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

205 Dump main configuration file during start of Pazpar2 PAZ-957
209 Log ingest failures and record failures:
211 Clean up logging PAZ-942
212 Use session lead in more places. Log hits/records/filtered for each
213 target when fetching is complete. Log hit count when a search
214 (response) is received. Remove some less useful log messages.
216 Fix warning about about missing (internal) stylesheet PAZ-956
218 Report number of filtered records in bytarget PAZ-954
220 Cache XML documents as they appear after normalization. The key
221 for the cache is database+record offset. Cache is removed if query
222 is modified for search. This speeds up re-establishing a result set
223 for databases where new query is same previous query.

283 Doc: fix misplaced variablelist tag.
285 --- 1.6.39 2014/02/19
287 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
288 It's been like that since version 1.1.1 from August 2009.
290 Add support for result-set caching via memcached. See description of
291 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.

347 Strip #-suffix for ZOOM URLs. PAZ-892
349 --- 1.6.34 2013/08/30
351 Fix issue with hanging show/bytarget. Could happen if new search was
352 fired with filter before show from previous show completed.
354 Add 'date' handling for solr-pz2.xsl.
356 --- 1.6.33 2013/08/13
358 pz:authentication may carry user group password. If pz:authentication
359 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
360 authentication. Two forms are allowed
363 If no blanks are present, open authentication is in use (as before).
365 Fix {prev,next}recid elements that are returned by record
366 command. These were incorrect in versions 1.6.23 thru 1.6.32.
368 --- 1.6.32 2013/06/14
370 Experimental support for snippets. If argument snippets=1 is given
371 for command record or show, the text will include <match>-tags for
372 those area that matches.
374 Fix memory leak WRT client structures (incorrect inc ref count).
376 Log when a HTTP response is serialized and the time elapsed.
378 New command, service, which returns current service XML in use for
381 --- 1.6.31 2013/05/24
383 Local limit for fields of type "generic" (ie text fields) are
384 now normalized by mergekey rule before comparison takes place.
385 Before, no normalization took place and comparsion was, thus, exact.
387 New facility: dynamic rank , which allows ranking to be changed
388 for an existing result set. The rank can be set for search or
389 show. This overrides the rank for metadata elements (which fields
392 New facility:dynamic mergekey , which allows mergekey to be changed
393 for an existing result set. The mergekey can be set for search or
396 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
397 Also, allow ports to be given as names (not just integers).
398 Fix @-notation on systems that don't support IPV6 sockets.
400 --- 1.6.30 2013/04/26
402 Add MasterKey Connect configuration. Refer to section "non-standard
403 databases" for more information.
405 Allow timeformat for log to be specified with option -m (as Metaproxy
408 New Debian package pazpar2-dbg.
410 Fix NULL ptr reference of se->relevance. If a new search is initiated
411 and a CCL query fails to parse, Pazpar2 could crash.
413 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
414 existed in 1.6.29 only.
416 --- 1.6.29 2013/04/05
418 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
419 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
420 changed by setting "host" attribute for the "listen" element.
422 Change semantics of pz:extendrecs. Allow for repeated fetches .
423 pz:extendrecs is now the number of extra records to fetch (was total
426 --- 1.6.28 2013/03/21
428 Fix hang or memory violation if show occurred before a search. (not that
429 it makes much sense to perform a show before a search).
431 --- 1.6.27 2013/03/08
433 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
436 --- 1.6.26 2013/03/08
438 New pz:metadata attribute, empty="empty-value" for Pazpar2's
439 internal representation. With this attribute, Pazpar2 treates an empty
440 pz:metadata type as having the value for "empty" - if empty.
442 New setting, pz:extendrecs, which triggers extended fetch of records
443 for a database beyond pz:maxrecs for a show command.
445 Fix warning that was falsely issued for "missing limitmap".
447 Log message for Pazpart start/stop changed. Now using same style as
448 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
450 --- 1.6.25 2013/02/07
452 Fix hang of 2nd command=show with esn/syntax given.
454 --- 1.6.24 2013/01/18
456 New merge attribute type: 'first', which takes all metadata fields
457 from first target that returns the particular field.
459 --- 1.6.23 2013/01/02
461 Extend info command with hostname and YAZ SHA1
462 Indent results for both command stat and info.
464 Allow limit on merged content. The new configuration metadata
465 element, limitcluster, configures that a metadata element (name) be used
466 as limit name for search. Applies to the whole service (ie all targets),
467 unlike pz:limitmap which is configured per-target (database).
