71 Remove from js/pz2.js the code that translates just two diagnostic
72 codes (1 and 2) into human-readable messages. This is no longer
73 necessary at all, as PazPar2 has been returning the message as well as
74 the code in its responses since December 2012. Fixes PAZ-978.

118 Cache XML documents as they appear after normalization. The key
119 for the cache is database+record offset. Cache is removed if query

250 fired with filter before show from previous show completed.
252 Add 'date' handling for solr-pz2.xsl.
254 --- 1.6.33 2013/08/13
256 pz:authentication may carry user group password. If pz:authentication
257 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
258 authentication. Two forms are allowed
261 If no blanks are present, open authentication is in use (as before).
263 Fix {prev,next}recid elements that are returned by record
264 command. These were incorrect in versions 1.6.23 thru 1.6.32.

281 Local limit for fields of type "generic" (ie text fields) are
282 now normalized by mergekey rule before comparison takes place.
283 Before, no normalization took place and comparsion was, thus, exact.
285 New facility: dynamic rank , which allows ranking to be changed
286 for an existing result set. The rank can be set for search or
287 show. This overrides the rank for metadata elements (which fields
290 New facility:dynamic mergekey , which allows mergekey to be changed
291 for an existing result set. The mergekey can be set for search or
294 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
295 Also, allow ports to be given as names (not just integers).

300 Add MasterKey Connect configuration. Refer to section "non-standard
301 databases" for more information.
303 Allow timeformat for log to be specified with option -m (as Metaproxy
306 New Debian package pazpar2-dbg.
308 Fix NULL ptr reference of se->relevance. If a new search is initiated
309 and a CCL query fails to parse, Pazpar2 could crash.
311 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
312 existed in 1.6.29 only.
314 --- 1.6.29 2013/04/05
316 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
317 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
318 changed by setting "host" attribute for the "listen" element.
320 Change semantics of pz:extendrecs. Allow for repeated fetches .
321 pz:extendrecs is now the number of extra records to fetch (was total
324 --- 1.6.28 2013/03/21
326 Fix hang or memory violation if show occurred before a search. (not that
327 it makes much sense to perform a show before a search).

331 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
334 --- 1.6.26 2013/03/08
336 New pz:metadata attribute, empty="empty-value" for Pazpar2's
337 internal representation. With this attribute, Pazpar2 treates an empty
338 pz:metadata type as having the value for "empty" - if empty.
340 New setting, pz:extendrecs, which triggers extended fetch of records
341 for a database beyond pz:maxrecs for a show command.
343 Fix warning that was falsely issued for "missing limitmap".
345 Log message for Pazpart start/stop changed. Now using same style as
346 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
348 --- 1.6.25 2013/02/07
350 Fix hang of 2nd command=show with esn/syntax given.
352 --- 1.6.24 2013/01/18
354 New merge attribute type: 'first', which takes all metadata fields
355 from first target that returns the particular field.
357 --- 1.6.23 2013/01/02
359 Extend info command with hostname and YAZ SHA1
360 Indent results for both command stat and info.
362 Allow limit on merged content. The new configuration metadata
363 element, limitcluster, configures that a metadata element (name) be used
364 as limit name for search. Applies to the whole service (ie all targets),
365 unlike pz:limitmap which is configured per-target (database).
367 New feature: limitmap local:* matches against all metadata fields.
369 Allow repeated list in limitmap spec . Separated by comma. For
370 example: value="local:title,rpn:@attr 1=4".
372 New element <message> in bytarget response. Holds diagnostic message
373 of code (say 'Unsupported Use Attribute' for Bib-1 114).
375 Improved logging for record ingestion failures.
377 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
378 when YAZ is compiled without ICU support.
