+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 (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. 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 when using 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.
+
+--- 1.0b1 1998/1/29
+
+Simple ranked searches now return correct number of hits.
+
+The test option (-s) only makes a read-lock on the index as well
+as using read-only operations anywhere.
+
+Moved towards generic character mapping. Configuration file default.idx
+specifies character map files for register types w, p, u, etc.
+
+Implemented "begin variant" for the sgml.regx - filter.
+
+Fixed a few memory leaks.
+
+Added support for C++, headers uses extern "C" for public definitions.
+
+Bug fix: The show records facility (-s) only displayed information for
+the first record in a file (and not for every record in the file).
+
+Added option "-f <n>" to limit the logging of record operations. After
+<n> records has been processed no logging is performed (unless errors
+occur).
+
+Bug fix: the compressed ISAM system didn't handle update operations
+correctly.
+
+Added setting, "maxResultSetSize", to hold the number of records to 
+save in a result set.
+
 Bug fix: Complete phrase did't work for search operations.
 
 Bug fix: temporary result sets weren't deleted.
