------------------------------------------------------------------------------
  ''Owen, you seem to be extending the ["Roadmap"]'s compatibility requirements to RPC protocols,
is that right?  Clients must be back-compatible with older servers and servers must be back-compatible
with older clients.  If so, perhaps we should vote on this new policy and update ["Roadmap"]
accordingly.  We could even start enforcing it before 1.0, so that, e.g., 0.20's protocols
would need to be back-compatible with 0.19's but 0.21's would not.  --DougCutting''
  
  ''Doug, This is a subtle issue: Here we are talking about new client application code calling
old methods on the !FileSystem class (not the RPC methods). This is in addition to the rpc
compatibility issue. --!SanjayRadia''
+ 
+ ''Sanjay, How does 'new client application code calling old methods on the !FileSystem'
differ from our current back-compatibility requirements?  --DougCutting''
  
  Question: Does the release number really matter?  Should we just keep adding features, improving
back-compatibility, etc?  Our ["Roadmap"] currently defines what a major release means.  Does
this need updating?  -- !DougCutting
