Yes, the handshake between client and server just checks that the
string "<version major>.<version minor>" is the same on the client and
server. There typically shouldn't be protocol changes between release
candidates, so this level of version checking should normally be
reasonable. Ideally, we would like a 5.2.0 client to be able to
connect to a 5.2.1 server and vice versa, so connections between
different RCs should be possible, too.

Obviously, that didn't happen in this release candidate phase. Between
RC3 and RC4 there were some options added to the NetCDF reader.
Changing proxy properties changes the client/server protocol and makes
them incompatible, IIUC.
