+## Bug fixes
+
+* **Fixed** root certificate rotation in Citadel to reuse values from the expiring root certificate into the new root certificate ([Issue 19644](https://github.com/istio/istio/issues/19644)).
+* **Fixed** telemetry to ignore forwarded attributes at the gateway.
+* **Fixed** sidecar injection into pods with containers that export no port ([Issue 18594](https://github.com/istio/istio/issues/18594)).
+* **Added** telemetry support for pod names containing periods ([Issue 19015](https://github.com/istio/istio/issues/19015)).
+* **Added** support for generating `PKCS#8` private keys in Citadel agent ([Issue 19948](https://github.com/istio/istio/issues/19948)).
+
+## Minor enhancements
+

+* **Added** support for setting the Mesh UID in the Stackdriver Mixer adapter ([Issue 17952](https://github.com/istio/istio/issues/17952)).
