+
+yaz-ztest: Use hash for fake hit count. Before, random number was used.
+This is problematic for unit tests using yaz-ztest. This patch also makes
+a hash for CQL queries. For RPN, any term with a leading digit will be
+treated as pseudu hit count (to force any particular hit count by a client).
+
+yaz-ztest: return unique MARC dummy records. Beyond record offset
+24, the author surname is patched with offset to make all records
+unique.
+
+COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
+on system wide default (/proc/sys/net/ipv6/bindv6only).
+@4 binds to IPV4 only. @6 binds to IPV6 only.
+
+Update CQL API documentation a bit
+
+CQL: don't accept extra terms for queries. Makes the CQL parser
+stricly conformant to the standard.

+
+GFS: scan handler gets extra_args from request and may return extra
+response data . That's for SRU only.
+
+Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
+

+
+New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
+
+OPACXML: sync spelling of availabilityDate in XML to that of Schema
+opaxxml.xsd. The schema had the correct spelling of this member always.
+The ASN.1 was mis-spelled and still is (API change) - we are
+not changing this. However, the OPAC to XML conversion had yet
+*another* typo.
+
+GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
+element.
+
+New function, z_ext_record_oid_nmem, which is similar to
+z_ext_record_oid but takes NMEM rather than ODR
+
+--- 4.2.49 2013/01/18
+
+ICU: New conversion element 'join' which joins tokens into one
+with a custom character given by rule attribute.
