+For the regx-filter "end element -record" may trigger a mark-of-record
+if outer level is reached.
+
+Tag sets may be typed in the reference to it. From the .abs-file the
+"tagset" directive takes a third optional integer type for the tag set
+referenced. From a .tag-file the "include" directive takes a third
+optional type as well. The old "type" directive in the tag set itself
+is still recognized but acts as the default type for the tag set.
+ 
+Zebra supports the specification of arbitrary attributes sets, schemas
+and tag sets, because of the change in YAZ' OID management system.
+
+Fixed bug in Sort that caused it NOT to use character mapping as it
+should.
+
+Zebra now uses GNU configure to generate Makefile(s).
+
+Added un-optimised support for left and left/right truncation attributes.
+
+Added support for relational operators on text when using RPN queries.
+
+Added support for sort specifications in RPN queries. Type 7 specifies
+'sort' where value 1=ascending, value 2=descending. The use attribute
+specifies the field criteria as usual.  The term specifies priority
+where 0=first, 1=second, ...
+
+Changed the way use attributes are specified in the recordId
+specification.
+
+Maximum number of databases in one Zebra register increased.
+
+New setting, databasePath, which specifies that first directory during
+update traversal is the database name (instead of a fixed one).
+
+New setting, explainDatabase, which specifies that databases are
+EXPLAIN aware.
+
+Modified Zebra so that it works with ASN.1 compiled code for YAZ.
+
+Implemented EXPLAIN database maintenance. Zebra automatically
+generate - and update CategoryList, TargetInfo, DatabaseInfo,
+AttributeSetInfo and AttributeDetails records at this stage. The
+records may be transferred as GRS-1, SUTRS or Explain.
+
+Fixed register spec so that colon isn't treated as size separator
+unless followed by [0-9+-] in order to allow DOS drive specifications.
+
+Fixed two bugs in ISAMC system.
+
+Changed the way Zebra keeps its maintenance information about attribute
+sets, available attributes, etc.. Records in "SGML" notation using an
+EXPLAIN schema is now used when appropriate.
+
+Bug fix: Index didn't handle update/insert/delete of the same record
+(i.e. same recordId) in one run (one invocation of zebraidx). Only the
+first occurence of a record is considered.
+
+Most searches now return correct number of hits.
+
+New modular ranking system. Interested programmers are encouraged to
+inspect rank1.c and improve the algorithm.
+
+Bug fix: Lock files weren't removed as they should on NT.
+
+Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
+specify a "sort register". Refer to the gils sample records which refer
+to index type "s" which is specified as "sort" in the default.idx file.
+Each sort criteria can either be Ascending or Descending and at most
+three sort elements can be specified.  
+
+Bug fix: Character mapping didn't work for text files.

 Simple ranked searches now return correct number of hits.
