+## Major Changes
+
+### New command line flags and behavior
+
+#### VTGate GRPC stream execute session flag `--grpc-send-session-in-streaming`
+
+This flag enables transaction support on `StreamExecute` api.
+One enabled, VTGate `StreamExecute` grpc api will send session as the last packet in the response.
+The client should enable it only when they have made the required changes to expect such a packet.
+
+It is disabled by default from v17.0.3.
+
+This was a breaking change when v17.0.0 was released was causing upgrade issue for client
+who relied on a certain behaviour of receiving streaming packets on `StreamExecute` call.

--gateway_initial_tablet_timeout duration At startup, the tabletGateway will wait up to this duration to get at least one tablet per keyspace/shard/tablet type (default 30s)
