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

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

231 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
232 It's been like that since version 1.1.1 from August 2009.
234 Add support for result-set caching via memcached. See description of
235 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.

295 Fix issue with hanging show/bytarget. Could happen if new search was
296 fired with filter before show from previous show completed.
298 Add 'date' handling for solr-pz2.xsl.
300 --- 1.6.33 2013/08/13
302 pz:authentication may carry user group password. If pz:authentication
303 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
304 authentication. Two forms are allowed
307 If no blanks are present, open authentication is in use (as before).
309 Fix {prev,next}recid elements that are returned by record
310 command. These were incorrect in versions 1.6.23 thru 1.6.32.
312 --- 1.6.32 2013/06/14
314 Experimental support for snippets. If argument snippets=1 is given
315 for command record or show, the text will include <match>-tags for
316 those area that matches.
318 Fix memory leak WRT client structures (incorrect inc ref count).
320 Log when a HTTP response is serialized and the time elapsed.
322 New command, service, which returns current service XML in use for
325 --- 1.6.31 2013/05/24
327 Local limit for fields of type "generic" (ie text fields) are
328 now normalized by mergekey rule before comparison takes place.
329 Before, no normalization took place and comparsion was, thus, exact.
331 New facility: dynamic rank , which allows ranking to be changed
332 for an existing result set. The rank can be set for search or
333 show. This overrides the rank for metadata elements (which fields
336 New facility:dynamic mergekey , which allows mergekey to be changed
337 for an existing result set. The mergekey can be set for search or
340 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
341 Also, allow ports to be given as names (not just integers).
342 Fix @-notation on systems that don't support IPV6 sockets.

346 Add MasterKey Connect configuration. Refer to section "non-standard
347 databases" for more information.
349 Allow timeformat for log to be specified with option -m (as Metaproxy
352 New Debian package pazpar2-dbg.
354 Fix NULL ptr reference of se->relevance. If a new search is initiated
355 and a CCL query fails to parse, Pazpar2 could crash.
357 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
358 existed in 1.6.29 only.
360 --- 1.6.29 2013/04/05
362 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
363 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
364 changed by setting "host" attribute for the "listen" element.
366 Change semantics of pz:extendrecs. Allow for repeated fetches .
367 pz:extendrecs is now the number of extra records to fetch (was total
370 --- 1.6.28 2013/03/21
372 Fix hang or memory violation if show occurred before a search. (not that
373 it makes much sense to perform a show before a search).
375 --- 1.6.27 2013/03/08
377 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
380 --- 1.6.26 2013/03/08
382 New pz:metadata attribute, empty="empty-value" for Pazpar2's
383 internal representation. With this attribute, Pazpar2 treates an empty
384 pz:metadata type as having the value for "empty" - if empty.
386 New setting, pz:extendrecs, which triggers extended fetch of records
387 for a database beyond pz:maxrecs for a show command.
389 Fix warning that was falsely issued for "missing limitmap".
391 Log message for Pazpart start/stop changed. Now using same style as
392 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
394 --- 1.6.25 2013/02/07
396 Fix hang of 2nd command=show with esn/syntax given.
398 --- 1.6.24 2013/01/18
400 New merge attribute type: 'first', which takes all metadata fields
401 from first target that returns the particular field.
403 --- 1.6.23 2013/01/02
405 Extend info command with hostname and YAZ SHA1
406 Indent results for both command stat and info.
408 Allow limit on merged content. The new configuration metadata
409 element, limitcluster, configures that a metadata element (name) be used
410 as limit name for search. Applies to the whole service (ie all targets),
411 unlike pz:limitmap which is configured per-target (database).
413 New feature: limitmap local:* matches against all metadata fields.
415 Allow repeated list in limitmap spec . Separated by comma. For
416 example: value="local:title,rpn:@attr 1=4".
418 New element <message> in bytarget response. Holds diagnostic message
419 of code (say 'Unsupported Use Attribute' for Bib-1 114).
421 Improved logging for record ingestion failures.
423 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
424 when YAZ is compiled without ICU support.