469 New feature: limitmap local:* matches against all metadata fields.
471 Allow repeated list in limitmap spec . Separated by comma. For
472 example: value="local:title,rpn:@attr 1=4".
474 New element <message> in bytarget response. Holds diagnostic message
475 of code (say 'Unsupported Use Attribute' for Bib-1 114).
477 Improved logging for record ingestion failures.
479 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
480 when YAZ is compiled without ICU support.
482 --- 1.6.22 2012/10/11
484 Requires YAZ-4.2.40 to support native solr support.
486 Fix and improve logic handling whether or not to re-do search on sort
487 order changes. A sort order with change in ascending/descending only
488 whould not trigger a new search, which is required for targets with
489 native sorting capabilities. Each client is now checked if instructions
490 (sortmap) exist for native sorting and only client that does requires
491 it is researched. Other clients is just re-ingesting the records,
492 they already have. The resultset is now cleared if any researching
495 Connection sharing between session has broken since version 1.6.8 with
496 introduction of logic that would minimize searching if pazpar2 could
497 detect this based on same query and limits and partly sort order.
498 This could lead to segementations violations.
500 Added a chapter in the manaul about relevance ranking.
502 --- 1.6.21 2012/09/24
504 Rank tweak: follow=number will increase mult by number if two terms
505 occur next to each other; number-1 if they are one term apart , .. 0
506 if they are number a part (all in order). Default is 0 (following
507 terms has no effect).
509 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
510 value given by lead and l is length from beginning of field where
511 term occurs (l=0 for first term, l=1 for second term, ..). Default
514 Rank tweak: length=strategy. length="linear" if mult is to be divided
515 by length (existing, default behavior), length="log" if mult is to be
516 divided by log2(1+length), length="none" if mult is not to be affected
519 --- 1.6.20 2012/09/21
521 Rank algorithm details may be printed as part of show response in
522 element <relevance_info>.. This is only printed if <rank debug="yes"/>
525 Record as returned by show/record command have a minimal indentation
526 which makes things human-readable.
528 New configuration of default sorting criteria (sort-default) in
529 service definition. If no criteria is defined it will be as before
532 Search command now supports sort parameter just as the show command.
533 If no parameter is give, it will use the service sort-default value.
535 --- 1.6.19 2012/09/18
537 Rank algorithm skips strings that gets normalized to empty string.
538 For example, & and ! could map to the empty string. The weight for
539 those terms is now 0 (as if they were not part of the query).
541 Rank algorithm does not use CCL from limitmap; only from the query
542 parameter (user query).
546 --- 1.6.18 2012/09/17
548 Rank algorithm configurable by 'rank' element inside service. So far
549 only, attribute 'cluster' is recognized. If cluster="yes", multiple
550 records inside a cluster boosts higher than single records. This
551 is default behavior and existing behavior. cluster="no" takes the
552 average score of each record in a cluster.
554 --- 1.6.17 2012/09/05
556 Fix bad re-use of connections (connections with changing proxy should not
559 --- 1.6.16 2012/08/22
561 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
562 resultset and sorting when the sort order is position. However this will be done on
563 every client poll, which will make pazpar2 continuing reset and fetching.
564 It should only be done on FIRST request where the sort order change.
566 Fix an issue on suggestion option: Also disable suggestions on empty string.
568 Clean up in turbo marc stylesheet.
570 Remove the hardcoded size of termlists.
572 --- 1.6.15 2012/06/27
574 New facility: ccldirective may be given in service definition. Allows
575 CCL parsing to be customized a bit, such as defining names of operators
578 New facility: raw record by checksum, rather than offset. The record
579 command optionally takes checksum which identifies certain record from
582 New facility: per field ranking. Rank may be given as M [F N] where
583 M is default rank and N is rank for CCL terms from field F.
585 --- 1.6.14 2012/06/04
587 Fix for IE7/8 in pz.js
589 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
591 Lower log level some places.
593 Remove some invalid test results.
595 --- 1.6.13 2012/05/23
597 Introducing a version=2 parameter for show, termlist and bytarget commands.
598 This enables pazpar2 to return approximation on hit and count count when
599 doing record filtering using the limit parameter on search and a
600 limitmap with a value of "local:"
602 Setting pz:xslt may embed local XSLT as an alternative to referring
604 Value is not CDATA but XML nodes embedded, so escaping is not necessary
605 but a root element *must* be present. For example:
606 <settings target="target="z3950.indexdata.com/marc">
615 Metadata field rank may given by XML internal document (pz:xslt
616 result). If rank is not given, the rank from service description is
619 Metadata field can now configured a default limitmap and facetmap.
620 Setting limitmap to "local:" would work for all kind of targets, but would
621 prob. not be the optimal solution. But at least better than the default behavior
622 of pazpar2 where no filtering is done.
