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.

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 " to limit the logging of record operations. After + 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. + +Reduced disk space for saved keys (storeKeys = 1). + +Added optional, physical ANY (key replication) + Implemented proximity operator in search.
