+If the environment variable YAZ_LOG is set, then it is used as a
+string indicating the default level of logging to use if not
+overridden by calls to yaz_log_init() or yaz_log_init_level(). If
+it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
+used as before. So, for example, to omit warnings from YAZ logging,
+ export YAZ_LOG=-warn
+
+cql_transform() now map structure and other attributes before indexes,
+so that index-specific structures and other attributes can override
+defaults. So now a combination of mapping specifications such as:
+ structure.* = 4=1
+ index.dc.date = 1=date-modified 4=5
+does the right thing.
+
+cql_transform() now also respects the "always" mapping specification,
+which establishes an initial set of attributes to be used for all
+terms except where overridden by more specific attributes associated
+with the index, relation or modifier.
+
+Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
+which mode to use; one of "post", "get" or "soap" (SRW, default).
+
+Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
+sequences where not read correctly. Fix by Rustam Usmanov.
+
+Updates to win/makefile which makes things compile happily with VS C 2005.
+
+--- 2.1.12 2006/02/01
+
+Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
+
+In ZOOM socket code, use select instead of poll on MacOSX.
+
+ZOOM-C now support client-side compilation of CQL into RPN that is
+sent to the server, enabling CQL to be used against all Z39.50
+servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
+ZOOM_query object, and submit it using ZOOM_connection_search().
+The CQL-to-RPN translation uses a configuration file, the name of
+which must be specified in the Connection's "cqlfile" option.
+
+ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
+function, which takes as its start-term parameter a ZOOM_query object
+(which may have had either CQL or RPN set into it).