624 A service definition can now also contains <set/> that defines service-wide
625 settings. These will override server-wide sets and will be overridded by
628 New setting, pz:present_chunk, that specifies number of records to fetch
629 at a time. Zero will disable chunkation; will fetch max_records at once.
631 --- 1.6.12 2012/03/14
633 Revert the format change in termlist response, that could break
634 some clients / UIs since they were expecting an (empty) element
635 if no facet values was found.
637 --- 1.6.11 2012/03/07
639 Revert the behavior of returning errors when unable to block
640 on termlist, bytarget and search, when unable to block due to
641 other block. The client will now receive a regular response,
642 but it will be logged in the server. A parameter (report) is
643 added to change behavior to return error response or WARNING
644 status message. Consider this "API" as private, as it is mostly
645 untested and could be changed in future releases.
647 Fix spell error in pz2.js fix in 1.6.10.
649 New Marc2TurboMarc.xsl (contribution from Sven Porst).
650 Can solve the missing marc21.xsl updates in some cases.
652 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
653 substring (contribtion from Sven Porst)
655 marc21.xsl: fix 1-based substring call
657 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
659 Add test_termlist_block to test suite
661 --- 1.6.10 2012/02/23
663 Fix SEGV for invalid PQFs and SRU/SOLR targets
664 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
666 Fix pz2.js: "null object" due to change in in bytarget result XML.
668 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
669 Added this normalization to the other subject-long fields (d6xx),
670 where it was missing.
672 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
673 Still differences around medium and holdings. marc21.xsl is not
674 longer active used by Index Data, and should be considered unsupported.
675 Use tmarc.xsl instead.
679 Fix SEGV that could occur for failed connections.
683 Fix bug for command sort that could return no results for active clients
684 (from previous search). This bug was present in 1.6.6-1.6.7.
686 Fix bug in results that could include results that should have been
687 filtered out. This bug was present in 1.6.6-1.6.7.
691 Fix bug introduced in 1.6.6 where a connection re-use could stall
694 Local filtering may now specify a local metadata field, eg.
695 pz:limitmap:somefield[t]=local:otherfield
699 For search, when limit and or filtering is in place and search
700 is identical to previous search, the result set is re-used and the
701 target is not searched.
703 Limits may work perform local filtering as well, by using "local:"
708 Updated bytarget command to contain a suggestions element with misspelled
709 words and suggestions to these. pz2.js has been updated to deliver this
710 onwards as well. Only target that currently delivers this is the solr
711 client in YAZ 4.2.18.
715 New service definition element, xslt, that allows an embedded stylesheet
716 to be defined. This can be referred to from pz:xslt as an alternative to
719 New pz:sortmap:field setting for specifying hints on how to make
720 a target natively sort on a field. This is used for command=show in
721 conjunction with sort.
723 New pz:url setting for specifying the actual URL for a target. When
724 this is used the target ID is not used as URL anymore and the target ID
725 may be almost any string (not including []).
727 command=termlist without name parameter returns all termlists/facets.
728 Previously if name parameter was omitted, only "subject" was returned.
732 Make termlist sorting stable. Terms with same frequency are now sorted by
733 their display name. This makes a pretty display and improves our
734 regression test because qsort is not a stable sort.
736 New sort parameter value 'position'. The 'position' sorts merged records
737 by their original position from the remote target. This is primarily useful
738 for debugging and may be used for targets that already perform some kind
739 of relevance ranking. Note that sort by default is decreasing; so to get
740 records in their original order sort=position:1 must be used.
744 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
746 Facility to change working directory for pazpar2 daemon. Option -wdir
747 sets working directory to dir. This facility is useful if core dumps
748 must be saved. In this case, the current working directory must be
749 writable by the running user, such as "nobody".
