edge-21.8.2
This edge release continues the policy work by adding a new controller, written
in Rust, to expose a discovery API for inbound server policies. Apart from
that, this release includes a number of changes from external contributors; the
linkerd-jaeger helm chart now supports passing arguments to the Jaeger
container through the chart's values file. A number of unused functions and
variables have been also removed to improve the quality of the codebase.
Finally, this release also comes with changes to the proxy's outbound behavior,
a new extensions page on the dashboard, and support for querying service
metrics using the authority label in linkerd viz stat.
