58 Updates to Windows NMAKE makefile for Visual Studio 2013.
62 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may

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

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

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

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

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

309 Add MasterKey Connect configuration. Refer to section "non-standard
310 databases" for more information.
312 Allow timeformat for log to be specified with option -m (as Metaproxy
315 New Debian package pazpar2-dbg.
317 Fix NULL ptr reference of se->relevance. If a new search is initiated
318 and a CCL query fails to parse, Pazpar2 could crash.
320 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
321 existed in 1.6.29 only.
323 --- 1.6.29 2013/04/05
325 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
326 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
327 changed by setting "host" attribute for the "listen" element.
329 Change semantics of pz:extendrecs. Allow for repeated fetches .
330 pz:extendrecs is now the number of extra records to fetch (was total
333 --- 1.6.28 2013/03/21
335 Fix hang or memory violation if show occurred before a search. (not that
336 it makes much sense to perform a show before a search).
338 --- 1.6.27 2013/03/08
340 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
343 --- 1.6.26 2013/03/08
345 New pz:metadata attribute, empty="empty-value" for Pazpar2's
346 internal representation. With this attribute, Pazpar2 treates an empty
347 pz:metadata type as having the value for "empty" - if empty.
349 New setting, pz:extendrecs, which triggers extended fetch of records
350 for a database beyond pz:maxrecs for a show command.
352 Fix warning that was falsely issued for "missing limitmap".
354 Log message for Pazpart start/stop changed. Now using same style as
355 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
357 --- 1.6.25 2013/02/07
359 Fix hang of 2nd command=show with esn/syntax given.
361 --- 1.6.24 2013/01/18
363 New merge attribute type: 'first', which takes all metadata fields
364 from first target that returns the particular field.
366 --- 1.6.23 2013/01/02
368 Extend info command with hostname and YAZ SHA1
369 Indent results for both command stat and info.
371 Allow limit on merged content. The new configuration metadata
372 element, limitcluster, configures that a metadata element (name) be used
373 as limit name for search. Applies to the whole service (ie all targets),
374 unlike pz:limitmap which is configured per-target (database).
376 New feature: limitmap local:* matches against all metadata fields.
378 Allow repeated list in limitmap spec . Separated by comma. For
379 example: value="local:title,rpn:@attr 1=4".
381 New element <message> in bytarget response. Holds diagnostic message
382 of code (say 'Unsupported Use Attribute' for Bib-1 114).
384 Improved logging for record ingestion failures.
386 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
387 when YAZ is compiled without ICU support.
389 --- 1.6.22 2012/10/11
391 Requires YAZ-4.2.40 to support native solr support.
393 Fix and improve logic handling whether or not to re-do search on sort
394 order changes. A sort order with change in ascending/descending only
395 whould not trigger a new search, which is required for targets with
396 native sorting capabilities. Each client is now checked if instructions
397 (sortmap) exist for native sorting and only client that does requires
398 it is researched. Other clients is just re-ingesting the records,
399 they already have. The resultset is now cleared if any researching
402 Connection sharing between session has broken since version 1.6.8 with
403 introduction of logic that would minimize searching if pazpar2 could
404 detect this based on same query and limits and partly sort order.
405 This could lead to segementations violations.
407 Added a chapter in the manaul about relevance ranking.
409 --- 1.6.21 2012/09/24
411 Rank tweak: follow=number will increase mult by number if two terms
412 occur next to each other; number-1 if they are one term apart , .. 0
413 if they are number a part (all in order). Default is 0 (following
414 terms has no effect).
416 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
417 value given by lead and l is length from beginning of field where
418 term occurs (l=0 for first term, l=1 for second term, ..). Default
421 Rank tweak: length=strategy. length="linear" if mult is to be divided
422 by length (existing, default behavior), length="log" if mult is to be
423 divided by log2(1+length), length="none" if mult is not to be affected
426 --- 1.6.20 2012/09/21
428 Rank algorithm details may be printed as part of show response in
429 element <relevance_info>.. This is only printed if <rank debug="yes"/>
432 Record as returned by show/record command have a minimal indentation
433 which makes things human-readable.
435 New configuration of default sorting criteria (sort-default) in
436 service definition. If no criteria is defined it will be as before
439 Search command now supports sort parameter just as the show command.
440 If no parameter is give, it will use the service sort-default value.
442 --- 1.6.19 2012/09/18
444 Rank algorithm skips strings that gets normalized to empty string.
445 For example, & and ! could map to the empty string. The weight for
446 those terms is now 0 (as if they were not part of the query).