753 New configuration element <icu_chain> for <server>/<service> which
754 allows a named ICU rule (chain) to be defined. The names relevance,
755 sort, mergekey and facet are used for those operations. The definition
756 <icu_chain id="sort" locale="en"> .. </icu_chain>
758 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
759 And so on.. for relevance, mergekey and facet as well. The latter
760 style is deprecated. The facet terms are normalized by the facet
761 rule by default. This may be changed on a metadata field basis by
762 defining the new attribute 'facetrule' for the metadata element.
764 <icu_chain id="myrule" locale="en"> ... </icu_chain>
765 <metadata name="author" termlist="yes" facetrule="myrule"/>
767 Preserve rorder for merged metadata. Fixes issue as reported by Sven
768 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
770 tmarc.xsl: set journal-subpart to 773$ only.
774 Modify the behavior for the limit parameter (first defined in 1.5.7).
775 Mapping of limit searches are now defined by the new configuration item
776 pz:limitmap. Fix a dead-lock problem with the limit parameter.
778 Extend tmarc.xsl to extract 773$g data (OpenURL).
782 ICU default maps remove backquote (`).
784 Command 'search' takes limit parameter (optional). The limit parameter
785 allows a search to be limited one or more facets and the corresponding
786 values. This is for server side filtering.
788 Configure tweak: Use -lm for log(3) if needed
792 Fix a problem with skiparticle sortkey that could be completely
793 ignored (and reduced to "").
795 Fix dependency problem in pazpar2 RPM package (did not require
796 libyaz4 as it should).
800 Fix memory leak that occurred for command=termlist&name=xtargets .
802 Pazpar2 may save HTTP requests. Enabled by option -R.
806 Experimental support for DTIC DADS target. New dads-pz2.xsl.
808 Support for query_syntax (overrides the default for SRU | Z39.50)
810 Support for extraArgs (ZOOM "extraArgs" option) for targets
812 New commands: status-server and status-session
816 Fix for threaded runs: Client now have a copy of the database URL,
817 which can used after the database has been release from the client.
818 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
820 tmarc.xsl: Add journal-title-abbrev and full text.
822 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
824 Fix for cmd=record before search.
826 Session Logging clean up.
828 Fix wrong termlist factor when maxrecs is different from 100.
832 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
833 Term factor is default enabled but can be diseabled by
834 pz:termlist_term_factor=0
838 Add scaling of facet count. Currently always enabled, needs fixing.
839 Allow user-defined info for target suffix. This has no meaning in
840 Pazpar2 except to distinguish targets from each other. The suffix
841 data begins with #. For example z3950.indexdata.com/gils#Mydata
843 Added exact-match recordfilter; format name=value
847 SOLR support. Pazpar2 may operate as web service client for SOLR.
851 Fix for show command and block=1 (dead lock). Bug was introduced in
856 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
857 tested on CentOS 5.5 only.
861 Fix problem with result sets being removed from a client session
862 if the connection for it was resused by another session. Bug #3489.
864 New iphone UI for Pazpar2 (www/iphone).
868 Fixes for threaded operation.
870 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
872 New example services in etc/services in source. In the Debian packages
873 these are located in /etc/pazpar2/services-available
875 Threaded mode operational on Windows. Requires Windows 7 or Windows
878 Default value of setting pz:max_connections is 0 which means that there
879 is no limit on number of connections.
883 Pazpar2 may operate in threaded mode. Enabled by element threads in
884 the configuration. See pazpar2_conf for details.
886 New setting setting: pz:max_connections. Setting pz:max_connections is
887 a limit of number of sockets to a host. When this limit is reached,
888 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
889 The client will be marked Client_Error when it can not be searched
890 (other clients in a session may work). If pz:max_connections is not set
891 for a target, a value of 30 will be used. Note: the pz:max_connections
892 will only work in threaded mode.
894 pz2.js: JSON support for show.
896 Debian package: Enable default service, default.xml, before starting
897 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
901 Debian version depends on on libyaz4. Note that Pazpar2 will still
902 compile from source with YAZ 3.