380 --- 1.6.22 2012/10/11
382 Requires YAZ-4.2.40 to support native solr support.
384 Fix and improve logic handling whether or not to re-do search on sort
385 order changes. A sort order with change in ascending/descending only
386 whould not trigger a new search, which is required for targets with
387 native sorting capabilities. Each client is now checked if instructions
388 (sortmap) exist for native sorting and only client that does requires
389 it is researched. Other clients is just re-ingesting the records,
390 they already have. The resultset is now cleared if any researching
393 Connection sharing between session has broken since version 1.6.8 with
394 introduction of logic that would minimize searching if pazpar2 could
395 detect this based on same query and limits and partly sort order.
396 This could lead to segementations violations.
398 Added a chapter in the manaul about relevance ranking.
400 --- 1.6.21 2012/09/24
402 Rank tweak: follow=number will increase mult by number if two terms
403 occur next to each other; number-1 if they are one term apart , .. 0
404 if they are number a part (all in order). Default is 0 (following
405 terms has no effect).
407 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
408 value given by lead and l is length from beginning of field where
409 term occurs (l=0 for first term, l=1 for second term, ..). Default
412 Rank tweak: length=strategy. length="linear" if mult is to be divided
413 by length (existing, default behavior), length="log" if mult is to be
414 divided by log2(1+length), length="none" if mult is not to be affected
417 --- 1.6.20 2012/09/21
419 Rank algorithm details may be printed as part of show response in
420 element <relevance_info>.. This is only printed if <rank debug="yes"/>
423 Record as returned by show/record command have a minimal indentation
424 which makes things human-readable.
426 New configuration of default sorting criteria (sort-default) in
427 service definition. If no criteria is defined it will be as before
430 Search command now supports sort parameter just as the show command.
431 If no parameter is give, it will use the service sort-default value.
433 --- 1.6.19 2012/09/18
435 Rank algorithm skips strings that gets normalized to empty string.
436 For example, & and ! could map to the empty string. The weight for
437 those terms is now 0 (as if they were not part of the query).
439 Rank algorithm does not use CCL from limitmap; only from the query
440 parameter (user query).
444 --- 1.6.18 2012/09/17
446 Rank algorithm configurable by 'rank' element inside service. So far
447 only, attribute 'cluster' is recognized. If cluster="yes", multiple
448 records inside a cluster boosts higher than single records. This
449 is default behavior and existing behavior. cluster="no" takes the
450 average score of each record in a cluster.
452 --- 1.6.17 2012/09/05
454 Fix bad re-use of connections (connections with changing proxy should not
457 --- 1.6.16 2012/08/22
459 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
460 resultset and sorting when the sort order is position. However this will be done on
461 every client poll, which will make pazpar2 continuing reset and fetching.
462 It should only be done on FIRST request where the sort order change.
464 Fix an issue on suggestion option: Also disable suggestions on empty string.
466 Clean up in turbo marc stylesheet.
468 Remove the hardcoded size of termlists.
470 --- 1.6.15 2012/06/27
472 New facility: ccldirective may be given in service definition. Allows
473 CCL parsing to be customized a bit, such as defining names of operators
476 New facility: raw record by checksum, rather than offset. The record
477 command optionally takes checksum which identifies certain record from
480 New facility: per field ranking. Rank may be given as M [F N] where
481 M is default rank and N is rank for CCL terms from field F.
483 --- 1.6.14 2012/06/04
485 Fix for IE7/8 in pz.js
487 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
489 Lower log level some places.
491 Remove some invalid test results.
493 --- 1.6.13 2012/05/23
495 Introducing a version=2 parameter for show, termlist and bytarget commands.
496 This enables pazpar2 to return approximation on hit and count count when
497 doing record filtering using the limit parameter on search and a
498 limitmap with a value of "local:"
500 Setting pz:xslt may embed local XSLT as an alternative to referring
502 Value is not CDATA but XML nodes embedded, so escaping is not necessary
503 but a root element *must* be present. For example:
504 <settings target="target="z3950.indexdata.com/marc">
513 Metadata field rank may given by XML internal document (pz:xslt
514 result). If rank is not given, the rank from service description is
517 Metadata field can now configured a default limitmap and facetmap.
518 Setting limitmap to "local:" would work for all kind of targets, but would
519 prob. not be the optimal solution. But at least better than the default behavior
520 of pazpar2 where no filtering is done.
