114 Both citation and journal-subpart have same value.
118 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
121 Remove from js/pz2.js the code that translates just two diagnostic
122 codes (1 and 2) into human-readable messages. This is no longer
123 necessary at all, as PazPar2 has been returning the message as well as
124 the code in its responses since December 2012. Fixes PAZ-978.

166 Report number of filtered records in bytarget PAZ-954
168 Cache XML documents as they appear after normalization. The key
169 for the cache is database+record offset. Cache is removed if query

235 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
236 It's been like that since version 1.1.1 from August 2009.
238 Add support for result-set caching via memcached. See description of
239 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
241 Add support for a <metadata> container tag. Patfh from Sven Porst.
243 Add support for XInclude in main configuarion file. Patch from Sven Porst.
245 Add client_{lock,unlock} before call to non_block_events in

299 Fix issue with hanging show/bytarget. Could happen if new search was
300 fired with filter before show from previous show completed.
302 Add 'date' handling for solr-pz2.xsl.
304 --- 1.6.33 2013/08/13
306 pz:authentication may carry user group password. If pz:authentication
307 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
308 authentication. Two forms are allowed
311 If no blanks are present, open authentication is in use (as before).
313 Fix {prev,next}recid elements that are returned by record
314 command. These were incorrect in versions 1.6.23 thru 1.6.32.
316 --- 1.6.32 2013/06/14
318 Experimental support for snippets. If argument snippets=1 is given
319 for command record or show, the text will include <match>-tags for
320 those area that matches.
322 Fix memory leak WRT client structures (incorrect inc ref count).
324 Log when a HTTP response is serialized and the time elapsed.
326 New command, service, which returns current service XML in use for
329 --- 1.6.31 2013/05/24
331 Local limit for fields of type "generic" (ie text fields) are
332 now normalized by mergekey rule before comparison takes place.
333 Before, no normalization took place and comparsion was, thus, exact.
335 New facility: dynamic rank , which allows ranking to be changed
336 for an existing result set. The rank can be set for search or
337 show. This overrides the rank for metadata elements (which fields
340 New facility:dynamic mergekey , which allows mergekey to be changed
341 for an existing result set. The mergekey can be set for search or
344 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
345 Also, allow ports to be given as names (not just integers).
346 Fix @-notation on systems that don't support IPV6 sockets.
348 --- 1.6.30 2013/04/26
350 Add MasterKey Connect configuration. Refer to section "non-standard
351 databases" for more information.
353 Allow timeformat for log to be specified with option -m (as Metaproxy
356 New Debian package pazpar2-dbg.
358 Fix NULL ptr reference of se->relevance. If a new search is initiated
359 and a CCL query fails to parse, Pazpar2 could crash.
361 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
362 existed in 1.6.29 only.
364 --- 1.6.29 2013/04/05
366 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
367 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
368 changed by setting "host" attribute for the "listen" element.
370 Change semantics of pz:extendrecs. Allow for repeated fetches .
371 pz:extendrecs is now the number of extra records to fetch (was total
374 --- 1.6.28 2013/03/21
376 Fix hang or memory violation if show occurred before a search. (not that
377 it makes much sense to perform a show before a search).
379 --- 1.6.27 2013/03/08
381 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
384 --- 1.6.26 2013/03/08
386 New pz:metadata attribute, empty="empty-value" for Pazpar2's
387 internal representation. With this attribute, Pazpar2 treates an empty
388 pz:metadata type as having the value for "empty" - if empty.
390 New setting, pz:extendrecs, which triggers extended fetch of records
391 for a database beyond pz:maxrecs for a show command.
393 Fix warning that was falsely issued for "missing limitmap".
395 Log message for Pazpart start/stop changed. Now using same style as
396 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
398 --- 1.6.25 2013/02/07
400 Fix hang of 2nd command=show with esn/syntax given.
402 --- 1.6.24 2013/01/18
404 New merge attribute type: 'first', which takes all metadata fields
405 from first target that returns the particular field.
407 --- 1.6.23 2013/01/02
409 Extend info command with hostname and YAZ SHA1
410 Indent results for both command stat and info.
412 Allow limit on merged content. The new configuration metadata
413 element, limitcluster, configures that a metadata element (name) be used
414 as limit name for search. Applies to the whole service (ie all targets),
415 unlike pz:limitmap which is configured per-target (database).
