## edge-19.6.1

* CLI
  * Fixed an issue where, when Linkerd is installed with `--ha`, running
    `linkerd upgrade` without `--ha` will disable the high availability
    control plane
  * Added a `--init-image-version` flag to `linkerd inject` to override the
    injected proxy-init container version
* Controller
  * Added multiple replicas for the `proxy-injector` and `sp-validator`
    controllers when run in high availability mode (thanks to @Pothulapati!)
* Proxy
  * Fixed a memory leak that can occur if an HTTP/2 request with a payload
    ends before the entire payload is sent to the destination
* Internal
  * Moved the proxy-init container to a separate `linkerd/proxy-init` Git
    repository
