+Modified Zebra so that it works with ASN.1 compiled code for YAZ.
+
+Implemented EXPLAIN database maintenance. Zebra automatically
+generate - and update TargetInfo, DatabaseInfo, AttributeSetInfo
+and AttributeDetails records at this stage. The records may
+be transferred as GRS-1, SUTRS and 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.