426 --- 1.6.22 2012/10/11
428 Requires YAZ-4.2.40 to support native solr support.
430 Fix and improve logic handling whether or not to re-do search on sort
431 order changes. A sort order with change in ascending/descending only
432 whould not trigger a new search, which is required for targets with
433 native sorting capabilities. Each client is now checked if instructions
434 (sortmap) exist for native sorting and only client that does requires
435 it is researched. Other clients is just re-ingesting the records,
436 they already have. The resultset is now cleared if any researching
439 Connection sharing between session has broken since version 1.6.8 with
440 introduction of logic that would minimize searching if pazpar2 could
441 detect this based on same query and limits and partly sort order.
442 This could lead to segementations violations.
444 Added a chapter in the manaul about relevance ranking.
446 --- 1.6.21 2012/09/24
448 Rank tweak: follow=number will increase mult by number if two terms
449 occur next to each other; number-1 if they are one term apart , .. 0
450 if they are number a part (all in order). Default is 0 (following
451 terms has no effect).
453 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
454 value given by lead and l is length from beginning of field where
455 term occurs (l=0 for first term, l=1 for second term, ..). Default
458 Rank tweak: length=strategy. length="linear" if mult is to be divided
459 by length (existing, default behavior), length="log" if mult is to be
460 divided by log2(1+length), length="none" if mult is not to be affected
463 --- 1.6.20 2012/09/21
465 Rank algorithm details may be printed as part of show response in
466 element <relevance_info>.. This is only printed if <rank debug="yes"/>
469 Record as returned by show/record command have a minimal indentation
470 which makes things human-readable.
472 New configuration of default sorting criteria (sort-default) in
473 service definition. If no criteria is defined it will be as before
476 Search command now supports sort parameter just as the show command.
477 If no parameter is give, it will use the service sort-default value.
479 --- 1.6.19 2012/09/18
481 Rank algorithm skips strings that gets normalized to empty string.
482 For example, & and ! could map to the empty string. The weight for
483 those terms is now 0 (as if they were not part of the query).
485 Rank algorithm does not use CCL from limitmap; only from the query
486 parameter (user query).
490 --- 1.6.18 2012/09/17
492 Rank algorithm configurable by 'rank' element inside service. So far
493 only, attribute 'cluster' is recognized. If cluster="yes", multiple
494 records inside a cluster boosts higher than single records. This
495 is default behavior and existing behavior. cluster="no" takes the
496 average score of each record in a cluster.
498 --- 1.6.17 2012/09/05
500 Fix bad re-use of connections (connections with changing proxy should not
503 --- 1.6.16 2012/08/22
505 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
506 resultset and sorting when the sort order is position. However this will be done on
507 every client poll, which will make pazpar2 continuing reset and fetching.
508 It should only be done on FIRST request where the sort order change.
510 Fix an issue on suggestion option: Also disable suggestions on empty string.
512 Clean up in turbo marc stylesheet.
514 Remove the hardcoded size of termlists.
516 --- 1.6.15 2012/06/27
518 New facility: ccldirective may be given in service definition. Allows
519 CCL parsing to be customized a bit, such as defining names of operators
522 New facility: raw record by checksum, rather than offset. The record
523 command optionally takes checksum which identifies certain record from
526 New facility: per field ranking. Rank may be given as M [F N] where
527 M is default rank and N is rank for CCL terms from field F.
529 --- 1.6.14 2012/06/04
531 Fix for IE7/8 in pz.js
533 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
535 Lower log level some places.
537 Remove some invalid test results.
539 --- 1.6.13 2012/05/23
541 Introducing a version=2 parameter for show, termlist and bytarget commands.
542 This enables pazpar2 to return approximation on hit and count count when
543 doing record filtering using the limit parameter on search and a
544 limitmap with a value of "local:"
546 Setting pz:xslt may embed local XSLT as an alternative to referring
548 Value is not CDATA but XML nodes embedded, so escaping is not necessary
549 but a root element *must* be present. For example:
550 <settings target="target="z3950.indexdata.com/marc">
559 Metadata field rank may given by XML internal document (pz:xslt
560 result). If rank is not given, the rank from service description is
563 Metadata field can now configured a default limitmap and facetmap.
564 Setting limitmap to "local:" would work for all kind of targets, but would
565 prob. not be the optimal solution. But at least better than the default behavior
566 of pazpar2 where no filtering is done.
