 `nats-streaming` is a high performance streaming server for the NATS Messaging System.
 
+# Backward compatibility note
+
+Note that the Streaming server itself is backward compatible with previous releases, however, v0.15.0+ now embeds a NATS Server 2.0, which means that if you run with the embedded NATS server and want to route it to your existing v0.14.3- servers, it will fail due to NATS Server routing protocol change. You can however use v0.15.0+ and connect it to existing NATS cluster and therefore have a mix of v0.15.0 and v0.14.3- streaming servers.

If you need to specify any additional argument, or modify these options, you need to specify the executable name as this:
