55 Package pazpar2-apache2 sets up everything WRT apache and only
56 package which requires it. pazpar2-apache depends on pazpar2-js.
60 Larger string buffer for forward address PAZ-987
61 Fixes buffer overflow that could occur if forward address is IPV6.
63 Updates to Windows NMAKE makefile for Visual Studio 2013.
67 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
68 include more details about the fault. Better install gdb and the
69 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
71 Per target timeout PAZ-981
72 New setting pz:timeout which overrides z3950_operation timeout
77 Re-introduce journal-subpart PAZ-980
78 Both citation and journal-subpart have same value.
82 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
85 Remove from js/pz2.js the code that translates just two diagnostic
86 codes (1 and 2) into human-readable messages. This is no longer
87 necessary at all, as PazPar2 has been returning the message as well as
88 the code in its responses since December 2012. Fixes PAZ-978.
90 primo xsl produces citation rather than journal-subpart PAZ-972

121 Log ingest failures and record failures:
123 Clean up logging PAZ-942
124 Use session lead in more places. Log hits/records/filtered for each
125 target when fetching is complete. Log hit count when a search
126 (response) is received. Remove some less useful log messages.
128 Fix warning about about missing (internal) stylesheet PAZ-956
130 Report number of filtered records in bytarget PAZ-954
132 Cache XML documents as they appear after normalization. The key
133 for the cache is database+record offset. Cache is removed if query
134 is modified for search. This speeds up re-establishing a result set
135 for databases where new query is same previous query.

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

263 Fix issue with hanging show/bytarget. Could happen if new search was
264 fired with filter before show from previous show completed.
266 Add 'date' handling for solr-pz2.xsl.
268 --- 1.6.33 2013/08/13
270 pz:authentication may carry user group password. If pz:authentication
271 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
272 authentication. Two forms are allowed
275 If no blanks are present, open authentication is in use (as before).
277 Fix {prev,next}recid elements that are returned by record
278 command. These were incorrect in versions 1.6.23 thru 1.6.32.
280 --- 1.6.32 2013/06/14
282 Experimental support for snippets. If argument snippets=1 is given
283 for command record or show, the text will include <match>-tags for
284 those area that matches.
286 Fix memory leak WRT client structures (incorrect inc ref count).
288 Log when a HTTP response is serialized and the time elapsed.
290 New command, service, which returns current service XML in use for
293 --- 1.6.31 2013/05/24
295 Local limit for fields of type "generic" (ie text fields) are
296 now normalized by mergekey rule before comparison takes place.
297 Before, no normalization took place and comparsion was, thus, exact.
299 New facility: dynamic rank , which allows ranking to be changed
300 for an existing result set. The rank can be set for search or
301 show. This overrides the rank for metadata elements (which fields
304 New facility:dynamic mergekey , which allows mergekey to be changed
305 for an existing result set. The mergekey can be set for search or
308 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
309 Also, allow ports to be given as names (not just integers).
310 Fix @-notation on systems that don't support IPV6 sockets.
312 --- 1.6.30 2013/04/26
314 Add MasterKey Connect configuration. Refer to section "non-standard
315 databases" for more information.
317 Allow timeformat for log to be specified with option -m (as Metaproxy
320 New Debian package pazpar2-dbg.
322 Fix NULL ptr reference of se->relevance. If a new search is initiated
323 and a CCL query fails to parse, Pazpar2 could crash.
325 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
326 existed in 1.6.29 only.
328 --- 1.6.29 2013/04/05
330 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
331 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
332 changed by setting "host" attribute for the "listen" element.
334 Change semantics of pz:extendrecs. Allow for repeated fetches .
335 pz:extendrecs is now the number of extra records to fetch (was total
338 --- 1.6.28 2013/03/21
340 Fix hang or memory violation if show occurred before a search. (not that
341 it makes much sense to perform a show before a search).
343 --- 1.6.27 2013/03/08
345 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
348 --- 1.6.26 2013/03/08
350 New pz:metadata attribute, empty="empty-value" for Pazpar2's
351 internal representation. With this attribute, Pazpar2 treates an empty
352 pz:metadata type as having the value for "empty" - if empty.
354 New setting, pz:extendrecs, which triggers extended fetch of records
355 for a database beyond pz:maxrecs for a show command.
