I disagree that this is a change. RFC 1035 allows the server to close the connection at any time to reclaim resources. It specifies a generous idle time, but clients cannot assume that this is guaranteed - the server might be restarted, etc. RFC 1035 also specifies that TCP connections can be closed abruptly, e.g. with a RST. Clients must cope with this. A client is buggy if it does not have a mechanism to retry queries that failed because of a broken TCP connection.
