In addition, mongos now needs to start sending setShardVersion (0,0) before sending requests to unsharded collections, otherwise, the connection will never have ShardedConnectionInfo and no version checking will take place for that connection. In other words, if the collection was actually sharded, the shard will not throw a stale shard version exception.