448 Rank algorithm does not use CCL from limitmap; only from the query
449 parameter (user query).
453 --- 1.6.18 2012/09/17
455 Rank algorithm configurable by 'rank' element inside service. So far
456 only, attribute 'cluster' is recognized. If cluster="yes", multiple
457 records inside a cluster boosts higher than single records. This
458 is default behavior and existing behavior. cluster="no" takes the
459 average score of each record in a cluster.
461 --- 1.6.17 2012/09/05
463 Fix bad re-use of connections (connections with changing proxy should not
466 --- 1.6.16 2012/08/22
468 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
469 resultset and sorting when the sort order is position. However this will be done on
470 every client poll, which will make pazpar2 continuing reset and fetching.
471 It should only be done on FIRST request where the sort order change.
473 Fix an issue on suggestion option: Also disable suggestions on empty string.
475 Clean up in turbo marc stylesheet.
477 Remove the hardcoded size of termlists.
479 --- 1.6.15 2012/06/27
481 New facility: ccldirective may be given in service definition. Allows
482 CCL parsing to be customized a bit, such as defining names of operators
485 New facility: raw record by checksum, rather than offset. The record
486 command optionally takes checksum which identifies certain record from
489 New facility: per field ranking. Rank may be given as M [F N] where
490 M is default rank and N is rank for CCL terms from field F.
492 --- 1.6.14 2012/06/04
494 Fix for IE7/8 in pz.js
496 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
498 Lower log level some places.
500 Remove some invalid test results.
502 --- 1.6.13 2012/05/23
504 Introducing a version=2 parameter for show, termlist and bytarget commands.
505 This enables pazpar2 to return approximation on hit and count count when
506 doing record filtering using the limit parameter on search and a
507 limitmap with a value of "local:"
509 Setting pz:xslt may embed local XSLT as an alternative to referring
511 Value is not CDATA but XML nodes embedded, so escaping is not necessary
512 but a root element *must* be present. For example:
513 <settings target="target="z3950.indexdata.com/marc">
522 Metadata field rank may given by XML internal document (pz:xslt
523 result). If rank is not given, the rank from service description is
526 Metadata field can now configured a default limitmap and facetmap.
527 Setting limitmap to "local:" would work for all kind of targets, but would
528 prob. not be the optimal solution. But at least better than the default behavior
529 of pazpar2 where no filtering is done.
531 A service definition can now also contains <set/> that defines service-wide
532 settings. These will override server-wide sets and will be overridded by
535 New setting, pz:present_chunk, that specifies number of records to fetch
536 at a time. Zero will disable chunkation; will fetch max_records at once.
538 --- 1.6.12 2012/03/14
540 Revert the format change in termlist response, that could break
541 some clients / UIs since they were expecting an (empty) element
542 if no facet values was found.
544 --- 1.6.11 2012/03/07
546 Revert the behavior of returning errors when unable to block
547 on termlist, bytarget and search, when unable to block due to
548 other block. The client will now receive a regular response,
549 but it will be logged in the server. A parameter (report) is
550 added to change behavior to return error response or WARNING
551 status message. Consider this "API" as private, as it is mostly
552 untested and could be changed in future releases.
554 Fix spell error in pz2.js fix in 1.6.10.
556 New Marc2TurboMarc.xsl (contribution from Sven Porst).
557 Can solve the missing marc21.xsl updates in some cases.
559 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
560 substring (contribtion from Sven Porst)
562 marc21.xsl: fix 1-based substring call
564 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
566 Add test_termlist_block to test suite
568 --- 1.6.10 2012/02/23
570 Fix SEGV for invalid PQFs and SRU/SOLR targets
571 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
573 Fix pz2.js: "null object" due to change in in bytarget result XML.
575 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
576 Added this normalization to the other subject-long fields (d6xx),
577 where it was missing.
579 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
580 Still differences around medium and holdings. marc21.xsl is not
581 longer active used by Index Data, and should be considered unsupported.
582 Use tmarc.xsl instead.
586 Fix SEGV that could occur for failed connections.
590 Fix bug for command sort that could return no results for active clients
591 (from previous search). This bug was present in 1.6.6-1.6.7.
593 Fix bug in results that could include results that should have been
594 filtered out. This bug was present in 1.6.6-1.6.7.
598 Fix bug introduced in 1.6.6 where a connection re-use could stall
601 Local filtering may now specify a local metadata field, eg.
602 pz:limitmap:somefield[t]=local:otherfield
606 For search, when limit and or filtering is in place and search
607 is identical to previous search, the result set is re-used and the
608 target is not searched.