417 New feature: limitmap local:* matches against all metadata fields.
419 Allow repeated list in limitmap spec . Separated by comma. For
420 example: value="local:title,rpn:@attr 1=4".
422 New element <message> in bytarget response. Holds diagnostic message
423 of code (say 'Unsupported Use Attribute' for Bib-1 114).
425 Improved logging for record ingestion failures.
427 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
428 when YAZ is compiled without ICU support.
430 --- 1.6.22 2012/10/11
432 Requires YAZ-4.2.40 to support native solr support.
434 Fix and improve logic handling whether or not to re-do search on sort
435 order changes. A sort order with change in ascending/descending only
436 whould not trigger a new search, which is required for targets with
437 native sorting capabilities. Each client is now checked if instructions
438 (sortmap) exist for native sorting and only client that does requires
439 it is researched. Other clients is just re-ingesting the records,
440 they already have. The resultset is now cleared if any researching
443 Connection sharing between session has broken since version 1.6.8 with
444 introduction of logic that would minimize searching if pazpar2 could
445 detect this based on same query and limits and partly sort order.
446 This could lead to segementations violations.
448 Added a chapter in the manaul about relevance ranking.
450 --- 1.6.21 2012/09/24
452 Rank tweak: follow=number will increase mult by number if two terms
453 occur next to each other; number-1 if they are one term apart , .. 0
454 if they are number a part (all in order). Default is 0 (following
455 terms has no effect).
457 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
458 value given by lead and l is length from beginning of field where
459 term occurs (l=0 for first term, l=1 for second term, ..). Default
462 Rank tweak: length=strategy. length="linear" if mult is to be divided
463 by length (existing, default behavior), length="log" if mult is to be
464 divided by log2(1+length), length="none" if mult is not to be affected
467 --- 1.6.20 2012/09/21
469 Rank algorithm details may be printed as part of show response in
470 element <relevance_info>.. This is only printed if <rank debug="yes"/>
473 Record as returned by show/record command have a minimal indentation
474 which makes things human-readable.
476 New configuration of default sorting criteria (sort-default) in
477 service definition. If no criteria is defined it will be as before
480 Search command now supports sort parameter just as the show command.
481 If no parameter is give, it will use the service sort-default value.
483 --- 1.6.19 2012/09/18
485 Rank algorithm skips strings that gets normalized to empty string.
486 For example, & and ! could map to the empty string. The weight for
487 those terms is now 0 (as if they were not part of the query).
489 Rank algorithm does not use CCL from limitmap; only from the query
490 parameter (user query).
494 --- 1.6.18 2012/09/17
496 Rank algorithm configurable by 'rank' element inside service. So far
497 only, attribute 'cluster' is recognized. If cluster="yes", multiple
498 records inside a cluster boosts higher than single records. This
499 is default behavior and existing behavior. cluster="no" takes the
500 average score of each record in a cluster.
502 --- 1.6.17 2012/09/05
504 Fix bad re-use of connections (connections with changing proxy should not
507 --- 1.6.16 2012/08/22
509 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
510 resultset and sorting when the sort order is position. However this will be done on
511 every client poll, which will make pazpar2 continuing reset and fetching.
