+* Fix service name deriving from a client class name in Request

+  failed gRPC response with a valid gRPC message.
+
+### 2.0.0
+
+* This release contains improved exception messages, that include the name of the service and a method that was
+  invoked but failed.
+* Breaking change: removal of the `Grphp\Client\Error::ERROR_METADATA_KEY` constant.
+
+### 1.0.0
+
+* This release contains an improvement to reporting an error status from gRPC stack by propagating it as part of the 
+  Status attached to the RequestException.
+* A breaking change to the config to require a scheme for a given base URI is introduced in order to fix certain 
+  situations where proxied request is sent to the service without a scheme causing request parsing failures.