522 A service definition can now also contains <set/> that defines service-wide
523 settings. These will override server-wide sets and will be overridded by
526 New setting, pz:present_chunk, that specifies number of records to fetch
527 at a time. Zero will disable chunkation; will fetch max_records at once.
529 --- 1.6.12 2012/03/14
531 Revert the format change in termlist response, that could break
532 some clients / UIs since they were expecting an (empty) element
533 if no facet values was found.
535 --- 1.6.11 2012/03/07
537 Revert the behavior of returning errors when unable to block
538 on termlist, bytarget and search, when unable to block due to
539 other block. The client will now receive a regular response,
540 but it will be logged in the server. A parameter (report) is
541 added to change behavior to return error response or WARNING
542 status message. Consider this "API" as private, as it is mostly
543 untested and could be changed in future releases.
545 Fix spell error in pz2.js fix in 1.6.10.
547 New Marc2TurboMarc.xsl (contribution from Sven Porst).
548 Can solve the missing marc21.xsl updates in some cases.
550 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
551 substring (contribtion from Sven Porst)
553 marc21.xsl: fix 1-based substring call
555 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
557 Add test_termlist_block to test suite
559 --- 1.6.10 2012/02/23
561 Fix SEGV for invalid PQFs and SRU/SOLR targets
562 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
564 Fix pz2.js: "null object" due to change in in bytarget result XML.
566 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
567 Added this normalization to the other subject-long fields (d6xx),
568 where it was missing.
570 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
571 Still differences around medium and holdings. marc21.xsl is not
572 longer active used by Index Data, and should be considered unsupported.
573 Use tmarc.xsl instead.
577 Fix SEGV that could occur for failed connections.
581 Fix bug for command sort that could return no results for active clients
582 (from previous search). This bug was present in 1.6.6-1.6.7.
584 Fix bug in results that could include results that should have been
585 filtered out. This bug was present in 1.6.6-1.6.7.
589 Fix bug introduced in 1.6.6 where a connection re-use could stall
592 Local filtering may now specify a local metadata field, eg.
593 pz:limitmap:somefield[t]=local:otherfield
597 For search, when limit and or filtering is in place and search
598 is identical to previous search, the result set is re-used and the
599 target is not searched.
601 Limits may work perform local filtering as well, by using "local:"
606 Updated bytarget command to contain a suggestions element with misspelled
607 words and suggestions to these. pz2.js has been updated to deliver this
608 onwards as well. Only target that currently delivers this is the solr
609 client in YAZ 4.2.18.
613 New service definition element, xslt, that allows an embedded stylesheet
614 to be defined. This can be referred to from pz:xslt as an alternative to
617 New pz:sortmap:field setting for specifying hints on how to make
618 a target natively sort on a field. This is used for command=show in
619 conjunction with sort.
621 New pz:url setting for specifying the actual URL for a target. When
622 this is used the target ID is not used as URL anymore and the target ID
623 may be almost any string (not including []).
625 command=termlist without name parameter returns all termlists/facets.
626 Previously if name parameter was omitted, only "subject" was returned.
630 Make termlist sorting stable. Terms with same frequency are now sorted by
631 their display name. This makes a pretty display and improves our
632 regression test because qsort is not a stable sort.
634 New sort parameter value 'position'. The 'position' sorts merged records
635 by their original position from the remote target. This is primarily useful
636 for debugging and may be used for targets that already perform some kind
637 of relevance ranking. Note that sort by default is decreasing; so to get
638 records in their original order sort=position:1 must be used.
642 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
644 Facility to change working directory for pazpar2 daemon. Option -wdir
645 sets working directory to dir. This facility is useful if core dumps
646 must be saved. In this case, the current working directory must be
647 writable by the running user, such as "nobody".
