There have been - and are - different versions of the rsync protocol.  I 
think it is currently on version twenty-something.  The difference is 
that rsync exchanges the  protocol version with it's partner and 
continues to interoperate with previous versions.

Just about every network protocol has been revised. Most of them 
continue to work with whatever features older revisions supported. If a 
program gets something that simple wrong, how much can you trust it with 
your data?