357 Fix warning that was falsely issued for "missing limitmap".
359 Log message for Pazpart start/stop changed. Now using same style as
360 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
362 --- 1.6.25 2013/02/07
364 Fix hang of 2nd command=show with esn/syntax given.
366 --- 1.6.24 2013/01/18
368 New merge attribute type: 'first', which takes all metadata fields
369 from first target that returns the particular field.
371 --- 1.6.23 2013/01/02
373 Extend info command with hostname and YAZ SHA1
374 Indent results for both command stat and info.
376 Allow limit on merged content. The new configuration metadata
377 element, limitcluster, configures that a metadata element (name) be used
378 as limit name for search. Applies to the whole service (ie all targets),
379 unlike pz:limitmap which is configured per-target (database).
381 New feature: limitmap local:* matches against all metadata fields.
383 Allow repeated list in limitmap spec . Separated by comma. For
384 example: value="local:title,rpn:@attr 1=4".
386 New element <message> in bytarget response. Holds diagnostic message
387 of code (say 'Unsupported Use Attribute' for Bib-1 114).
389 Improved logging for record ingestion failures.
391 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
392 when YAZ is compiled without ICU support.
394 --- 1.6.22 2012/10/11
396 Requires YAZ-4.2.40 to support native solr support.
398 Fix and improve logic handling whether or not to re-do search on sort
399 order changes. A sort order with change in ascending/descending only
400 whould not trigger a new search, which is required for targets with
401 native sorting capabilities. Each client is now checked if instructions
402 (sortmap) exist for native sorting and only client that does requires
403 it is researched. Other clients is just re-ingesting the records,
404 they already have. The resultset is now cleared if any researching
407 Connection sharing between session has broken since version 1.6.8 with
408 introduction of logic that would minimize searching if pazpar2 could
409 detect this based on same query and limits and partly sort order.
410 This could lead to segementations violations.
412 Added a chapter in the manaul about relevance ranking.
414 --- 1.6.21 2012/09/24
416 Rank tweak: follow=number will increase mult by number if two terms
417 occur next to each other; number-1 if they are one term apart , .. 0
418 if they are number a part (all in order). Default is 0 (following
419 terms has no effect).
421 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
422 value given by lead and l is length from beginning of field where
423 term occurs (l=0 for first term, l=1 for second term, ..). Default
426 Rank tweak: length=strategy. length="linear" if mult is to be divided
427 by length (existing, default behavior), length="log" if mult is to be
428 divided by log2(1+length), length="none" if mult is not to be affected
431 --- 1.6.20 2012/09/21
433 Rank algorithm details may be printed as part of show response in
434 element <relevance_info>.. This is only printed if <rank debug="yes"/>
437 Record as returned by show/record command have a minimal indentation
438 which makes things human-readable.
440 New configuration of default sorting criteria (sort-default) in
441 service definition. If no criteria is defined it will be as before
444 Search command now supports sort parameter just as the show command.
445 If no parameter is give, it will use the service sort-default value.
447 --- 1.6.19 2012/09/18
449 Rank algorithm skips strings that gets normalized to empty string.
450 For example, & and ! could map to the empty string. The weight for
451 those terms is now 0 (as if they were not part of the query).
453 Rank algorithm does not use CCL from limitmap; only from the query
454 parameter (user query).
458 --- 1.6.18 2012/09/17
460 Rank algorithm configurable by 'rank' element inside service. So far
461 only, attribute 'cluster' is recognized. If cluster="yes", multiple
462 records inside a cluster boosts higher than single records. This
463 is default behavior and existing behavior. cluster="no" takes the
464 average score of each record in a cluster.
466 --- 1.6.17 2012/09/05
468 Fix bad re-use of connections (connections with changing proxy should not
471 --- 1.6.16 2012/08/22
473 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
474 resultset and sorting when the sort order is position. However this will be done on
475 every client poll, which will make pazpar2 continuing reset and fetching.