651 New configuration element <icu_chain> for <server>/<service> which
652 allows a named ICU rule (chain) to be defined. The names relevance,
653 sort, mergekey and facet are used for those operations. The definition
654 <icu_chain id="sort" locale="en"> .. </icu_chain>
656 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
657 And so on.. for relevance, mergekey and facet as well. The latter
658 style is deprecated. The facet terms are normalized by the facet
659 rule by default. This may be changed on a metadata field basis by
660 defining the new attribute 'facetrule' for the metadata element.
662 <icu_chain id="myrule" locale="en"> ... </icu_chain>
663 <metadata name="author" termlist="yes" facetrule="myrule"/>
665 Preserve rorder for merged metadata. Fixes issue as reported by Sven
666 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
668 tmarc.xsl: set journal-subpart to 773$ only.
672 Modify the behavior for the limit parameter (first defined in 1.5.7).
673 Mapping of limit searches are now defined by the new configuration item
674 pz:limitmap. Fix a dead-lock problem with the limit parameter.
676 Extend tmarc.xsl to extract 773$g data (OpenURL).
680 ICU default maps remove backquote (`).
682 Command 'search' takes limit parameter (optional). The limit parameter
683 allows a search to be limited one or more facets and the corresponding
684 values. This is for server side filtering.
686 Configure tweak: Use -lm for log(3) if needed
690 Fix a problem with skiparticle sortkey that could be completely
691 ignored (and reduced to "").
693 Fix dependency problem in pazpar2 RPM package (did not require
694 libyaz4 as it should).
698 Fix memory leak that occurred for command=termlist&name=xtargets .
700 Pazpar2 may save HTTP requests. Enabled by option -R.
704 Experimental support for DTIC DADS target. New dads-pz2.xsl.
706 Support for query_syntax (overrides the default for SRU | Z39.50)
708 Support for extraArgs (ZOOM "extraArgs" option) for targets
710 New commands: status-server and status-session
714 Fix for threaded runs: Client now have a copy of the database URL,
715 which can used after the database has been release from the client.
716 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
718 tmarc.xsl: Add journal-title-abbrev and full text.
720 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
722 Fix for cmd=record before search.
724 Session Logging clean up.
726 Fix wrong termlist factor when maxrecs is different from 100.
730 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
731 Term factor is default enabled but can be diseabled by
732 pz:termlist_term_factor=0
736 Add scaling of facet count. Currently always enabled, needs fixing.
737 Allow user-defined info for target suffix. This has no meaning in
738 Pazpar2 except to distinguish targets from each other. The suffix
739 data begins with #. For example z3950.indexdata.com/gils#Mydata
741 Added exact-match recordfilter; format name=value
745 SOLR support. Pazpar2 may operate as web service client for SOLR.
749 Fix for show command and block=1 (dead lock). Bug was introduced in
754 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
755 tested on CentOS 5.5 only.
759 Fix problem with result sets being removed from a client session
760 if the connection for it was resused by another session. Bug #3489.
762 New iphone UI for Pazpar2 (www/iphone).
766 Fixes for threaded operation.
768 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
770 New example services in etc/services in source. In the Debian packages
771 these are located in /etc/pazpar2/services-available
773 Threaded mode operational on Windows. Requires Windows 7 or Windows
776 Default value of setting pz:max_connections is 0 which means that there
777 is no limit on number of connections.
781 Pazpar2 may operate in threaded mode. Enabled by element threads in
782 the configuration. See pazpar2_conf for details.
784 New setting setting: pz:max_connections. Setting pz:max_connections is
785 a limit of number of sockets to a host. When this limit is reached,
786 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
787 The client will be marked Client_Error when it can not be searched
788 (other clients in a session may work). If pz:max_connections is not set
789 for a target, a value of 30 will be used. Note: the pz:max_connections
790 will only work in threaded mode.
792 pz2.js: JSON support for show.
794 Debian package: Enable default service, default.xml, before starting
795 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
799 Debian version depends on on libyaz4. Note that Pazpar2 will still
800 compile from source with YAZ 3.
