+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).