610 Limits may work perform local filtering as well, by using "local:"
615 Updated bytarget command to contain a suggestions element with misspelled
616 words and suggestions to these. pz2.js has been updated to deliver this
617 onwards as well. Only target that currently delivers this is the solr
618 client in YAZ 4.2.18.
622 New service definition element, xslt, that allows an embedded stylesheet
623 to be defined. This can be referred to from pz:xslt as an alternative to
626 New pz:sortmap:field setting for specifying hints on how to make
627 a target natively sort on a field. This is used for command=show in
628 conjunction with sort.
630 New pz:url setting for specifying the actual URL for a target. When
631 this is used the target ID is not used as URL anymore and the target ID
632 may be almost any string (not including []).
634 command=termlist without name parameter returns all termlists/facets.
635 Previously if name parameter was omitted, only "subject" was returned.
639 Make termlist sorting stable. Terms with same frequency are now sorted by
640 their display name. This makes a pretty display and improves our
641 regression test because qsort is not a stable sort.
643 New sort parameter value 'position'. The 'position' sorts merged records
644 by their original position from the remote target. This is primarily useful
645 for debugging and may be used for targets that already perform some kind
646 of relevance ranking. Note that sort by default is decreasing; so to get
647 records in their original order sort=position:1 must be used.
651 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
653 Facility to change working directory for pazpar2 daemon. Option -wdir
654 sets working directory to dir. This facility is useful if core dumps
655 must be saved. In this case, the current working directory must be
656 writable by the running user, such as "nobody".
660 New configuration element <icu_chain> for <server>/<service> which
661 allows a named ICU rule (chain) to be defined. The names relevance,
662 sort, mergekey and facet are used for those operations. The definition
663 <icu_chain id="sort" locale="en"> .. </icu_chain>
665 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
666 And so on.. for relevance, mergekey and facet as well. The latter
667 style is deprecated. The facet terms are normalized by the facet
668 rule by default. This may be changed on a metadata field basis by
669 defining the new attribute 'facetrule' for the metadata element.
671 <icu_chain id="myrule" locale="en"> ... </icu_chain>
672 <metadata name="author" termlist="yes" facetrule="myrule"/>
674 Preserve rorder for merged metadata. Fixes issue as reported by Sven
675 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
677 tmarc.xsl: set journal-subpart to 773$ only.
681 Modify the behavior for the limit parameter (first defined in 1.5.7).
682 Mapping of limit searches are now defined by the new configuration item
683 pz:limitmap. Fix a dead-lock problem with the limit parameter.
685 Extend tmarc.xsl to extract 773$g data (OpenURL).
689 ICU default maps remove backquote (`).
691 Command 'search' takes limit parameter (optional). The limit parameter
692 allows a search to be limited one or more facets and the corresponding
693 values. This is for server side filtering.
695 Configure tweak: Use -lm for log(3) if needed
699 Fix a problem with skiparticle sortkey that could be completely
700 ignored (and reduced to "").
702 Fix dependency problem in pazpar2 RPM package (did not require
703 libyaz4 as it should).
707 Fix memory leak that occurred for command=termlist&name=xtargets .
709 Pazpar2 may save HTTP requests. Enabled by option -R.
713 Experimental support for DTIC DADS target. New dads-pz2.xsl.
715 Support for query_syntax (overrides the default for SRU | Z39.50)
717 Support for extraArgs (ZOOM "extraArgs" option) for targets
719 New commands: status-server and status-session
723 Fix for threaded runs: Client now have a copy of the database URL,
724 which can used after the database has been release from the client.
725 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
727 tmarc.xsl: Add journal-title-abbrev and full text.
729 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
731 Fix for cmd=record before search.
733 Session Logging clean up.
735 Fix wrong termlist factor when maxrecs is different from 100.
739 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
740 Term factor is default enabled but can be diseabled by
741 pz:termlist_term_factor=0
745 Add scaling of facet count. Currently always enabled, needs fixing.
746 Allow user-defined info for target suffix. This has no meaning in
747 Pazpar2 except to distinguish targets from each other. The suffix
748 data begins with #. For example z3950.indexdata.com/gils#Mydata
750 Added exact-match recordfilter; format name=value
754 SOLR support. Pazpar2 may operate as web service client for SOLR.
758 Fix for show command and block=1 (dead lock). Bug was introduced in
763 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
764 tested on CentOS 5.5 only.
768 Fix problem with result sets being removed from a client session
769 if the connection for it was resused by another session. Bug #3489.
