Subversion version compatability

["Oxley, David" <Da...@workplace-systems.plc.uk>]

We have just upgraded our server to 0.29.0, but our developers are
distributed across the country and they may be running earlier versions. A
couple of questions:
1. Will using an earlier version cause any corruption in the repository?
2. What problems will our developers encounter?
3. Can't the client be changed to output an error if it tries to talk to an
incompatible server? (i.e. The server is running 0.29.0, please upgrade your
client to 0.28.0 or above.)

Cheers.
Dave.

Corruption?  Not at all.  You might get network errors.

Network failures, due to changing network protocols.  A 0.29 server is
only "guaranteed" (in the sense of tech support) to work with a 0.29
or 0.28 client.  It may or may not work with an eariler client.

This request has come up over and over, and has (in my memory) led to
long arguments about how to implement this... but never bore any
fruit.  :-(
