## edge-19.6.4

This release adds support for the SMI [Traffic Split](https://github.com/deislabs/smi-spec/blob/master/traffic-split.md)
API. Creating a TrafficSplit resource will cause Linkerd to split traffic
between the specified backend services. Please see [the spec](https://github.com/deislabs/smi-spec/blob/master/traffic-split.md)
for more details.

* CLI
  * Added a check to `install` to prevent installing multiple control planes
    into different namespaces
  * Added support for passing a URL directly to `linkerd inject` (thanks
    @Pothulapati!)
  * Added the `--all-namespaces` flag to `linkerd edges`
* Controller
  * Added support for the SMI TrafficSplit API which allows users to define
    traffic splits in TrafficSplit custom resources
* Web UI
  * Improved UI for Edges table in dashboard by changing column names, adding a
    "Secured" icon and showing an empty Edges table in the case of no returned
    edges