476 It should only be done on FIRST request where the sort order change.
478 Fix an issue on suggestion option: Also disable suggestions on empty string.
480 Clean up in turbo marc stylesheet.
482 Remove the hardcoded size of termlists.
484 --- 1.6.15 2012/06/27
486 New facility: ccldirective may be given in service definition. Allows
487 CCL parsing to be customized a bit, such as defining names of operators
490 New facility: raw record by checksum, rather than offset. The record
491 command optionally takes checksum which identifies certain record from
494 New facility: per field ranking. Rank may be given as M [F N] where
495 M is default rank and N is rank for CCL terms from field F.
497 --- 1.6.14 2012/06/04
499 Fix for IE7/8 in pz.js
501 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
503 Lower log level some places.
505 Remove some invalid test results.
507 --- 1.6.13 2012/05/23
509 Introducing a version=2 parameter for show, termlist and bytarget commands.
510 This enables pazpar2 to return approximation on hit and count count when
511 doing record filtering using the limit parameter on search and a
512 limitmap with a value of "local:"
514 Setting pz:xslt may embed local XSLT as an alternative to referring
516 Value is not CDATA but XML nodes embedded, so escaping is not necessary
517 but a root element *must* be present. For example:
518 <settings target="target="z3950.indexdata.com/marc">
527 Metadata field rank may given by XML internal document (pz:xslt
528 result). If rank is not given, the rank from service description is
531 Metadata field can now configured a default limitmap and facetmap.
532 Setting limitmap to "local:" would work for all kind of targets, but would
533 prob. not be the optimal solution. But at least better than the default behavior
534 of pazpar2 where no filtering is done.
536 A service definition can now also contains <set/> that defines service-wide
537 settings. These will override server-wide sets and will be overridded by
540 New setting, pz:present_chunk, that specifies number of records to fetch
541 at a time. Zero will disable chunkation; will fetch max_records at once.
543 --- 1.6.12 2012/03/14
545 Revert the format change in termlist response, that could break
546 some clients / UIs since they were expecting an (empty) element
547 if no facet values was found.
549 --- 1.6.11 2012/03/07
551 Revert the behavior of returning errors when unable to block
552 on termlist, bytarget and search, when unable to block due to
553 other block. The client will now receive a regular response,
554 but it will be logged in the server. A parameter (report) is
555 added to change behavior to return error response or WARNING
556 status message. Consider this "API" as private, as it is mostly
557 untested and could be changed in future releases.
559 Fix spell error in pz2.js fix in 1.6.10.
561 New Marc2TurboMarc.xsl (contribution from Sven Porst).
562 Can solve the missing marc21.xsl updates in some cases.
564 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
565 substring (contribtion from Sven Porst)
567 marc21.xsl: fix 1-based substring call
569 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
571 Add test_termlist_block to test suite
573 --- 1.6.10 2012/02/23
575 Fix SEGV for invalid PQFs and SRU/SOLR targets
576 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
578 Fix pz2.js: "null object" due to change in in bytarget result XML.
580 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
581 Added this normalization to the other subject-long fields (d6xx),
582 where it was missing.
584 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
585 Still differences around medium and holdings. marc21.xsl is not
586 longer active used by Index Data, and should be considered unsupported.
587 Use tmarc.xsl instead.
591 Fix SEGV that could occur for failed connections.
595 Fix bug for command sort that could return no results for active clients
596 (from previous search). This bug was present in 1.6.6-1.6.7.
598 Fix bug in results that could include results that should have been
599 filtered out. This bug was present in 1.6.6-1.6.7.
603 Fix bug introduced in 1.6.6 where a connection re-use could stall
606 Local filtering may now specify a local metadata field, eg.
607 pz:limitmap:somefield[t]=local:otherfield
611 For search, when limit and or filtering is in place and search
612 is identical to previous search, the result set is re-used and the
613 target is not searched.
615 Limits may work perform local filtering as well, by using "local:"
620 Updated bytarget command to contain a suggestions element with misspelled
621 words and suggestions to these. pz2.js has been updated to deliver this
622 onwards as well. Only target that currently delivers this is the solr
623 client in YAZ 4.2.18.
627 New service definition element, xslt, that allows an embedded stylesheet
628 to be defined. This can be referred to from pz:xslt as an alternative to
631 New pz:sortmap:field setting for specifying hints on how to make
632 a target natively sort on a field. This is used for command=show in
633 conjunction with sort.
635 New pz:url setting for specifying the actual URL for a target. When
636 this is used the target ID is not used as URL anymore and the target ID
637 may be almost any string (not including []).
639 command=termlist without name parameter returns all termlists/facets.
