Linkerd - edge-22.8.1

edge-22.8.1

This releases introduces default probe authorization. This means that on
clusters that use a default deny policy, probes do not have to be explicitly
authorized using policy resources. Additionally, the
policyController.probeNetworks Helm value has been added, which allows users
to configure the networks that probes are expected to be performed from.

Additionally, the linkerd authz command has been updated to support the policy
resources AuthorizationPolicy and HttpRoute.

Finally, some smaller changes include allowing to disable linkerd-await on
control plane components (using the existing proxy.await configuration) and
changing the default iptables mode back to legacy to support more cluster
environments by default.
