-Experimental segment facility (for matching of words within one
-field/segment).
+--- 2.0.24 2008/01/18
+
+Fixed some memory violations for ICU enabled indexing that could be
+triggered by long phrases.
+
+Enable ICU on Windows. Thanks to Tumer Garip for makefile patches.
+
+Fixed bug #2002: Zebra crashes during merge using ICU indexing.
+
+--- 2.0.22 2007/12/20
+
+Handle encoding errors for strings passed to ICU. (assert was
+thrown earlier).
+
+Added zebraidx command, adelete, which attempts to delete records.
+It's like 'delete', but does not fail if a record does not exist.
+
+--- 2.0.20 2007/12/19
+
+Added experimental support for faceted results. This is implemented
+as a special retrieval on a result set and is triggered using element
+set name zebra::facet::f1:t1,f2,t2,.. which will return terms and
+hit counts for field f1, type t1, field f2, type t2, .. The returned
+data is packed as XML or SUTRS depending on record syntax.
+
+Added support for Unicode-based indexing using ICU. This allows
+locale specific scanning, sorting. The implementation is based on
+the ICU utility part of YAZ 3.0.16 and later. See the manual as well
+as the examples/marcxml for an example of the use of ICU.
+
+--- 2.0.18 2007/09/19
+
+Fixed bug with scan and staticrank enabled. Bug introduced in 2.0.16.
+
+--- 2.0.16 2007/09/12
+
+Scan now returns a displayTerm which closer to the original word/phrase
+from original record.
+
+Added snippet support. Element set name zebra::snippet will make
+Zebra return an XML record with snippets (terms around matching terms).
+
+Fixed bug #1142: Non-indexed but listed attributes issues diagnostic.
+
+Fixed bug #1131: Missing value-of data in DOM filter.
+
+Fixed bug #1049: zebra.cfg lines with leading space are ignored.
+
+Fixed bug #1128: sortmax not honored.
+
+Fixed bug #1121: Crash for some searches with customized string.chr.
+
+--- 2.0.14 2007/05/09
+
+Zebra uses the YAZ 3 API. Note that this changes the Zebra API
+as well. The register layout is the same however.
+
+Fixed bug #1114: scan within set may use excessive CPU.
+
+Fixed memory leak that occurred in scan.
+
+Fixed memory leak that occurred for each deleted record.
+
+Optimize updates of records where content is almost identical to previous
+version of record. This makes updating of the internal explain database
+faster too.
+
+For RPN queries the index type (w,p,..) may be specified verbatim as
+structure attribute with string value, e.g. @attr 4=w .
+
+Changed record update API . It is now handled by function
+zebra_record_update which does insert/replace/delete/update of records .
+This function replaces zebra_record_{insert,delete} and
+zebra_admin_exchange_record. The DOM filter uses this feature and the
+@type attribute in record element specifies the action
+insert/replace/delete/update.
+
+Added support for multi-record updates (Bug #944). Based on patch from
+Hans-Werner Hilse.
+
+--- 2.0.12 2007/03/07
+
+Fixed bug with indexing of attributes for rec.grs-class of filters.
+If X-Path was enabled xelm a/@b would be ignored.
+
+Fixed bug in register system where 'no more space' messages was produced
+even though there was plenty of space.
+
+Fixed bug #884: Entity declarations in input are lost at retrieval time.
+
+Implemented new filter 'dom'. See test/xslt/dom-config*xml for examples.
+This, like alvis, performs indexing and retrieval using XSLT. But Unlike
+alvis, it allows multiple XSLT steps to be performed and does ISO2709
+reading. Bug #843.
+
+--- 2.0.10 2007/01/24
+
+Staticrank indexing is now an index register type defined in default.idx
+via directive 'staticrank'. The 'staticrank' directive for grs is no longer
+supported (was only implemented for Zebra 2.0.8).
+
+For searches, allow truncmax value to be controlled with attribute 13.
+If given, that overrides the value of 'truncmax'.
+
+For truncations being limited (abort at truncmax terms), zebrasrv returns
+SearchResponse with resultSetStatus=subset.
+
+For estimated hit counts, zebrasrv returns SearchResponse with
+resultSetStatus=estimate.
+
+--- 2.0.8 2007/01/15
+
+For searches, do not truncate more than at most 'truncmax' terms in one
+single term with right-truncation/regular attribute. By default, 'truncmax',
+is 10000.
+
+Bug #781: Easier tracking of result sets. We only do this when mkstemp
+is available (most moderun Unixes supports this). The PID is included
+in filename : tempdir/zrs_PID_XXXXXX.
+
+Added support for specification of staticrank for grs-class of filters.
+This is enabled by using 'staticrank indexname' in .abs. Contents of
+indexname (elm ... indexname:w) is then used as value for staticrank.
+
+Implemented sorting via the ISAMB system. To enable, use sortindex:i in
+zebra.cfg.
+
+Added special retrieval support for sort keys. These keys can also be
+fetched using zebra::index:field:s
+
+Added support for specification of approximative limits for whole query.
+This is specified as attribute type 12. Semantics is the same as
+estimatehits in zebra.cfg.
+
+--- 2.0.6 2006/11/28
+
+Fixed bug #736: Updates gets slower.
+
+Fixed bug #735: Delete fails to process rest of file after a record that
+does not exist,
+
+Added RPM package for Zebra 2.
+
+Improved indexing speed for large documents.
+
+Added support for special utility retrieval zebra:: which offers retrieval
+of fundamental properties for record, such as indexed terms, raw record,
+and system record ID.
+
+--- 2.0.4 2006/10/16
+
+Fixed bug #47: Commit needs to check for roll-back.
+
+Fixed bug #672: Trailing characters in password are ignored
+
+Added extra presence check for tcl.h, because some systems have
+tclConfig.sh installed even though Tcl C headers are missing.
+
+Optimized melm performance.
+
+Do not use sync(2) during commit (but rely on sync'd individual files).
+
+Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
+platforms the src argument was not updated. Problem was compiler
+optimization due to strict aliasing rules.
+
+--- 2.0.2 2006/09/22
+
+Bug fixes: #638, #647, #657, #669.
+
+Implement skip of 0 hit counts in scan. Useful for scan operations
+limited by a result set.
+
+Honor position attribute, i.e. allow first-in-field search. To
+enable this, "firstinfield 1" must be given for an index in
+default.idx. Enabled in tab/default.idx for w. At this stage
+first-in field is supported for phrase/and-list/or-list searches
+
+Common stream reader interface for record filters (struct ZebraRecStream).
+
+Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
+not depend properly on sub packages.