802 Split services into separate files. The example configuration file
803 pazpar2.cfg.dist now includes a default service default.xml (part of
804 etc). And default.xml includes settings/edu.xml. The default.xml file,
805 not to be confused with settings/defaults.xml, is a template for jsdemo
806 and other services. The Debian package installs /etc/pazpar2/server.xml
807 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
808 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
809 The default.xml (from etc) is installed in /etc/pazpar2/services-available
810 and a symlink to it is created from services-enabled. The default.xml
811 service is unnamed and, thus, will be used by jsdemo and test1.
813 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
814 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
818 Support for additional fields in cf.xsl and pazpar2.conf.dist:
819 publisher, available, due, location (=locallocation), callno
820 (=callnumber), thumburl and score.
822 Describe pz:xslt and the auto setting.
824 Move mergekey definition away from the normalization stylesheets and
825 define a mergekey common for all target types in pazpar2.cfg.
827 Code update: Use the Odr_int type for hit counts. This is part of
828 YAZ 3.0.47 and later and so configure checks for that.
832 Metadata attribute 'skiparticle' also works for ICU based
833 normalization. (was only working for the non-ICU/ASCII before).
835 Command bytarget with argument settings=1 will show settings per
836 target.. This is to be able to verify correct settings and be able to
837 test that they are correct. The database settings array size is now
838 also stored.. Problems with database settings array is that if not
839 careful it will be too small (smaller than dictionary per-service
842 Make record list sorting stable by comparing mergekey for records if
843 relevance/title or other sorting criteria all match. This is merely to
844 ensure that our regressions tests works (reproducible output).
846 Relevance calculation changes: use a different denominator (length) for
847 per-field relevance scoring.. Instead of length of all ranked fields we
848 now use length of individual fields (as if they were individual "free"
849 text fields). This will ensure that documents with a long field with no
850 match (say description) will not "hurt" a title match.
852 Diagnostic member was not set on connection error. Fixed
856 Command search takes two optional parameters, startecs and maxrecs,
857 that specifies the start offset (0, 1, ...) and maximum number of records
858 to fetch for each target.
860 XSLTs + MARC maps are cached within a session so we don't re-parse
861 them over and over again. Even for a session with a single search
862 there's much to be gained because many targets use the same
865 The metadata attribute 'mergekey' now takes one of three values 'no',
866 'required', 'optional' . And the resulting mergekey from metadata
867 is now ordered in the same way as metadata in the service definition.
868 Older Pazpar2 version use the order in which metadata appeared in a
871 The search argument 'filter' now offers a new operator ~ which does a
872 substring match. The = operator works as before: string match for
873 anything but pz:id, or target match for pz:id.
875 New setting pz:recordfilter. The value of this setting takes the
876 form name[~value]. This setting makes Pazpar2 ignore all retrieved
877 records that do not have the metadata element name with value substring
880 Pazpar2 allows YAZ log level to be set (option -v).
884 For WS responses Pazpar2 creates XML header. Exception: raw record.
886 Setting XML files are now stored in etc/settings instead of etc. This
887 reflects the layout with the Debian package layout.
889 Settings may be posted for command=settings. The POSTed settings must
890 have root element 'settings' like regular setting files. In order to be
891 recognized, the POST request must use Content-Type=text/xml.
893 A service may be posted for command=init. This service will be used
894 during the session. The service may have its own target settings,
895 ICU config, timeout, etc. In order to be recognized, the POST request
896 must use Content-Type=text/xml.
898 Timeout values may be given per-service. That's element 'timeout'
899 which takes three attribute values (a subset may be given): 'session',
900 'z3950_operation', 'z3950_session'. Option -T is no longer supported
901 - used to specify session timeout.
903 Option -t tests the Pazpar2 configuration and returns exit code
904 (0=success, non-zero=failure). In previous version of Pazpar2, -t
905 specified local settings.
907 In version 1.2.0 the configuration file - after include processing -
908 was dumped to stdout. Now, the configuration is only dumped to the
909 yaz log file if option -d is given.