568 A service definition can now also contains <set/> that defines service-wide
569 settings. These will override server-wide sets and will be overridded by
572 New setting, pz:present_chunk, that specifies number of records to fetch
573 at a time. Zero will disable chunkation; will fetch max_records at once.
575 --- 1.6.12 2012/03/14
577 Revert the format change in termlist response, that could break
578 some clients / UIs since they were expecting an (empty) element
579 if no facet values was found.
581 --- 1.6.11 2012/03/07
583 Revert the behavior of returning errors when unable to block
584 on termlist, bytarget and search, when unable to block due to
585 other block. The client will now receive a regular response,
586 but it will be logged in the server. A parameter (report) is
587 added to change behavior to return error response or WARNING
588 status message. Consider this "API" as private, as it is mostly
589 untested and could be changed in future releases.
591 Fix spell error in pz2.js fix in 1.6.10.
593 New Marc2TurboMarc.xsl (contribution from Sven Porst).
594 Can solve the missing marc21.xsl updates in some cases.
596 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
597 substring (contribtion from Sven Porst)
599 marc21.xsl: fix 1-based substring call
601 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
603 Add test_termlist_block to test suite
605 --- 1.6.10 2012/02/23
607 Fix SEGV for invalid PQFs and SRU/SOLR targets
608 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
610 Fix pz2.js: "null object" due to change in in bytarget result XML.
612 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
613 Added this normalization to the other subject-long fields (d6xx),
614 where it was missing.
616 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
617 Still differences around medium and holdings. marc21.xsl is not
618 longer active used by Index Data, and should be considered unsupported.
619 Use tmarc.xsl instead.
623 Fix SEGV that could occur for failed connections.
627 Fix bug for command sort that could return no results for active clients
628 (from previous search). This bug was present in 1.6.6-1.6.7.
630 Fix bug in results that could include results that should have been
631 filtered out. This bug was present in 1.6.6-1.6.7.
635 Fix bug introduced in 1.6.6 where a connection re-use could stall
638 Local filtering may now specify a local metadata field, eg.
639 pz:limitmap:somefield[t]=local:otherfield
643 For search, when limit and or filtering is in place and search
644 is identical to previous search, the result set is re-used and the
645 target is not searched.
647 Limits may work perform local filtering as well, by using "local:"
652 Updated bytarget command to contain a suggestions element with misspelled
653 words and suggestions to these. pz2.js has been updated to deliver this
654 onwards as well. Only target that currently delivers this is the solr
655 client in YAZ 4.2.18.
659 New service definition element, xslt, that allows an embedded stylesheet
660 to be defined. This can be referred to from pz:xslt as an alternative to
663 New pz:sortmap:field setting for specifying hints on how to make
664 a target natively sort on a field. This is used for command=show in
665 conjunction with sort.
667 New pz:url setting for specifying the actual URL for a target. When
668 this is used the target ID is not used as URL anymore and the target ID
669 may be almost any string (not including []).
671 command=termlist without name parameter returns all termlists/facets.
672 Previously if name parameter was omitted, only "subject" was returned.
676 Make termlist sorting stable. Terms with same frequency are now sorted by
677 their display name. This makes a pretty display and improves our
678 regression test because qsort is not a stable sort.
680 New sort parameter value 'position'. The 'position' sorts merged records
681 by their original position from the remote target. This is primarily useful
682 for debugging and may be used for targets that already perform some kind
683 of relevance ranking. Note that sort by default is decreasing; so to get
684 records in their original order sort=position:1 must be used.
688 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
690 Facility to change working directory for pazpar2 daemon. Option -wdir
691 sets working directory to dir. This facility is useful if core dumps
692 must be saved. In this case, the current working directory must be
693 writable by the running user, such as "nobody".
697 New configuration element <icu_chain> for <server>/<service> which
698 allows a named ICU rule (chain) to be defined. The names relevance,
699 sort, mergekey and facet are used for those operations. The definition
700 <icu_chain id="sort" locale="en"> .. </icu_chain>
702 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
703 And so on.. for relevance, mergekey and facet as well. The latter
704 style is deprecated. The facet terms are normalized by the facet
705 rule by default. This may be changed on a metadata field basis by
706 defining the new attribute 'facetrule' for the metadata element.
