+
+## Known issues
+
+- Pilot may deadlock when using [`istioctl proxy-status`](/docs/reference/commands/istioctl/#istioctl-proxy-status) to get proxy synchronization status.
+  The work around is to *not use* `istioctl proxy-status`.
+  Once Pilot enters a deadlock, it exhibits continuous goroutine growth eventually running out of memory.
+
+## Networking
+
+- Fixed the lack of removal of stale endpoints causing `503` errors.
+
+- Fixed sidecar injection when a pod label contains a `/`.
+
+## Policy and telemetry
+
+- Fixed occasional data corruption problem with out-of-process Mixer adapters leading to incorrect behavior.
+
+- Fixed excessive CPU usage by Mixer when waiting for missing CRDs.
