+Changed the way PQF queries are encoded in SRU GET/POST. PQF search
+before: x-pquery=pqf . PQF search now: query=pqf&x-querytype=pqf . This
+makes the SRU request more conformant because the required query parameter
+is always present. PQF scan before: x-pScanClause=pqf . PQF scan now:
+scanClause=pqf&x-querytype=pqf .
+
+For the generic frontend server, the maximum record size is used as maximum
+size of incoming packages (SRU + Z39.50). The value until was previously
+only used in Z39.50 Init negotiation and, later, in a session controlled
+sizes of records returned. This is controlled using -k option. It can be
+specified, per server, with element maximumrecordsize in YAZ' GFS XML config.

TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