512 It should only be done on FIRST request where the sort order change.
514 Fix an issue on suggestion option: Also disable suggestions on empty string.
516 Clean up in turbo marc stylesheet.
518 Remove the hardcoded size of termlists.
520 --- 1.6.15 2012/06/27
522 New facility: ccldirective may be given in service definition. Allows
523 CCL parsing to be customized a bit, such as defining names of operators
526 New facility: raw record by checksum, rather than offset. The record
527 command optionally takes checksum which identifies certain record from
530 New facility: per field ranking. Rank may be given as M [F N] where
531 M is default rank and N is rank for CCL terms from field F.
533 --- 1.6.14 2012/06/04
535 Fix for IE7/8 in pz.js
537 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
539 Lower log level some places.
541 Remove some invalid test results.
543 --- 1.6.13 2012/05/23
545 Introducing a version=2 parameter for show, termlist and bytarget commands.
546 This enables pazpar2 to return approximation on hit and count count when
547 doing record filtering using the limit parameter on search and a
548 limitmap with a value of "local:"
550 Setting pz:xslt may embed local XSLT as an alternative to referring
552 Value is not CDATA but XML nodes embedded, so escaping is not necessary
553 but a root element *must* be present. For example:
554 <settings target="target="z3950.indexdata.com/marc">
563 Metadata field rank may given by XML internal document (pz:xslt
564 result). If rank is not given, the rank from service description is
567 Metadata field can now configured a default limitmap and facetmap.
568 Setting limitmap to "local:" would work for all kind of targets, but would
569 prob. not be the optimal solution. But at least better than the default behavior
570 of pazpar2 where no filtering is done.
572 A service definition can now also contains <set/> that defines service-wide
573 settings. These will override server-wide sets and will be overridded by
576 New setting, pz:present_chunk, that specifies number of records to fetch
577 at a time. Zero will disable chunkation; will fetch max_records at once.
579 --- 1.6.12 2012/03/14
581 Revert the format change in termlist response, that could break
582 some clients / UIs since they were expecting an (empty) element
583 if no facet values was found.
585 --- 1.6.11 2012/03/07
587 Revert the behavior of returning errors when unable to block
588 on termlist, bytarget and search, when unable to block due to
589 other block. The client will now receive a regular response,
590 but it will be logged in the server. A parameter (report) is
591 added to change behavior to return error response or WARNING
592 status message. Consider this "API" as private, as it is mostly
593 untested and could be changed in future releases.
595 Fix spell error in pz2.js fix in 1.6.10.
597 New Marc2TurboMarc.xsl (contribution from Sven Porst).
598 Can solve the missing marc21.xsl updates in some cases.
600 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
601 substring (contribtion from Sven Porst)
603 marc21.xsl: fix 1-based substring call
605 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
607 Add test_termlist_block to test suite
609 --- 1.6.10 2012/02/23
611 Fix SEGV for invalid PQFs and SRU/SOLR targets
612 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
614 Fix pz2.js: "null object" due to change in in bytarget result XML.
616 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
617 Added this normalization to the other subject-long fields (d6xx),
618 where it was missing.
620 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
621 Still differences around medium and holdings. marc21.xsl is not
622 longer active used by Index Data, and should be considered unsupported.
623 Use tmarc.xsl instead.
627 Fix SEGV that could occur for failed connections.
631 Fix bug for command sort that could return no results for active clients
632 (from previous search). This bug was present in 1.6.6-1.6.7.
634 Fix bug in results that could include results that should have been
635 filtered out. This bug was present in 1.6.6-1.6.7.
639 Fix bug introduced in 1.6.6 where a connection re-use could stall
642 Local filtering may now specify a local metadata field, eg.
643 pz:limitmap:somefield[t]=local:otherfield
647 For search, when limit and or filtering is in place and search
648 is identical to previous search, the result set is re-used and the
649 target is not searched.
651 Limits may work perform local filtering as well, by using "local:"
656 Updated bytarget command to contain a suggestions element with misspelled
657 words and suggestions to these. pz2.js has been updated to deliver this
658 onwards as well. Only target that currently delivers this is the solr
659 client in YAZ 4.2.18.
663 New service definition element, xslt, that allows an embedded stylesheet
664 to be defined. This can be referred to from pz:xslt as an alternative to
667 New pz:sortmap:field setting for specifying hints on how to make
668 a target natively sort on a field. This is used for command=show in
669 conjunction with sort.
671 New pz:url setting for specifying the actual URL for a target. When
672 this is used the target ID is not used as URL anymore and the target ID
673 may be almost any string (not including []).
675 command=termlist without name parameter returns all termlists/facets.
676 Previously if name parameter was omitted, only "subject" was returned.
680 Make termlist sorting stable. Terms with same frequency are now sorted by
681 their display name. This makes a pretty display and improves our
682 regression test because qsort is not a stable sort.
684 New sort parameter value 'position'. The 'position' sorts merged records
685 by their original position from the remote target. This is primarily useful
686 for debugging and may be used for targets that already perform some kind
687 of relevance ranking. Note that sort by default is decreasing; so to get
688 records in their original order sort=position:1 must be used.