640 Previously if name parameter was omitted, only "subject" was returned.
644 Make termlist sorting stable. Terms with same frequency are now sorted by
645 their display name. This makes a pretty display and improves our
646 regression test because qsort is not a stable sort.
648 New sort parameter value 'position'. The 'position' sorts merged records
649 by their original position from the remote target. This is primarily useful
650 for debugging and may be used for targets that already perform some kind
651 of relevance ranking. Note that sort by default is decreasing; so to get
652 records in their original order sort=position:1 must be used.
656 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
658 Facility to change working directory for pazpar2 daemon. Option -wdir
659 sets working directory to dir. This facility is useful if core dumps
660 must be saved. In this case, the current working directory must be
661 writable by the running user, such as "nobody".
665 New configuration element <icu_chain> for <server>/<service> which
666 allows a named ICU rule (chain) to be defined. The names relevance,
667 sort, mergekey and facet are used for those operations. The definition
668 <icu_chain id="sort" locale="en"> .. </icu_chain>
670 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
671 And so on.. for relevance, mergekey and facet as well. The latter
672 style is deprecated. The facet terms are normalized by the facet
673 rule by default. This may be changed on a metadata field basis by
674 defining the new attribute 'facetrule' for the metadata element.
676 <icu_chain id="myrule" locale="en"> ... </icu_chain>
677 <metadata name="author" termlist="yes" facetrule="myrule"/>
679 Preserve rorder for merged metadata. Fixes issue as reported by Sven
680 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
682 tmarc.xsl: set journal-subpart to 773$ only.
686 Modify the behavior for the limit parameter (first defined in 1.5.7).
687 Mapping of limit searches are now defined by the new configuration item
688 pz:limitmap. Fix a dead-lock problem with the limit parameter.
690 Extend tmarc.xsl to extract 773$g data (OpenURL).
694 ICU default maps remove backquote (`).
696 Command 'search' takes limit parameter (optional). The limit parameter
697 allows a search to be limited one or more facets and the corresponding
698 values. This is for server side filtering.
700 Configure tweak: Use -lm for log(3) if needed
704 Fix a problem with skiparticle sortkey that could be completely
705 ignored (and reduced to "").
707 Fix dependency problem in pazpar2 RPM package (did not require
708 libyaz4 as it should).
712 Fix memory leak that occurred for command=termlist&name=xtargets .
714 Pazpar2 may save HTTP requests. Enabled by option -R.
718 Experimental support for DTIC DADS target. New dads-pz2.xsl.
720 Support for query_syntax (overrides the default for SRU | Z39.50)
722 Support for extraArgs (ZOOM "extraArgs" option) for targets
724 New commands: status-server and status-session
728 Fix for threaded runs: Client now have a copy of the database URL,
729 which can used after the database has been release from the client.
730 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
732 tmarc.xsl: Add journal-title-abbrev and full text.
734 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
736 Fix for cmd=record before search.
738 Session Logging clean up.
740 Fix wrong termlist factor when maxrecs is different from 100.
744 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
745 Term factor is default enabled but can be diseabled by
746 pz:termlist_term_factor=0
750 Add scaling of facet count. Currently always enabled, needs fixing.
751 Allow user-defined info for target suffix. This has no meaning in
752 Pazpar2 except to distinguish targets from each other. The suffix
753 data begins with #. For example z3950.indexdata.com/gils#Mydata
755 Added exact-match recordfilter; format name=value
759 SOLR support. Pazpar2 may operate as web service client for SOLR.
763 Fix for show command and block=1 (dead lock). Bug was introduced in
768 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
769 tested on CentOS 5.5 only.
773 Fix problem with result sets being removed from a client session
774 if the connection for it was resused by another session. Bug #3489.
776 New iphone UI for Pazpar2 (www/iphone).
780 Fixes for threaded operation.
782 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
784 New example services in etc/services in source. In the Debian packages
785 these are located in /etc/pazpar2/services-available
787 Threaded mode operational on Windows. Requires Windows 7 or Windows
790 Default value of setting pz:max_connections is 0 which means that there
791 is no limit on number of connections.
795 Pazpar2 may operate in threaded mode. Enabled by element threads in
796 the configuration. See pazpar2_conf for details.
