+0.3.0 (Mar 26, 2020)
+====================
+
+This is the first release of Envoy Mobile Lyft is using in a production application! 🎉
+
+Since early November, when the team tagged v0.2.0, we have been hard at work to stabilize the library,
+and harden it via experiments with Lyft's Alpha and Beta releases. We have released Lyft's production
+binaries with Envoy Mobile for a couple weeks now, and are starting to expose a percentage of our
+production clients to Envoy Mobile with this release.
+
+Since v0.2.3 we have largely focused on observability:
+
+- Adds improved logging (#701, #702, #722)
+- Adds basic stats for retries #718)
+- Adds ``x-envoy-attempt-count`` response header (#751)
+- Adds visibility over `virtual clusters <https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/route/v3/route_components.proto#config-route-v3-virtualcluster>`_ (#768, #771)
+
+Additional changes:
+
+- Fixes trailers missing on iOS (#703)
+- Adds ability to set DNS failure refresh rate (#714)
+- Adds docs on the EnvoyClientBuilder (#745)
+
 0.2.3 (Feb 21, 2020)