708 <icu_chain id="myrule" locale="en"> ... </icu_chain>
709 <metadata name="author" termlist="yes" facetrule="myrule"/>
711 Preserve rorder for merged metadata. Fixes issue as reported by Sven
712 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
714 tmarc.xsl: set journal-subpart to 773$ only.
718 Modify the behavior for the limit parameter (first defined in 1.5.7).
719 Mapping of limit searches are now defined by the new configuration item
720 pz:limitmap. Fix a dead-lock problem with the limit parameter.
722 Extend tmarc.xsl to extract 773$g data (OpenURL).
726 ICU default maps remove backquote (`).
728 Command 'search' takes limit parameter (optional). The limit parameter
729 allows a search to be limited one or more facets and the corresponding
730 values. This is for server side filtering.
732 Configure tweak: Use -lm for log(3) if needed
736 Fix a problem with skiparticle sortkey that could be completely
737 ignored (and reduced to "").
739 Fix dependency problem in pazpar2 RPM package (did not require
740 libyaz4 as it should).
744 Fix memory leak that occurred for command=termlist&name=xtargets .
746 Pazpar2 may save HTTP requests. Enabled by option -R.
750 Experimental support for DTIC DADS target. New dads-pz2.xsl.
752 Support for query_syntax (overrides the default for SRU | Z39.50)
754 Support for extraArgs (ZOOM "extraArgs" option) for targets
756 New commands: status-server and status-session
760 Fix for threaded runs: Client now have a copy of the database URL,
761 which can used after the database has been release from the client.
762 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
764 tmarc.xsl: Add journal-title-abbrev and full text.
766 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
768 Fix for cmd=record before search.
770 Session Logging clean up.
772 Fix wrong termlist factor when maxrecs is different from 100.
776 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
777 Term factor is default enabled but can be diseabled by
778 pz:termlist_term_factor=0
782 Add scaling of facet count. Currently always enabled, needs fixing.
783 Allow user-defined info for target suffix. This has no meaning in
784 Pazpar2 except to distinguish targets from each other. The suffix
785 data begins with #. For example z3950.indexdata.com/gils#Mydata
787 Added exact-match recordfilter; format name=value
791 SOLR support. Pazpar2 may operate as web service client for SOLR.
795 Fix for show command and block=1 (dead lock). Bug was introduced in
800 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
801 tested on CentOS 5.5 only.
805 Fix problem with result sets being removed from a client session
806 if the connection for it was resused by another session. Bug #3489.
808 New iphone UI for Pazpar2 (www/iphone).
812 Fixes for threaded operation.
814 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
816 New example services in etc/services in source. In the Debian packages
817 these are located in /etc/pazpar2/services-available
819 Threaded mode operational on Windows. Requires Windows 7 or Windows
822 Default value of setting pz:max_connections is 0 which means that there
823 is no limit on number of connections.
827 Pazpar2 may operate in threaded mode. Enabled by element threads in
828 the configuration. See pazpar2_conf for details.
830 New setting setting: pz:max_connections. Setting pz:max_connections is
831 a limit of number of sockets to a host. When this limit is reached,
832 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
833 The client will be marked Client_Error when it can not be searched
834 (other clients in a session may work). If pz:max_connections is not set
835 for a target, a value of 30 will be used. Note: the pz:max_connections
836 will only work in threaded mode.
838 pz2.js: JSON support for show.
840 Debian package: Enable default service, default.xml, before starting
841 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
845 Debian version depends on on libyaz4. Note that Pazpar2 will still
846 compile from source with YAZ 3.
848 Split services into separate files. The example configuration file
849 pazpar2.cfg.dist now includes a default service default.xml (part of
850 etc). And default.xml includes settings/edu.xml. The default.xml file,
851 not to be confused with settings/defaults.xml, is a template for jsdemo
852 and other services. The Debian package installs /etc/pazpar2/server.xml
853 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
854 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
855 The default.xml (from etc) is installed in /etc/pazpar2/services-available
856 and a symlink to it is created from services-enabled. The default.xml
857 service is unnamed and, thus, will be used by jsdemo and test1.