913 Configuration may now have multiple server areas. This means that a
914 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
915 yet supported - on a server basis. Configuration may also have multiple
916 services .. That is repeating service elements inside a server. Each
917 has an attribute 'id' which serves as service ID. This ID in turn may
918 be used in a Pazpar2 session, by specifying parameter service=ID for
919 command init. There can be at most one unnamed service inside a server
920 which can be referred to by not specifying an service ID for command
921 init (backwards compatible). In order to partition multiple servers and
922 services a new include directive has been added. This takes an attribute
923 'src' which specifies one or more sub-files. For example to include
924 service files, one might use:
925 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
926 It is the intention that that completely makes the settings directive
929 Fix problem where the record command would wait forever if there were
930 no targets to wait for (activeclients == 0).
934 One result set is created per session (last search) rather than for
935 each connection which happen to be shared (bug #3009).
937 marc21 stylesheets changed for efficiency.
941 Session timeout may be specified on the command-line as option -T.
943 Pazpar2 may now be operated in a no-merged mode for records.. All records
944 will be considered unique. This mode is enabled if no mergekey is
945 generated by the normalization stylesheet (pz:xslt).
947 Pazpar2 caches original records from each target and the 'record' command
948 with offset returns the original record if 'syntax' and 'esn' are NOT
949 specified. This speeds up retrieval of original records but also means
950 that Pazpar2 uses more memory. The cached records will be freed when the
951 session terminates or a new search is executed.
953 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
954 library part of YAZ is used.
956 Added SRU client support.
958 Automatically computes pz:nativesyntax if not provided. Works for XML and
961 --- 1.0.13 2008/11/24

971 Fixed check for application/x-www-form-urlencoded parameters.
973 --- 1.0.10 2008/10/14
975 Fixes for IE in pz2.js.
977 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
981 Changed the JS library pz2.js to use POST for long URL (+ params).
983 Added installation instructions for Windows. Note: NT services is
984 NOT available until we make a new release of YAZ.
986 Preserve order of repeated metadata fields (they were reversed before).
988 More MARC21 information extracted for metadata.
992 Fixed bug #1162: HTML entities are not escaped properly.
994 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
998 Marc21 stylesheet updated to reflect multiple full text fields
1000 --- 1.0.6 2008/03/12
1002 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1004 Fixed bug 2100: Database wildcards not working
1006 --- 1.0.5 2007/11/09
1008 Added support for retrieval of records in binary.
1010 Fixed bug 1794: Pazpar2 does not return valid XML.
1012 Deal with ICU not returning sortkey (resulted in SEGV before).
1014 --- 1.0.4 2007/09/28
1016 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1017 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1019 Improved diagnostics when Pazpar2 HTTP decoding fails.
1021 Pazpar2 requests may be POSTed as using Content-Type
1022 application/x-www-form-urlencoded.
1024 Pazpar2 honors LF in HTTP headers.
1026 Handle targets that handle negative hit counts (should not happen, but it
1029 --- 1.0.3 2007/09/19
1031 ICU is used for tokenization and normalization of the following: mergekey,
1032 sorting, relevance terms.
1034 Debian package now enables ICU tokenization and normalization by default.
1036 --- 1.0.2 2007/08/22
1038 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1039 ways: Either as parameters to the normalization stylesheets (which would allow the
1040 programmer to postprocess or use the values in any way) or after the normalization
1041 step, in which case values are made part of the normalized record (and available for
1042 sorting, termlists, display, or other interface-related use.
1044 Implemented sorting by year.
1046 Option -d dumps records to the current log file instead of stderr.
1048 Fixes for compilation on cygwin.
1050 Z39.50 client code uses pz:elements. pz:elements was recognized in
1051 earlier Pazpar2 versions but it was not used for anything.
1053 icu_chain_test is using fgets instead of getline - fixes compilation
1056 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1057 query conversions fail (rather than _any_). This means targets that do
1058 not support some fields are ignored in a search.
1060 --- 1.0.1 2007/07/03
1062 Improved handling of socket timeout for Z39.50 connections.
1064 Misc documentation updates and spell fixes.
1066 Debian package pazpar2 creates log rotate entry.