692 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
694 Facility to change working directory for pazpar2 daemon. Option -wdir
695 sets working directory to dir. This facility is useful if core dumps
696 must be saved. In this case, the current working directory must be
697 writable by the running user, such as "nobody".
701 New configuration element <icu_chain> for <server>/<service> which
702 allows a named ICU rule (chain) to be defined. The names relevance,
703 sort, mergekey and facet are used for those operations. The definition
704 <icu_chain id="sort" locale="en"> .. </icu_chain>
706 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
707 And so on.. for relevance, mergekey and facet as well. The latter
708 style is deprecated. The facet terms are normalized by the facet
709 rule by default. This may be changed on a metadata field basis by
710 defining the new attribute 'facetrule' for the metadata element.
712 <icu_chain id="myrule" locale="en"> ... </icu_chain>
713 <metadata name="author" termlist="yes" facetrule="myrule"/>
715 Preserve rorder for merged metadata. Fixes issue as reported by Sven
716 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
718 tmarc.xsl: set journal-subpart to 773$ only.
722 Modify the behavior for the limit parameter (first defined in 1.5.7).
723 Mapping of limit searches are now defined by the new configuration item
724 pz:limitmap. Fix a dead-lock problem with the limit parameter.
726 Extend tmarc.xsl to extract 773$g data (OpenURL).
730 ICU default maps remove backquote (`).
732 Command 'search' takes limit parameter (optional). The limit parameter
733 allows a search to be limited one or more facets and the corresponding
734 values. This is for server side filtering.
736 Configure tweak: Use -lm for log(3) if needed
740 Fix a problem with skiparticle sortkey that could be completely
741 ignored (and reduced to "").
743 Fix dependency problem in pazpar2 RPM package (did not require
744 libyaz4 as it should).
748 Fix memory leak that occurred for command=termlist&name=xtargets .
750 Pazpar2 may save HTTP requests. Enabled by option -R.
754 Experimental support for DTIC DADS target. New dads-pz2.xsl.
756 Support for query_syntax (overrides the default for SRU | Z39.50)
758 Support for extraArgs (ZOOM "extraArgs" option) for targets
760 New commands: status-server and status-session
764 Fix for threaded runs: Client now have a copy of the database URL,
765 which can used after the database has been release from the client.
766 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
768 tmarc.xsl: Add journal-title-abbrev and full text.
770 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
772 Fix for cmd=record before search.
774 Session Logging clean up.
776 Fix wrong termlist factor when maxrecs is different from 100.
780 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
781 Term factor is default enabled but can be diseabled by
782 pz:termlist_term_factor=0
786 Add scaling of facet count. Currently always enabled, needs fixing.
787 Allow user-defined info for target suffix. This has no meaning in
788 Pazpar2 except to distinguish targets from each other. The suffix
789 data begins with #. For example z3950.indexdata.com/gils#Mydata
791 Added exact-match recordfilter; format name=value
795 SOLR support. Pazpar2 may operate as web service client for SOLR.
799 Fix for show command and block=1 (dead lock). Bug was introduced in
804 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
805 tested on CentOS 5.5 only.
809 Fix problem with result sets being removed from a client session
810 if the connection for it was resused by another session. Bug #3489.
812 New iphone UI for Pazpar2 (www/iphone).
816 Fixes for threaded operation.
818 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
820 New example services in etc/services in source. In the Debian packages
821 these are located in /etc/pazpar2/services-available
823 Threaded mode operational on Windows. Requires Windows 7 or Windows
826 Default value of setting pz:max_connections is 0 which means that there
827 is no limit on number of connections.
831 Pazpar2 may operate in threaded mode. Enabled by element threads in
832 the configuration. See pazpar2_conf for details.
834 New setting setting: pz:max_connections. Setting pz:max_connections is
835 a limit of number of sockets to a host. When this limit is reached,
836 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
837 The client will be marked Client_Error when it can not be searched
838 (other clients in a session may work). If pz:max_connections is not set
839 for a target, a value of 30 will be used. Note: the pz:max_connections
840 will only work in threaded mode.
842 pz2.js: JSON support for show.
844 Debian package: Enable default service, default.xml, before starting
845 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
849 Debian version depends on on libyaz4. Note that Pazpar2 will still
850 compile from source with YAZ 3.
