 ### Emissary-ingress and Ambassador Edge Stack
 
-- Change: The envoy version included in Emissary-ingress has been upgraded from 1.17 to latest patch
-  release of 1.22. This provides $produceName$ with the latest security patches, performances
-  enhancments, and features offered by the envoy proxy. One notable change that will effect users is
-  the removal of support for V2 tranport protocol. See below for more information.

 - Change: Emissary-ingress can no longer be made to configure Envoy using the v2 xDS configuration
   API; it now always uses the v3 xDS API to configure Envoy.  This change should be mostly invisible