771 New iphone UI for Pazpar2 (www/iphone).
775 Fixes for threaded operation.
777 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
779 New example services in etc/services in source. In the Debian packages
780 these are located in /etc/pazpar2/services-available
782 Threaded mode operational on Windows. Requires Windows 7 or Windows
785 Default value of setting pz:max_connections is 0 which means that there
786 is no limit on number of connections.
790 Pazpar2 may operate in threaded mode. Enabled by element threads in
791 the configuration. See pazpar2_conf for details.
793 New setting setting: pz:max_connections. Setting pz:max_connections is
794 a limit of number of sockets to a host. When this limit is reached,
795 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
796 The client will be marked Client_Error when it can not be searched
797 (other clients in a session may work). If pz:max_connections is not set
798 for a target, a value of 30 will be used. Note: the pz:max_connections
799 will only work in threaded mode.
801 pz2.js: JSON support for show.
803 Debian package: Enable default service, default.xml, before starting
804 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
808 Debian version depends on on libyaz4. Note that Pazpar2 will still
809 compile from source with YAZ 3.
811 Split services into separate files. The example configuration file
812 pazpar2.cfg.dist now includes a default service default.xml (part of
813 etc). And default.xml includes settings/edu.xml. The default.xml file,
814 not to be confused with settings/defaults.xml, is a template for jsdemo
815 and other services. The Debian package installs /etc/pazpar2/server.xml
816 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
817 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
818 The default.xml (from etc) is installed in /etc/pazpar2/services-available
819 and a symlink to it is created from services-enabled. The default.xml
820 service is unnamed and, thus, will be used by jsdemo and test1.
822 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
823 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
827 Support for additional fields in cf.xsl and pazpar2.conf.dist:
828 publisher, available, due, location (=locallocation), callno
829 (=callnumber), thumburl and score.
831 Describe pz:xslt and the auto setting.
833 Move mergekey definition away from the normalization stylesheets and
834 define a mergekey common for all target types in pazpar2.cfg.
836 Code update: Use the Odr_int type for hit counts. This is part of
837 YAZ 3.0.47 and later and so configure checks for that.
841 Metadata attribute 'skiparticle' also works for ICU based
842 normalization. (was only working for the non-ICU/ASCII before).
844 Command bytarget with argument settings=1 will show settings per
845 target.. This is to be able to verify correct settings and be able to
846 test that they are correct. The database settings array size is now
847 also stored.. Problems with database settings array is that if not
848 careful it will be too small (smaller than dictionary per-service
851 Make record list sorting stable by comparing mergekey for records if
852 relevance/title or other sorting criteria all match. This is merely to
853 ensure that our regressions tests works (reproducible output).
855 Relevance calculation changes: use a different denominator (length) for
856 per-field relevance scoring.. Instead of length of all ranked fields we
857 now use length of individual fields (as if they were individual "free"
858 text fields). This will ensure that documents with a long field with no
859 match (say description) will not "hurt" a title match.
861 Diagnostic member was not set on connection error. Fixed
865 Command search takes two optional parameters, startecs and maxrecs,
866 that specifies the start offset (0, 1, ...) and maximum number of records
867 to fetch for each target.
869 XSLTs + MARC maps are cached within a session so we don't re-parse
870 them over and over again. Even for a session with a single search
871 there's much to be gained because many targets use the same
874 The metadata attribute 'mergekey' now takes one of three values 'no',
875 'required', 'optional' . And the resulting mergekey from metadata
876 is now ordered in the same way as metadata in the service definition.
877 Older Pazpar2 version use the order in which metadata appeared in a
880 The search argument 'filter' now offers a new operator ~ which does a
881 substring match. The = operator works as before: string match for
882 anything but pz:id, or target match for pz:id.
884 New setting pz:recordfilter. The value of this setting takes the
885 form name[~value]. This setting makes Pazpar2 ignore all retrieved
886 records that do not have the metadata element name with value substring
889 Pazpar2 allows YAZ log level to be set (option -v).
893 For WS responses Pazpar2 creates XML header. Exception: raw record.
895 Setting XML files are now stored in etc/settings instead of etc. This
896 reflects the layout with the Debian package layout.
898 Settings may be posted for command=settings. The POSTed settings must
899 have root element 'settings' like regular setting files. In order to be
900 recognized, the POST request must use Content-Type=text/xml.
902 A service may be posted for command=init. This service will be used
903 during the session. The service may have its own target settings,
904 ICU config, timeout, etc. In order to be recognized, the POST request
905 must use Content-Type=text/xml.
907 Timeout values may be given per-service. That's element 'timeout'
908 which takes three attribute values (a subset may be given): 'session',
909 'z3950_operation', 'z3950_session'. Option -T is no longer supported
910 - used to specify session timeout.
