This release introduces new experimental CLI commands for querying metrics using
the Service Mesh Interface (SMI) and for multi-cluster support via service
mirroring.
If you would like to learn more about service mirroring or SMI, or are
interested in experimenting with these features, please join us in
[Linkerd Slack](https://slack.linkerd.io) for help and feedback.
* CLI
* Added experimental `linkerd cluster` commands for managing multi-cluster
service mirroring
* Added the experimental `linkerd alpha clients` command, which uses the
smi-metrics API to display client-side metrics from each of a resource's
clients
* Added retries to some `linkerd check` checks to prevent spurious failures
when run immediately after cluster creation or Linkerd installation