852 Split services into separate files. The example configuration file
853 pazpar2.cfg.dist now includes a default service default.xml (part of
854 etc). And default.xml includes settings/edu.xml. The default.xml file,
855 not to be confused with settings/defaults.xml, is a template for jsdemo
856 and other services. The Debian package installs /etc/pazpar2/server.xml
857 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
858 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
859 The default.xml (from etc) is installed in /etc/pazpar2/services-available
860 and a symlink to it is created from services-enabled. The default.xml
861 service is unnamed and, thus, will be used by jsdemo and test1.
863 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
864 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
868 Support for additional fields in cf.xsl and pazpar2.conf.dist:
869 publisher, available, due, location (=locallocation), callno
870 (=callnumber), thumburl and score.
872 Describe pz:xslt and the auto setting.
874 Move mergekey definition away from the normalization stylesheets and
875 define a mergekey common for all target types in pazpar2.cfg.
877 Code update: Use the Odr_int type for hit counts. This is part of
878 YAZ 3.0.47 and later and so configure checks for that.
882 Metadata attribute 'skiparticle' also works for ICU based
883 normalization. (was only working for the non-ICU/ASCII before).
885 Command bytarget with argument settings=1 will show settings per
886 target.. This is to be able to verify correct settings and be able to
887 test that they are correct. The database settings array size is now
888 also stored.. Problems with database settings array is that if not
889 careful it will be too small (smaller than dictionary per-service
892 Make record list sorting stable by comparing mergekey for records if
893 relevance/title or other sorting criteria all match. This is merely to
894 ensure that our regressions tests works (reproducible output).
896 Relevance calculation changes: use a different denominator (length) for
897 per-field relevance scoring.. Instead of length of all ranked fields we
898 now use length of individual fields (as if they were individual "free"
899 text fields). This will ensure that documents with a long field with no
900 match (say description) will not "hurt" a title match.
902 Diagnostic member was not set on connection error. Fixed
906 Command search takes two optional parameters, startecs and maxrecs,
907 that specifies the start offset (0, 1, ...) and maximum number of records
908 to fetch for each target.
910 XSLTs + MARC maps are cached within a session so we don't re-parse
911 them over and over again. Even for a session with a single search
912 there's much to be gained because many targets use the same
915 The metadata attribute 'mergekey' now takes one of three values 'no',
916 'required', 'optional' . And the resulting mergekey from metadata
917 is now ordered in the same way as metadata in the service definition.
918 Older Pazpar2 version use the order in which metadata appeared in a
921 The search argument 'filter' now offers a new operator ~ which does a
922 substring match. The = operator works as before: string match for
923 anything but pz:id, or target match for pz:id.
925 New setting pz:recordfilter. The value of this setting takes the
926 form name[~value]. This setting makes Pazpar2 ignore all retrieved
927 records that do not have the metadata element name with value substring
930 Pazpar2 allows YAZ log level to be set (option -v).
934 For WS responses Pazpar2 creates XML header. Exception: raw record.
936 Setting XML files are now stored in etc/settings instead of etc. This
937 reflects the layout with the Debian package layout.
939 Settings may be posted for command=settings. The POSTed settings must
940 have root element 'settings' like regular setting files. In order to be
941 recognized, the POST request must use Content-Type=text/xml.
943 A service may be posted for command=init. This service will be used
944 during the session. The service may have its own target settings,
945 ICU config, timeout, etc. In order to be recognized, the POST request
946 must use Content-Type=text/xml.
948 Timeout values may be given per-service. That's element 'timeout'
949 which takes three attribute values (a subset may be given): 'session',
950 'z3950_operation', 'z3950_session'. Option -T is no longer supported
951 - used to specify session timeout.
953 Option -t tests the Pazpar2 configuration and returns exit code
954 (0=success, non-zero=failure). In previous version of Pazpar2, -t
955 specified local settings.
957 In version 1.2.0 the configuration file - after include processing -
958 was dumped to stdout. Now, the configuration is only dumped to the
959 yaz log file if option -d is given.
