 ## Summary
 
-The main features of this release is the new base class for API clients, gRPC exception wrappers and a new utility function to call stub methods.
+<!-- Here goes a general summary of what this release is about -->
 
 ## Upgrading
 
-- `channel.parse_grpc_uri()` takes an extra argument, the channel type (which can be either `grpclib.client.Channel` or `grpcio.aio.Channel`).
+<!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
 
 ## New Features
 
-- Add a `exception` module to provide client exceptions, including gRPC errors with one subclass per gRPC error status code.
-- `channel.parse_grpc_uri()` can now be used with `grpcio` too.
-- A new `BaseApiClient` class is introduced to provide a base class for API clients. It is strongly recommended to use this class as a base class for all API clients.
-- A new `call_stub_method()` function to simplify calling stub methods, converting gRPC errors to `ApiClientError`s, checking if the client is connected and optionally wrapping the response.
