 ### Changes to service descriptors
 
 Connect now relies on service descriptors generated by the Protobuf-ES v2 plugin
-`protoc-gen-es` and no longer generates code itself. The descriptors still provide
-the same functionality - typed metadata for clients and servers - but in a slightly
-different form. Types and properties have changed to consolidate the reflection
-APIs and to provide new features.
