+Added support for CCL queries in Z39.50 queries sent to the GFS (and
+therefore in Zebra and in SimpleServer-based applications). The new
+<ccl2rpn> element in a GFS configuration file, if present, names a CCL
+qualifier file used to transform incoming CCL queries into Type-1 RPN,
+which is passed into the back-end search callback function.
+
+Added support for HTTP Basic authentication in clients: the SRU/W
+codec encodes the username/password elements of the PDU structure
+appropriately, and these may be set using the "user" and "password"
+options in ZOOM-C applications (the same options that are used for
+Z39.50 authentication).