963 Configuration may now have multiple server areas. This means that a
964 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
965 yet supported - on a server basis. Configuration may also have multiple
966 services .. That is repeating service elements inside a server. Each
967 has an attribute 'id' which serves as service ID. This ID in turn may
968 be used in a Pazpar2 session, by specifying parameter service=ID for
969 command init. There can be at most one unnamed service inside a server
970 which can be referred to by not specifying an service ID for command
971 init (backwards compatible). In order to partition multiple servers and
972 services a new include directive has been added. This takes an attribute
973 'src' which specifies one or more sub-files. For example to include
974 service files, one might use:
975 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
976 It is the intention that that completely makes the settings directive
979 Fix problem where the record command would wait forever if there were
980 no targets to wait for (activeclients == 0).
984 One result set is created per session (last search) rather than for
985 each connection which happen to be shared (bug #3009).
987 marc21 stylesheets changed for efficiency.
991 Session timeout may be specified on the command-line as option -T.
993 Pazpar2 may now be operated in a no-merged mode for records.. All records
994 will be considered unique. This mode is enabled if no mergekey is
995 generated by the normalization stylesheet (pz:xslt).
997 Pazpar2 caches original records from each target and the 'record' command
998 with offset returns the original record if 'syntax' and 'esn' are NOT
999 specified. This speeds up retrieval of original records but also means
1000 that Pazpar2 uses more memory. The cached records will be freed when the
1001 session terminates or a new search is executed.
1003 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
1004 library part of YAZ is used.
1006 Added SRU client support.
1008 Automatically computes pz:nativesyntax if not provided. Works for XML and
1011 --- 1.0.13 2008/11/24
1013 Command bytarget returns name of target (if defined).
1015 --- 1.0.12 2008/11/04

1023 --- 1.0.10 2008/10/14
1025 Fixes for IE in pz2.js.
1027 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
1029 --- 1.0.9 2008/05/23
1031 Changed the JS library pz2.js to use POST for long URL (+ params).
1033 Added installation instructions for Windows. Note: NT services is
1034 NOT available until we make a new release of YAZ.
1036 Preserve order of repeated metadata fields (they were reversed before).
1038 More MARC21 information extracted for metadata.
1040 --- 1.0.8 2008/04/22
1042 Fixed bug #1162: HTML entities are not escaped properly.
1044 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
1046 --- 1.0.7 2008/04/14
1048 Marc21 stylesheet updated to reflect multiple full text fields
1050 --- 1.0.6 2008/03/12
1052 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1054 Fixed bug 2100: Database wildcards not working
1056 --- 1.0.5 2007/11/09
1058 Added support for retrieval of records in binary.
1060 Fixed bug 1794: Pazpar2 does not return valid XML.
1062 Deal with ICU not returning sortkey (resulted in SEGV before).
1064 --- 1.0.4 2007/09/28
1066 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1067 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1069 Improved diagnostics when Pazpar2 HTTP decoding fails.
1071 Pazpar2 requests may be POSTed as using Content-Type
1072 application/x-www-form-urlencoded.
1074 Pazpar2 honors LF in HTTP headers.
1076 Handle targets that handle negative hit counts (should not happen, but it
1079 --- 1.0.3 2007/09/19
1081 ICU is used for tokenization and normalization of the following: mergekey,
1082 sorting, relevance terms.
1084 Debian package now enables ICU tokenization and normalization by default.
1086 --- 1.0.2 2007/08/22
1088 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1089 ways: Either as parameters to the normalization stylesheets (which would allow the
1090 programmer to postprocess or use the values in any way) or after the normalization
1091 step, in which case values are made part of the normalized record (and available for
1092 sorting, termlists, display, or other interface-related use.
1094 Implemented sorting by year.
1096 Option -d dumps records to the current log file instead of stderr.
1098 Fixes for compilation on cygwin.
1100 Z39.50 client code uses pz:elements. pz:elements was recognized in
1101 earlier Pazpar2 versions but it was not used for anything.
1103 icu_chain_test is using fgets instead of getline - fixes compilation
1106 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1107 query conversions fail (rather than _any_). This means targets that do
1108 not support some fields are ignored in a search.
1110 --- 1.0.1 2007/07/03
1112 Improved handling of socket timeout for Z39.50 connections.
1114 Misc documentation updates and spell fixes.
1116 Debian package pazpar2 creates log rotate entry.
1118 Debian package pazpar2-apache2 reloads Apache2.
1120 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1123 --- 1.0.0 2007/06/20
1125 First public release.
