+## edge-19.8.3
+
+This edge release introduces a new `linkerd stat trafficsplits` subcommand, to
+show traffic split metrics. It also introduces a "Kubernetes cluster monitoring"
+Grafana dashboard.
+
+* CLI
+  * Added traffic split metrics via `linkerd stat trafficsplits` subcommand
+  * Fixed `linkerd uninject` not removing `linkerd.io/inject: enabled`
+    annotations
+  * Fixed `linkerd stat -h` example commands (thanks @ethan-daocloud!)
+* Controller
+  * Removed unauthenticated tap from the Public API
+* Proxy
+  * Added `request_handle_us` histogram to measure proxy overhead
+  * Updated the tap server to only admit requests from the control plane's tap
+    controller
+  * Fixed a bug where tap would stop streaming after a short amount of time
+  * Fixed a bug that could cause the proxy to leak service discovery resolutions
+    to the Destination controller
+* Web UI
+  * Added "Kubernetes cluster monitoring" Grafana dashboard with cluster and
+    containers metrics
+* Internal
+  * Updated `linkerd install` and `linkerd upgrade` to use Helm charts for
+    templating
+  * Pinned Helm tooling to `v2.14.3`
+  * Added Helm integration tests
+  * Added container CPU and memory usage to `linkerd-heartbeat` requests
+  * Removed unused inject code (thanks @alenkacz!)