904 Split services into separate files. The example configuration file
905 pazpar2.cfg.dist now includes a default service default.xml (part of
906 etc). And default.xml includes settings/edu.xml. The default.xml file,
907 not to be confused with settings/defaults.xml, is a template for jsdemo
908 and other services. The Debian package installs /etc/pazpar2/server.xml
909 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
910 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
911 The default.xml (from etc) is installed in /etc/pazpar2/services-available
912 and a symlink to it is created from services-enabled. The default.xml
913 service is unnamed and, thus, will be used by jsdemo and test1.
915 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
916 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
920 Support for additional fields in cf.xsl and pazpar2.conf.dist:
921 publisher, available, due, location (=locallocation), callno
922 (=callnumber), thumburl and score.
924 Describe pz:xslt and the auto setting.
926 Move mergekey definition away from the normalization stylesheets and
927 define a mergekey common for all target types in pazpar2.cfg.
929 Code update: Use the Odr_int type for hit counts. This is part of
930 YAZ 3.0.47 and later and so configure checks for that.
934 Metadata attribute 'skiparticle' also works for ICU based
935 normalization. (was only working for the non-ICU/ASCII before).
937 Command bytarget with argument settings=1 will show settings per
938 target.. This is to be able to verify correct settings and be able to
939 test that they are correct. The database settings array size is now
940 also stored.. Problems with database settings array is that if not
941 careful it will be too small (smaller than dictionary per-service
944 Make record list sorting stable by comparing mergekey for records if
945 relevance/title or other sorting criteria all match. This is merely to
946 ensure that our regressions tests works (reproducible output).
948 Relevance calculation changes: use a different denominator (length) for
949 per-field relevance scoring.. Instead of length of all ranked fields we
950 now use length of individual fields (as if they were individual "free"
951 text fields). This will ensure that documents with a long field with no
952 match (say description) will not "hurt" a title match.
954 Diagnostic member was not set on connection error. Fixed
958 Command search takes two optional parameters, startecs and maxrecs,
959 that specifies the start offset (0, 1, ...) and maximum number of records
960 to fetch for each target.
962 XSLTs + MARC maps are cached within a session so we don't re-parse
963 them over and over again. Even for a session with a single search
964 there's much to be gained because many targets use the same
967 The metadata attribute 'mergekey' now takes one of three values 'no',
968 'required', 'optional' . And the resulting mergekey from metadata
969 is now ordered in the same way as metadata in the service definition.
970 Older Pazpar2 version use the order in which metadata appeared in a
973 The search argument 'filter' now offers a new operator ~ which does a
974 substring match. The = operator works as before: string match for
975 anything but pz:id, or target match for pz:id.
977 New setting pz:recordfilter. The value of this setting takes the
978 form name[~value]. This setting makes Pazpar2 ignore all retrieved
979 records that do not have the metadata element name with value substring
982 Pazpar2 allows YAZ log level to be set (option -v).
986 For WS responses Pazpar2 creates XML header. Exception: raw record.
988 Setting XML files are now stored in etc/settings instead of etc. This
989 reflects the layout with the Debian package layout.
991 Settings may be posted for command=settings. The POSTed settings must
992 have root element 'settings' like regular setting files. In order to be
993 recognized, the POST request must use Content-Type=text/xml.
995 A service may be posted for command=init. This service will be used
996 during the session. The service may have its own target settings,
997 ICU config, timeout, etc. In order to be recognized, the POST request
998 must use Content-Type=text/xml.
1000 Timeout values may be given per-service. That's element 'timeout'
1001 which takes three attribute values (a subset may be given): 'session',
1002 'z3950_operation', 'z3950_session'. Option -T is no longer supported
1003 - used to specify session timeout.
1005 Option -t tests the Pazpar2 configuration and returns exit code
1006 (0=success, non-zero=failure). In previous version of Pazpar2, -t
1007 specified local settings.
1009 In version 1.2.0 the configuration file - after include processing -
1010 was dumped to stdout. Now, the configuration is only dumped to the
1011 yaz log file if option -d is given.
1013 --- 1.2.0 2009/09/10
1015 Configuration may now have multiple server areas. This means that a
1016 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
1017 yet supported - on a server basis. Configuration may also have multiple
1018 services .. That is repeating service elements inside a server. Each
1019 has an attribute 'id' which serves as service ID. This ID in turn may
1020 be used in a Pazpar2 session, by specifying parameter service=ID for
1021 command init. There can be at most one unnamed service inside a server
1022 which can be referred to by not specifying an service ID for command
1023 init (backwards compatible). In order to partition multiple servers and
1024 services a new include directive has been added. This takes an attribute
1025 'src' which specifies one or more sub-files. For example to include
1026 service files, one might use:
1027 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
1028 It is the intention that that completely makes the settings directive
1031 Fix problem where the record command would wait forever if there were
1032 no targets to wait for (activeclients == 0).
