#3071)
✨ User can access the uid of the PipelineRun that a Pipeline is running in using context.pipelineRun.uid, User can access the uid of the TaskRun that a Task is running in using context.taskRun.uid, All context variables that are supported so far are now validated. (#3017)
✨ Adding support for git-lfs repositories in git-init by adding the package in the git-init image (#3006)
✨ The TaskRun.Status.ResourcesResult field now contains a URL for Git and Image PipelineResources, containing the URL of the resource data. (#2975)
✨ Pipeline authors can now specify metadata while embedding tasks (using taskSpec) into their pipeline. (#2826)

🚨 Conditions CRD deprecated, use WhenExpressions instead. (#3135)
🚨 PipelineRun.Spec.ServiceAccountNames is being deprecated in favor of PipelineRun.Spec.TaskRunSpec[].ServiceAccountName (#3028)

None!

🐛 Fixes a bug with validation for the Affinity Assistant when the same PVC is used for multiple workspaces but with different subPaths (#3099)
🐛 Fix an issue where PipelineRuns would pass validation even when a workspace binding was missing required volume info. (#3096)
🐛 When a TaskRun or PipelineRun completes, the go routine waiting for it to timeout will now stop (as it was designed to do!) instead of always re-reconciling (#3078)
🐛 The tekton-pipelines-controller and tekton-pipelines-controller are now configured to run as a non-root user. To match these reduced requirements, the tekton-pipelines PodSecurityPolicy updates its runAsUser rule to use MustRunAsNonRoot and is further tightened-up to only allow "use" in the tekton-pipelines namespace. (#2967)
🐛 Use ko:// in e2e tests to exercise current code 🙃 (#2902)
