+### Breaking
+
+Introduce API breaking that should facilitate maintenance and compilation errors.
+
+- Removed generic interceptor types from `GeyserGrpcClient`
+- Replaced `impl Sink<SubscribeRequest, Error = mpsc::SendError>` with `SubscribeRequestSink` type.
+- Replaced `impl Sink<SubscribeDeshredRequest, Error = mpsc::SendError>` with `SubscribeDeshredRequestSink` type.
+- Replaced `impl Stream<Item = Result<SubscribeUpdate, Status>>` with `GeyserStream` type.
+- Replaced `impl Stream<Item = Result<SubscribeUpdateDeshred, Status>>` with `DeshredStream` type
+- `SubscribeRequestSink`now returns `SubscribeRequestSinkError` instead of `mpsc::SendError`.
+- Removed `GeyserGrpcClientError::SubscribeSendError` variant as no code branch could raise this error.
