+
+New .abs directive, systag, that control where to put retrieval
+information. The directive takes two arguments: system tag, actual tag.
+System tag is one of : rank, sysno, size with the default actual
+rank, localControlNumber, size .
+
+--- 1.3.4 2002/11/26
+
+Perl Filter and Perl API. By Peter Popovics.
+
+For zebra.cfg, if no profilePath is specified, directory
+ (prefix)/share/idzebra/tab
+is used.
+
+Zebra Examples in examples . Zebra tests in test.
+
+Bug fix: sort index was not properly modified on
+record updates/deletes.
+
+Fix handling of character entities for sgml filter.
+
+Move data1 to Zebra (used to be part of YAZ).
+
+--- 1.3.3 2002/10/05
+
+Fix character encoding of scan response terms.
+
+Fix character decoding of scan request terms.
+
+Fix ESpec handling (requires YAZ 1.9.1)
+
+Fix searches for complete fields.
+
+--- 1.3.2 2002/09/09
+
+When name zebra is used in a filename or directory 'idzebra' is used
+instead to avoid confusion with GNU zebra (routing software).
+
+Zebra server stops with a fatal error if config file cannot be read.
+
+New config setting, followLinks, that controls whether update of files
+should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
+By default symbolic links are followed.
+
+Fix MARC transfer . MARC fields had wrong data for multiple fields.
+
+XML record reader moved from YAZ to Zebra, to make YAZ less
+dependant on external libraries.
+
+Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
+UCS4, ISO-8859-1. This means that Zebra does UNICODE even
+on systems that doesn't offer iconv.
+
+XML record reader supports external system entities.
+
+--- 1.3.1 2002/08/20
+
+New .abs-directive "xpath" that takes one argument: "enable"
+or "disable" to enable and disable XPath -indexing. If no "xpath"
+direcive is found in .abs-file , XPath-indexing is disabled to ensure
+backwards compatibility. For missing .abs-files XPath-indexing is
+enabled so that such records are searchable.
+
+Zebra warns about missing .abs-file only once (for each type).
+
+Fixed a bug in file update where already-inserted files could
+be treated as "new".
+
+--- 1.3.0 2002/08/05
+
+Zebra license changed to GNU GPL.
+
+XPath-like queries used when RPN string attributes are used, eg.
+ @attr 1=/portal/title sometitle
+ @attr 1=/portal/title[@xml:lang=da] danishtitle
+ @attr 1=/portal/title/@xml:lang da
+ @attr 1=//title sometitle
+
+Zebra uses UTF-8 internally:
+1) New setting "encoding" for zebra.cfg that specifies encoding for
+OCTET terms in queries and record encoding for most transfer syntaxes
+(except those that use International Strings, such as GRS-1).
+2) The encoding of International strings is UTF-8 by default. It
+may be changed by character set negotiation. If character set
+negotiation is in effect and if records are selected for conversion
+these'll be converted to the selected character set - thus overriding
+the encoding setting in zebra.cfg.
+3) New directive "encoding" in .abs-files. This specifies the external
+character encoding for files indexed by zebra. However, if records
+themselves have an XML header that specifies and encoding that'll be used
+instead.
+
+XML filter (-t grs.xml).
+
+Multiple registers. New setting in resource 'root' that holds base
+directory for register(s). A group a databases may be put in separate
+register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
+
+--- 1.1.1 2002/03/21
+
+Fixes for Digital Unix
+
+Implemented hits per term using USR:SearchResult-1.
+
+New Zebra API. Locking system re-implemented.
+
+--- 1.1.stable 2002/02/20
+
+Rank weight can be controlled with attribute type 9. Default
+value is 34. Recommended values between 1-36.
+
+--- 1.1 2001/10/25
+
+Updated for YAZ version 1.8.
+
+Added support for termsets - a result set of terms matching
+a given query. For @attr 8=<set> creates termset named <set>.
+
+Added support for raw retrieval. Element Set Name R forces the
+text filter which returns the record in its original form.
+
+Added numerical sort - triggered by structure=numeric (4=109).
+
+Remote record import using Z39.50 Extended Services and Segments.
+
+Fixed bug where updating a database with user-defined attributes
+could corrupt the register (bad storeKeys).
+
+Multi-threaded version.
+
+Fixed bug regarding proximity.
+
+Documentation updates.
+
+Fixed bug in record retrieval module that occured on 64-bit OSF
+architectures.
+
+--- 1.0.1 2000/2/10
+
+Fixed bug in makefile for WIN32.
+
+Fixed bug in configure script - used bash-specific features.
+
+--- 1.0 1999/12/10
+
+Added support for multiple records in one file for filter grs.sgml.
+
+Changed record index structure. New layout is incompatible with
+previous releases. Added setting "recordcompression" to control
+compression of records. Possible values are "none" (no
+compression) and bzip2 (compression using libbz2).
+
+Added XML transfer syntax support for retrieval of structured records.
+Schema in CompSpec is recognised in retrieval of structured records.
+
+Changed Tcl record filter so that it attemps to read <filt>.tflt. If
+that fails, the filter reads the file <filt>.flt (regx style filter).
+
+Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
+Zebra's configure script automatically attempts to locate Tcl. For
+manual Tcl configuration use option --with-tclconfig=<path> to specify
+where Tcl's library files are located.
+
+Implemented "compression" of Dictionary and ISAM system. Dictionary
+format HAS changed.
+
+Added "tagsysno" directive to zebra.cfg to control under which tag the
+system ID is placed. Use tagsysno: 0 to disable Zebra's system number
+entirely.
+
+Added "tagrank" as above.
+
+Changed file naming scheme for register files from <name>.mf.<no> to
+<name>-<no>.mf.
+
+Implemented "position"-flag for register type (as defined in
+default.idx). When set to zero no position (or seqence number) is
+saved in register for each word occurrence, thus saving some register
+space.
+
+Implemented database mapping. Using mapdb one can specify a database
+to be mapped to one or more physical databases. Usage:
+mapdb <fromdb> <todb> ..
+
+Added SOIF-filter. Thanks to Peter Valkenburg.
+
+For the regx-filter "end element -record" may trigger a mark-of-record
+if outer level is reached.
+
+Tag sets may be typed in the reference to it. From the .abs-file the
+"tagset" directive takes a third optional integer type for the tag set
+referenced. From a .tag-file the "include" directive takes a third
+optional type as well. The old "type" directive in the tag set itself
+is still recognized but acts as the default type for the tag set.
+
+Zebra supports the specification of arbitrary attributes sets, schemas
+and tag sets, because of the change in YAZ' OID management system.
+
+Fixed bug in Sort that caused it NOT to use character mapping as it
+should.
+
+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
+where 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 about attribute
+sets, available attributes, etc.. 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 on 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.
-Moved towards generic character mapping. Type w, p uses
-string.chr, u uses urx.chr and n uses numeric.chr.
-
Added support for C++, headers uses extern "C" for public definitions.
-New filter grs.marc.<syntax> that reads MARC records in the ISO2709
-format. <syntax> refers to the abstract syntax.
-
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).
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.
