+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

 refer to index type "s" which is specified as "sort" in the default.idx