859 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
860 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
864 Support for additional fields in cf.xsl and pazpar2.conf.dist:
865 publisher, available, due, location (=locallocation), callno
866 (=callnumber), thumburl and score.
868 Describe pz:xslt and the auto setting.
870 Move mergekey definition away from the normalization stylesheets and
871 define a mergekey common for all target types in pazpar2.cfg.
873 Code update: Use the Odr_int type for hit counts. This is part of
874 YAZ 3.0.47 and later and so configure checks for that.
878 Metadata attribute 'skiparticle' also works for ICU based
879 normalization. (was only working for the non-ICU/ASCII before).
881 Command bytarget with argument settings=1 will show settings per
882 target.. This is to be able to verify correct settings and be able to
883 test that they are correct. The database settings array size is now
884 also stored.. Problems with database settings array is that if not
885 careful it will be too small (smaller than dictionary per-service
888 Make record list sorting stable by comparing mergekey for records if
889 relevance/title or other sorting criteria all match. This is merely to
890 ensure that our regressions tests works (reproducible output).
892 Relevance calculation changes: use a different denominator (length) for
893 per-field relevance scoring.. Instead of length of all ranked fields we
894 now use length of individual fields (as if they were individual "free"
895 text fields). This will ensure that documents with a long field with no
896 match (say description) will not "hurt" a title match.
898 Diagnostic member was not set on connection error. Fixed
902 Command search takes two optional parameters, startecs and maxrecs,
903 that specifies the start offset (0, 1, ...) and maximum number of records
904 to fetch for each target.
906 XSLTs + MARC maps are cached within a session so we don't re-parse
907 them over and over again. Even for a session with a single search
908 there's much to be gained because many targets use the same
911 The metadata attribute 'mergekey' now takes one of three values 'no',
912 'required', 'optional' . And the resulting mergekey from metadata
913 is now ordered in the same way as metadata in the service definition.
914 Older Pazpar2 version use the order in which metadata appeared in a
917 The search argument 'filter' now offers a new operator ~ which does a
918 substring match. The = operator works as before: string match for
919 anything but pz:id, or target match for pz:id.
921 New setting pz:recordfilter. The value of this setting takes the
922 form name[~value]. This setting makes Pazpar2 ignore all retrieved
923 records that do not have the metadata element name with value substring
926 Pazpar2 allows YAZ log level to be set (option -v).
930 For WS responses Pazpar2 creates XML header. Exception: raw record.
932 Setting XML files are now stored in etc/settings instead of etc. This
933 reflects the layout with the Debian package layout.
935 Settings may be posted for command=settings. The POSTed settings must
936 have root element 'settings' like regular setting files. In order to be
937 recognized, the POST request must use Content-Type=text/xml.
939 A service may be posted for command=init. This service will be used
940 during the session. The service may have its own target settings,
941 ICU config, timeout, etc. In order to be recognized, the POST request
942 must use Content-Type=text/xml.
944 Timeout values may be given per-service. That's element 'timeout'
945 which takes three attribute values (a subset may be given): 'session',
946 'z3950_operation', 'z3950_session'. Option -T is no longer supported
947 - used to specify session timeout.
949 Option -t tests the Pazpar2 configuration and returns exit code
950 (0=success, non-zero=failure). In previous version of Pazpar2, -t
951 specified local settings.
953 In version 1.2.0 the configuration file - after include processing -
954 was dumped to stdout. Now, the configuration is only dumped to the
955 yaz log file if option -d is given.
959 Configuration may now have multiple server areas. This means that a
960 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
961 yet supported - on a server basis. Configuration may also have multiple
962 services .. That is repeating service elements inside a server. Each
963 has an attribute 'id' which serves as service ID. This ID in turn may
964 be used in a Pazpar2 session, by specifying parameter service=ID for
965 command init. There can be at most one unnamed service inside a server
966 which can be referred to by not specifying an service ID for command
967 init (backwards compatible). In order to partition multiple servers and
968 services a new include directive has been added. This takes an attribute
969 'src' which specifies one or more sub-files. For example to include
970 service files, one might use:
971 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
972 It is the intention that that completely makes the settings directive
975 Fix problem where the record command would wait forever if there were
976 no targets to wait for (activeclients == 0).
