#### Revisions

Control plane revisions allow deploying multiple versions of the control plane in the same cluster.
This allows safe [canary upgrades](https://istio.io/latest/docs/setup/upgrade/canary/)

revision: my-revision-name

				injectLabel = fmt.Sprintf(`istio.io/rev: "%v"`, t.Settings().Revisions.Default())
			}

			templateParams := map[string]string{
				"imagePullSecret": t.Settings().Image.PullSecret,
				"injectLabel":     injectLabel,

func NewLeaderElection(namespace, name, electionID, revision string, client kube.Client) *LeaderElection {
	return newLeaderElection(namespace, name, electionID, revision, false, false, client)
}

// NewPerRevisionLeaderElection creates a *per revision* leader election. This means there will be one leader for each revision.

## Upgrade Planning

apiVersion: release-notes/v2
kind: feature
area: installation
releaseNotes:
  - |
    **Removed** the `istioctl experimental revision` command. Revisions can be inspected by the stable `istioctl tag list` command.
  - |
    **Removed** the `installed-state` `IstioOperator` that was created when running `istioctl install`. This previously provided only a snapshot
    of what was installed.
