2.0.2 compatible with 2.0.1?

[Brent A Nelson <brent@xxxxxxxxxxxx>]

I tried upgrading one node in my distributed afr cluster to the 2.0.2 
tar.gz currently undergoing testing, and I found that the new servers were 
refusing connections from 2.0.1 clients, and the 2.0.2 clients didn't seem 
to be talking to the old 2.0.1 servers. Is this intentional, or did 
someone unnecessarily increase the protocol version so that the two ends 
incorrectly concluded that they were incompatible, or ...?

Thanks,

Brent