798 New setting setting: pz:max_connections. Setting pz:max_connections is
799 a limit of number of sockets to a host. When this limit is reached,
800 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
801 The client will be marked Client_Error when it can not be searched
802 (other clients in a session may work). If pz:max_connections is not set
803 for a target, a value of 30 will be used. Note: the pz:max_connections
804 will only work in threaded mode.
806 pz2.js: JSON support for show.
808 Debian package: Enable default service, default.xml, before starting
809 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
813 Debian version depends on on libyaz4. Note that Pazpar2 will still
814 compile from source with YAZ 3.
816 Split services into separate files. The example configuration file
817 pazpar2.cfg.dist now includes a default service default.xml (part of
818 etc). And default.xml includes settings/edu.xml. The default.xml file,
819 not to be confused with settings/defaults.xml, is a template for jsdemo
820 and other services. The Debian package installs /etc/pazpar2/server.xml
821 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
822 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
823 The default.xml (from etc) is installed in /etc/pazpar2/services-available
824 and a symlink to it is created from services-enabled. The default.xml
825 service is unnamed and, thus, will be used by jsdemo and test1.
827 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
828 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
832 Support for additional fields in cf.xsl and pazpar2.conf.dist:
833 publisher, available, due, location (=locallocation), callno
834 (=callnumber), thumburl and score.
836 Describe pz:xslt and the auto setting.
838 Move mergekey definition away from the normalization stylesheets and
839 define a mergekey common for all target types in pazpar2.cfg.
841 Code update: Use the Odr_int type for hit counts. This is part of
842 YAZ 3.0.47 and later and so configure checks for that.
846 Metadata attribute 'skiparticle' also works for ICU based
847 normalization. (was only working for the non-ICU/ASCII before).
849 Command bytarget with argument settings=1 will show settings per
850 target.. This is to be able to verify correct settings and be able to
851 test that they are correct. The database settings array size is now
852 also stored.. Problems with database settings array is that if not
853 careful it will be too small (smaller than dictionary per-service
856 Make record list sorting stable by comparing mergekey for records if
857 relevance/title or other sorting criteria all match. This is merely to
858 ensure that our regressions tests works (reproducible output).
860 Relevance calculation changes: use a different denominator (length) for
861 per-field relevance scoring.. Instead of length of all ranked fields we
862 now use length of individual fields (as if they were individual "free"
863 text fields). This will ensure that documents with a long field with no
864 match (say description) will not "hurt" a title match.
866 Diagnostic member was not set on connection error. Fixed
870 Command search takes two optional parameters, startecs and maxrecs,
871 that specifies the start offset (0, 1, ...) and maximum number of records
872 to fetch for each target.
874 XSLTs + MARC maps are cached within a session so we don't re-parse
875 them over and over again. Even for a session with a single search
876 there's much to be gained because many targets use the same
879 The metadata attribute 'mergekey' now takes one of three values 'no',
880 'required', 'optional' . And the resulting mergekey from metadata
881 is now ordered in the same way as metadata in the service definition.
882 Older Pazpar2 version use the order in which metadata appeared in a
885 The search argument 'filter' now offers a new operator ~ which does a
886 substring match. The = operator works as before: string match for
887 anything but pz:id, or target match for pz:id.
889 New setting pz:recordfilter. The value of this setting takes the
890 form name[~value]. This setting makes Pazpar2 ignore all retrieved
891 records that do not have the metadata element name with value substring
894 Pazpar2 allows YAZ log level to be set (option -v).
898 For WS responses Pazpar2 creates XML header. Exception: raw record.
900 Setting XML files are now stored in etc/settings instead of etc. This
901 reflects the layout with the Debian package layout.
903 Settings may be posted for command=settings. The POSTed settings must
904 have root element 'settings' like regular setting files. In order to be
905 recognized, the POST request must use Content-Type=text/xml.
907 A service may be posted for command=init. This service will be used
908 during the session. The service may have its own target settings,
909 ICU config, timeout, etc. In order to be recognized, the POST request
910 must use Content-Type=text/xml.
912 Timeout values may be given per-service. That's element 'timeout'
913 which takes three attribute values (a subset may be given): 'session',
914 'z3950_operation', 'z3950_session'. Option -T is no longer supported
915 - used to specify session timeout.
917 Option -t tests the Pazpar2 configuration and returns exit code
918 (0=success, non-zero=failure). In previous version of Pazpar2, -t
919 specified local settings.