1034 --- 1.1.1 2009/08/28
1036 One result set is created per session (last search) rather than for
1037 each connection which happen to be shared (bug #3009).
1039 marc21 stylesheets changed for efficiency.
1041 --- 1.1.0 2009/08/19
1043 Session timeout may be specified on the command-line as option -T.
1045 Pazpar2 may now be operated in a no-merged mode for records.. All records
1046 will be considered unique. This mode is enabled if no mergekey is
1047 generated by the normalization stylesheet (pz:xslt).
1049 Pazpar2 caches original records from each target and the 'record' command
1050 with offset returns the original record if 'syntax' and 'esn' are NOT
1051 specified. This speeds up retrieval of original records but also means
1052 that Pazpar2 uses more memory. The cached records will be freed when the
1053 session terminates or a new search is executed.
1055 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
1056 library part of YAZ is used.
1058 Added SRU client support.
1060 Automatically computes pz:nativesyntax if not provided. Works for XML and
1063 --- 1.0.13 2008/11/24
1065 Command bytarget returns name of target (if defined).
1067 --- 1.0.12 2008/11/04
1069 Fixed bug #2021.. location now holds all brief elements.
1071 --- 1.0.11 2008/10/15
1073 Fixed check for application/x-www-form-urlencoded parameters.
1075 --- 1.0.10 2008/10/14
1077 Fixes for IE in pz2.js.
1079 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
1081 --- 1.0.9 2008/05/23
1083 Changed the JS library pz2.js to use POST for long URL (+ params).
1085 Added installation instructions for Windows. Note: NT services is
1086 NOT available until we make a new release of YAZ.
1088 Preserve order of repeated metadata fields (they were reversed before).
1090 More MARC21 information extracted for metadata.
1092 --- 1.0.8 2008/04/22
1094 Fixed bug #1162: HTML entities are not escaped properly.
1096 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
1098 --- 1.0.7 2008/04/14
1100 Marc21 stylesheet updated to reflect multiple full text fields
1102 --- 1.0.6 2008/03/12
1104 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1106 Fixed bug 2100: Database wildcards not working
1108 --- 1.0.5 2007/11/09
1110 Added support for retrieval of records in binary.
1112 Fixed bug 1794: Pazpar2 does not return valid XML.
1114 Deal with ICU not returning sortkey (resulted in SEGV before).
1116 --- 1.0.4 2007/09/28
1118 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1119 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1121 Improved diagnostics when Pazpar2 HTTP decoding fails.
1123 Pazpar2 requests may be POSTed as using Content-Type
1124 application/x-www-form-urlencoded.
1126 Pazpar2 honors LF in HTTP headers.
1128 Handle targets that handle negative hit counts (should not happen, but it
1131 --- 1.0.3 2007/09/19
1133 ICU is used for tokenization and normalization of the following: mergekey,
1134 sorting, relevance terms.
1136 Debian package now enables ICU tokenization and normalization by default.
1138 --- 1.0.2 2007/08/22
1140 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1141 ways: Either as parameters to the normalization stylesheets (which would allow the
1142 programmer to postprocess or use the values in any way) or after the normalization
1143 step, in which case values are made part of the normalized record (and available for
1144 sorting, termlists, display, or other interface-related use.
1146 Implemented sorting by year.
1148 Option -d dumps records to the current log file instead of stderr.
1150 Fixes for compilation on cygwin.
1152 Z39.50 client code uses pz:elements. pz:elements was recognized in
1153 earlier Pazpar2 versions but it was not used for anything.
1155 icu_chain_test is using fgets instead of getline - fixes compilation
1158 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1159 query conversions fail (rather than _any_). This means targets that do
1160 not support some fields are ignored in a search.
1162 --- 1.0.1 2007/07/03
1164 Improved handling of socket timeout for Z39.50 connections.
1166 Misc documentation updates and spell fixes.
1168 Debian package pazpar2 creates log rotate entry.
1170 Debian package pazpar2-apache2 reloads Apache2.
1172 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1175 --- 1.0.0 2007/06/20
1177 First public release.