912 Option -t tests the Pazpar2 configuration and returns exit code
913 (0=success, non-zero=failure). In previous version of Pazpar2, -t
914 specified local settings.
916 In version 1.2.0 the configuration file - after include processing -
917 was dumped to stdout. Now, the configuration is only dumped to the
918 yaz log file if option -d is given.
922 Configuration may now have multiple server areas. This means that a
923 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
924 yet supported - on a server basis. Configuration may also have multiple
925 services .. That is repeating service elements inside a server. Each
926 has an attribute 'id' which serves as service ID. This ID in turn may
927 be used in a Pazpar2 session, by specifying parameter service=ID for
928 command init. There can be at most one unnamed service inside a server
929 which can be referred to by not specifying an service ID for command
930 init (backwards compatible). In order to partition multiple servers and
931 services a new include directive has been added. This takes an attribute
932 'src' which specifies one or more sub-files. For example to include
933 service files, one might use:
934 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
935 It is the intention that that completely makes the settings directive
938 Fix problem where the record command would wait forever if there were
939 no targets to wait for (activeclients == 0).
943 One result set is created per session (last search) rather than for
944 each connection which happen to be shared (bug #3009).
946 marc21 stylesheets changed for efficiency.
950 Session timeout may be specified on the command-line as option -T.
952 Pazpar2 may now be operated in a no-merged mode for records.. All records
953 will be considered unique. This mode is enabled if no mergekey is
954 generated by the normalization stylesheet (pz:xslt).
956 Pazpar2 caches original records from each target and the 'record' command
957 with offset returns the original record if 'syntax' and 'esn' are NOT
958 specified. This speeds up retrieval of original records but also means
959 that Pazpar2 uses more memory. The cached records will be freed when the
960 session terminates or a new search is executed.
962 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
963 library part of YAZ is used.
965 Added SRU client support.
967 Automatically computes pz:nativesyntax if not provided. Works for XML and
970 --- 1.0.13 2008/11/24

986 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
990 Changed the JS library pz2.js to use POST for long URL (+ params).
992 Added installation instructions for Windows. Note: NT services is
993 NOT available until we make a new release of YAZ.
995 Preserve order of repeated metadata fields (they were reversed before).
997 More MARC21 information extracted for metadata.
1001 Fixed bug #1162: HTML entities are not escaped properly.
1003 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
1005 --- 1.0.7 2008/04/14
1007 Marc21 stylesheet updated to reflect multiple full text fields
1009 --- 1.0.6 2008/03/12
1011 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1013 Fixed bug 2100: Database wildcards not working
1015 --- 1.0.5 2007/11/09
1017 Added support for retrieval of records in binary.
1019 Fixed bug 1794: Pazpar2 does not return valid XML.
1021 Deal with ICU not returning sortkey (resulted in SEGV before).
1023 --- 1.0.4 2007/09/28
1025 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1026 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1028 Improved diagnostics when Pazpar2 HTTP decoding fails.
1030 Pazpar2 requests may be POSTed as using Content-Type
1031 application/x-www-form-urlencoded.
1033 Pazpar2 honors LF in HTTP headers.
1035 Handle targets that handle negative hit counts (should not happen, but it
1038 --- 1.0.3 2007/09/19
1040 ICU is used for tokenization and normalization of the following: mergekey,
1041 sorting, relevance terms.
1043 Debian package now enables ICU tokenization and normalization by default.
1045 --- 1.0.2 2007/08/22
1047 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1048 ways: Either as parameters to the normalization stylesheets (which would allow the
1049 programmer to postprocess or use the values in any way) or after the normalization
1050 step, in which case values are made part of the normalized record (and available for
1051 sorting, termlists, display, or other interface-related use.
1053 Implemented sorting by year.
1055 Option -d dumps records to the current log file instead of stderr.
1057 Fixes for compilation on cygwin.
1059 Z39.50 client code uses pz:elements. pz:elements was recognized in
1060 earlier Pazpar2 versions but it was not used for anything.
1062 icu_chain_test is using fgets instead of getline - fixes compilation
1065 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1066 query conversions fail (rather than _any_). This means targets that do
1067 not support some fields are ignored in a search.
1069 --- 1.0.1 2007/07/03
1071 Improved handling of socket timeout for Z39.50 connections.
1073 Misc documentation updates and spell fixes.
1075 Debian package pazpar2 creates log rotate entry.
1077 Debian package pazpar2-apache2 reloads Apache2.
1079 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1082 --- 1.0.0 2007/06/20
1084 First public release.