921 In version 1.2.0 the configuration file - after include processing -
922 was dumped to stdout. Now, the configuration is only dumped to the
923 yaz log file if option -d is given.
927 Configuration may now have multiple server areas. This means that a
928 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
929 yet supported - on a server basis. Configuration may also have multiple
930 services .. That is repeating service elements inside a server. Each
931 has an attribute 'id' which serves as service ID. This ID in turn may
932 be used in a Pazpar2 session, by specifying parameter service=ID for
933 command init. There can be at most one unnamed service inside a server
934 which can be referred to by not specifying an service ID for command
935 init (backwards compatible). In order to partition multiple servers and
936 services a new include directive has been added. This takes an attribute
937 'src' which specifies one or more sub-files. For example to include
938 service files, one might use:
939 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
940 It is the intention that that completely makes the settings directive
943 Fix problem where the record command would wait forever if there were
944 no targets to wait for (activeclients == 0).
948 One result set is created per session (last search) rather than for
949 each connection which happen to be shared (bug #3009).
951 marc21 stylesheets changed for efficiency.
955 Session timeout may be specified on the command-line as option -T.
957 Pazpar2 may now be operated in a no-merged mode for records.. All records
958 will be considered unique. This mode is enabled if no mergekey is
959 generated by the normalization stylesheet (pz:xslt).
961 Pazpar2 caches original records from each target and the 'record' command
962 with offset returns the original record if 'syntax' and 'esn' are NOT
963 specified. This speeds up retrieval of original records but also means
964 that Pazpar2 uses more memory. The cached records will be freed when the
965 session terminates or a new search is executed.
967 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
968 library part of YAZ is used.
970 Added SRU client support.
972 Automatically computes pz:nativesyntax if not provided. Works for XML and
975 --- 1.0.13 2008/11/24

991 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
995 Changed the JS library pz2.js to use POST for long URL (+ params).
997 Added installation instructions for Windows. Note: NT services is
998 NOT available until we make a new release of YAZ.
1000 Preserve order of repeated metadata fields (they were reversed before).
1002 More MARC21 information extracted for metadata.
1004 --- 1.0.8 2008/04/22
1006 Fixed bug #1162: HTML entities are not escaped properly.
1008 Native Windows port of Pazpar2. Makefile for Visual Studio provided.

1014 --- 1.0.6 2008/03/12
1016 Fixed bug in pz2.js WRT DOMElement attributes on IE.
1018 Fixed bug 2100: Database wildcards not working
1020 --- 1.0.5 2007/11/09
1022 Added support for retrieval of records in binary.
1024 Fixed bug 1794: Pazpar2 does not return valid XML.
1026 Deal with ICU not returning sortkey (resulted in SEGV before).
1028 --- 1.0.4 2007/09/28
1030 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1031 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1033 Improved diagnostics when Pazpar2 HTTP decoding fails.
1035 Pazpar2 requests may be POSTed as using Content-Type
1036 application/x-www-form-urlencoded.
1038 Pazpar2 honors LF in HTTP headers.
1040 Handle targets that handle negative hit counts (should not happen, but it
1043 --- 1.0.3 2007/09/19
1045 ICU is used for tokenization and normalization of the following: mergekey,
1046 sorting, relevance terms.
1048 Debian package now enables ICU tokenization and normalization by default.
1050 --- 1.0.2 2007/08/22
1052 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1053 ways: Either as parameters to the normalization stylesheets (which would allow the
1054 programmer to postprocess or use the values in any way) or after the normalization
1055 step, in which case values are made part of the normalized record (and available for
1056 sorting, termlists, display, or other interface-related use.
1058 Implemented sorting by year.
1060 Option -d dumps records to the current log file instead of stderr.
1062 Fixes for compilation on cygwin.
1064 Z39.50 client code uses pz:elements. pz:elements was recognized in
1065 earlier Pazpar2 versions but it was not used for anything.
1067 icu_chain_test is using fgets instead of getline - fixes compilation
1070 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1071 query conversions fail (rather than _any_). This means targets that do
1072 not support some fields are ignored in a search.
1074 --- 1.0.1 2007/07/03
1076 Improved handling of socket timeout for Z39.50 connections.
1078 Misc documentation updates and spell fixes.