980 One result set is created per session (last search) rather than for
981 each connection which happen to be shared (bug #3009).
983 marc21 stylesheets changed for efficiency.
987 Session timeout may be specified on the command-line as option -T.
989 Pazpar2 may now be operated in a no-merged mode for records.. All records
990 will be considered unique. This mode is enabled if no mergekey is
991 generated by the normalization stylesheet (pz:xslt).
993 Pazpar2 caches original records from each target and the 'record' command
994 with offset returns the original record if 'syntax' and 'esn' are NOT
995 specified. This speeds up retrieval of original records but also means
996 that Pazpar2 uses more memory. The cached records will be freed when the
997 session terminates or a new search is executed.
999 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
1000 library part of YAZ is used.
1002 Added SRU client support.
1004 Automatically computes pz:nativesyntax if not provided. Works for XML and
1007 --- 1.0.13 2008/11/24
1009 Command bytarget returns name of target (if defined).
1011 --- 1.0.12 2008/11/04
1013 Fixed bug #2021.. location now holds all brief elements.
1015 --- 1.0.11 2008/10/15
1017 Fixed check for application/x-www-form-urlencoded parameters.
1019 --- 1.0.10 2008/10/14
1021 Fixes for IE in pz2.js.
1023 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
1025 --- 1.0.9 2008/05/23
1027 Changed the JS library pz2.js to use POST for long URL (+ params).
1029 Added installation instructions for Windows. Note: NT services is
1030 NOT available until we make a new release of YAZ.
1032 Preserve order of repeated metadata fields (they were reversed before).
1034 More MARC21 information extracted for metadata.
1036 --- 1.0.8 2008/04/22
1038 Fixed bug #1162: HTML entities are not escaped properly.
1040 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
1042 --- 1.0.7 2008/04/14
1044 Marc21 stylesheet updated to reflect multiple full text fields
1046 --- 1.0.6 2008/03/12
1048 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1050 Fixed bug 2100: Database wildcards not working
1052 --- 1.0.5 2007/11/09
1054 Added support for retrieval of records in binary.
1056 Fixed bug 1794: Pazpar2 does not return valid XML.
1058 Deal with ICU not returning sortkey (resulted in SEGV before).
1060 --- 1.0.4 2007/09/28
1062 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1063 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1065 Improved diagnostics when Pazpar2 HTTP decoding fails.
1067 Pazpar2 requests may be POSTed as using Content-Type
1068 application/x-www-form-urlencoded.
1070 Pazpar2 honors LF in HTTP headers.
1072 Handle targets that handle negative hit counts (should not happen, but it
1075 --- 1.0.3 2007/09/19
1077 ICU is used for tokenization and normalization of the following: mergekey,
1078 sorting, relevance terms.
1080 Debian package now enables ICU tokenization and normalization by default.
1082 --- 1.0.2 2007/08/22
1084 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1085 ways: Either as parameters to the normalization stylesheets (which would allow the
1086 programmer to postprocess or use the values in any way) or after the normalization
1087 step, in which case values are made part of the normalized record (and available for
1088 sorting, termlists, display, or other interface-related use.
1090 Implemented sorting by year.
1092 Option -d dumps records to the current log file instead of stderr.
1094 Fixes for compilation on cygwin.
1096 Z39.50 client code uses pz:elements. pz:elements was recognized in
1097 earlier Pazpar2 versions but it was not used for anything.
1099 icu_chain_test is using fgets instead of getline - fixes compilation
1102 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1103 query conversions fail (rather than _any_). This means targets that do
1104 not support some fields are ignored in a search.
1106 --- 1.0.1 2007/07/03
1108 Improved handling of socket timeout for Z39.50 connections.
1110 Misc documentation updates and spell fixes.
1112 Debian package pazpar2 creates log rotate entry.
1114 Debian package pazpar2-apache2 reloads Apache2.
1116 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1119 --- 1.0.0 2007/06/20
1121 First public release.
