+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.
+
+Reduced disk space for saved keys (storeKeys = 1).
+
+Added optional, physical ANY (key replication)
+
+Implemented proximity operator in search.
+
+Bug fix: the path name buffers used by file match traversal routines
+have been extended to support long file names.
+
+New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
+configuration file. The resulting register without "storeKeys" is about
+half the size, and the memory used by zebraidx during phase 2 (merge) is
+reduced to a minimum.
+
+Reworked the way Regexp-2 queries with error tolerance are handled and
+specified. The documentation has been updated accordingly.
+
+Bug fix: Zebrasrv didn't search correctly when queries contained masking
+characters. This bug was introduced in 1.0a8.
+
+Zebrasrv now tag records with the proper database name.
+
+New settings, memMax and keyTmpDir.
+
+Changed name of setting lockDir (previously called lockPath) and
+setTmpDir (previously called tempSetPath).
+
+Generalized and changed record type specifications. In short, there are:
+ text plain SUTRS
+ grs.sgml structured, "SGML-like" syntax
+ grs.regx.<filter> structured, Regular expression filter
+ grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
+ is the name of an abstract syntax file.
+Bug fix: Result sets weren't sorted in operations involving boolean
+operations with "ranked" operands.
+
+--- 1.0a8 1996/6/6
+
+Added national character-handling subsystem.
+
+Various fixes.
+
+Small modifications to input filters and profiles.
+
+Added support for SOIF syntax (with private OID).
+
+--- 1.0a7 1996/5/16
+
+Fixed buffer-size problem in indexing.
+
+Added compression to temporary files for updating.
+
+Added phrase registers.
+
+Added dynamic mapping of search attribute to multiple termlists (ANY).
+
+Scan support in multiple databases/registers.
+
+Configuration settings are case-insensitive and single dash (-)
+characters are ignored in comparisons.
+
+The index processing ignores empty files - warning given.
+
+New option to zebraidx (-V) displays version information.
+
+--- 1.0a6 1996/2/24
+
+Fixed problem in file-update system.
+
+Fixed problem in shadow system; register was sometimes corrupted after
+a commit operation.
+
+--- 1.0a5 1996/2/10
+
+Fixed problems in the ISAM subsystem. Caused difficulties when updating
+existing registers.
+
+Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
+the rank and record number.
+
+Fixed bug in the isam subsystem - caused a malfunction when accessing
+words which occurred more than 10000 times.
+
+Distribution should now include YAZ (Z39.50 protocol stack) to simplify
+installation.
+
+Server can now run under inetd. Use option -i, and -w <directory> to
+set working directory to desired location.
+
+New zebraidx command: clean - removes temporary shadow files.
+
+Fixed bug in ISAM system. Occurred rarely during register updates.
+
+Logging during index merge phase is improved. The remaining running
+time is estimated.
+
+Temporary files generated by zebraidx are removed after each run.
+
+Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
+when doing scan operations in dictionaries with European characters.
+
+--- 1.0a4 1996/01/11
+
+A whole slew of updates, to make the first publicized release. Get the doc
+and check it out.
+
+--- 1.0a3 1995/12/06
+
+Memory-problems in ISAM fixed. More blocktypes added to the default setup
+to increase performance on larger databases.
+
+Various minor changes in data management system.
+
--- 1.0a2 1995/12/05
A couple of portability-problems resolved.
