Announcing Linkerd2 edge-19.6.3

Kevin Leimkuhler
 

Hello Linkerd fans!

This is an edge release of Linkerd! The latest stable release is stable-2.3.2.

To install this edge release, run: `curl https://run.linkerd.io/install-edge | sh`

* CLI
  * Updated `linkerd check` to validate the caller can create
    `PodSecurityPolicy` resources
* Controller
  * Default the mutating and validating webhook configurations `sideEffects` 
    property to `None` to indicate that the webhooks have no side effects on
    other resources (thanks @Pothulapati!)
* Proxy
  * Added the `NET_RAW` capability to the proxy-init container to be compatible
    with `PodSecurityPolicy`s that use `drop: all`
  * Fixed the proxy rejecting HTTP2 requests that don't have an `:authority`
  * Improved idle service eviction to reduce resource consumption for clients
    that send requests to many services
* Web UI
  * Removed the "Debug" page from the Linkerd dashboard while the functionality
    of that page is being redesigned
  * Added an Edges table to the resource detail view that shows the source,
    destination name, and identity for proxied connections

As always, we're excited to hear your feedback. Please try the new release and 
send questions/comments to this mailing list, and report bugs via GitHub.
