57 Fix typos is sortmap documentation.
59 Doc: fix misplaced variablelist tag.
63 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
64 It's been like that since version 1.1.1 from August 2009.
66 Add support for result-set caching via memcached. See description of
67 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
69 Add support for a <metadata> container tag. Patfh from Sven Porst.
71 Add support for XInclude in main configuarion file. Patch from Sven Porst.

127 Fix issue with hanging show/bytarget. Could happen if new search was
128 fired with filter before show from previous show completed.
130 Add 'date' handling for solr-pz2.xsl.
132 --- 1.6.33 2013/08/13
134 pz:authentication may carry user group password. If pz:authentication
135 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
136 authentication. Two forms are allowed
139 If no blanks are present, open authentication is in use (as before).
141 Fix {prev,next}recid elements that are returned by record
142 command. These were incorrect in versions 1.6.23 thru 1.6.32.
144 --- 1.6.32 2013/06/14
146 Experimental support for snippets. If argument snippets=1 is given
147 for command record or show, the text will include <match>-tags for
148 those area that matches.
150 Fix memory leak WRT client structures (incorrect inc ref count).
152 Log when a HTTP response is serialized and the time elapsed.
154 New command, service, which returns current service XML in use for
157 --- 1.6.31 2013/05/24
159 Local limit for fields of type "generic" (ie text fields) are
160 now normalized by mergekey rule before comparison takes place.
161 Before, no normalization took place and comparsion was, thus, exact.
163 New facility: dynamic rank , which allows ranking to be changed
164 for an existing result set. The rank can be set for search or
165 show. This overrides the rank for metadata elements (which fields
168 New facility:dynamic mergekey , which allows mergekey to be changed
169 for an existing result set. The mergekey can be set for search or
172 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
173 Also, allow ports to be given as names (not just integers).
174 Fix @-notation on systems that don't support IPV6 sockets.
176 --- 1.6.30 2013/04/26
178 Add MasterKey Connect configuration. Refer to section "non-standard
179 databases" for more information.
181 Allow timeformat for log to be specified with option -m (as Metaproxy
184 New Debian package pazpar2-dbg.
186 Fix NULL ptr reference of se->relevance. If a new search is initiated
187 and a CCL query fails to parse, Pazpar2 could crash.
189 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
190 existed in 1.6.29 only.
192 --- 1.6.29 2013/04/05
194 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
195 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
196 changed by setting "host" attribute for the "listen" element.
198 Change semantics of pz:extendrecs. Allow for repeated fetches .
199 pz:extendrecs is now the number of extra records to fetch (was total
202 --- 1.6.28 2013/03/21
204 Fix hang or memory violation if show occurred before a search. (not that
205 it makes much sense to perform a show before a search).
207 --- 1.6.27 2013/03/08
209 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
212 --- 1.6.26 2013/03/08
214 New pz:metadata attribute, empty="empty-value" for Pazpar2's
215 internal representation. With this attribute, Pazpar2 treates an empty
216 pz:metadata type as having the value for "empty" - if empty.
218 New setting, pz:extendrecs, which triggers extended fetch of records
219 for a database beyond pz:maxrecs for a show command.
221 Fix warning that was falsely issued for "missing limitmap".
223 Log message for Pazpart start/stop changed. Now using same style as
224 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
226 --- 1.6.25 2013/02/07
228 Fix hang of 2nd command=show with esn/syntax given.
230 --- 1.6.24 2013/01/18
232 New merge attribute type: 'first', which takes all metadata fields
233 from first target that returns the particular field.
235 --- 1.6.23 2013/01/02
237 Extend info command with hostname and YAZ SHA1
238 Indent results for both command stat and info.
240 Allow limit on merged content. The new configuration metadata
241 element, limitcluster, configures that a metadata element (name) be used
242 as limit name for search. Applies to the whole service (ie all targets),
243 unlike pz:limitmap which is configured per-target (database).
245 New feature: limitmap local:* matches against all metadata fields.
247 Allow repeated list in limitmap spec . Separated by comma. For
248 example: value="local:title,rpn:@attr 1=4".
250 New element <message> in bytarget response. Holds diagnostic message
251 of code (say 'Unsupported Use Attribute' for Bib-1 114).
253 Improved logging for record ingestion failures.
255 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
256 when YAZ is compiled without ICU support.
258 --- 1.6.22 2012/10/11
260 Requires YAZ-4.2.40 to support native solr support.
262 Fix and improve logic handling whether or not to re-do search on sort
263 order changes. A sort order with change in ascending/descending only
264 whould not trigger a new search, which is required for targets with
265 native sorting capabilities. Each client is now checked if instructions
266 (sortmap) exist for native sorting and only client that does requires
267 it is researched. Other clients is just re-ingesting the records,
268 they already have. The resultset is now cleared if any researching
271 Connection sharing between session has broken since version 1.6.8 with
272 introduction of logic that would minimize searching if pazpar2 could
273 detect this based on same query and limits and partly sort order.
274 This could lead to segementations violations.
276 Added a chapter in the manaul about relevance ranking.
278 --- 1.6.21 2012/09/24
280 Rank tweak: follow=number will increase mult by number if two terms
281 occur next to each other; number-1 if they are one term apart , .. 0
282 if they are number a part (all in order). Default is 0 (following
283 terms has no effect).
285 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
286 value given by lead and l is length from beginning of field where
287 term occurs (l=0 for first term, l=1 for second term, ..). Default
290 Rank tweak: length=strategy. length="linear" if mult is to be divided
291 by length (existing, default behavior), length="log" if mult is to be
292 divided by log2(1+length), length="none" if mult is not to be affected
295 --- 1.6.20 2012/09/21
297 Rank algorithm details may be printed as part of show response in
298 element <relevance_info>.. This is only printed if <rank debug="yes"/>
301 Record as returned by show/record command have a minimal indentation
302 which makes things human-readable.
304 New configuration of default sorting criteria (sort-default) in
305 service definition. If no criteria is defined it will be as before
308 Search command now supports sort parameter just as the show command.
309 If no parameter is give, it will use the service sort-default value.
311 --- 1.6.19 2012/09/18
313 Rank algorithm skips strings that gets normalized to empty string.
314 For example, & and ! could map to the empty string. The weight for
315 those terms is now 0 (as if they were not part of the query).
317 Rank algorithm does not use CCL from limitmap; only from the query
318 parameter (user query).
322 --- 1.6.18 2012/09/17
324 Rank algorithm configurable by 'rank' element inside service. So far
325 only, attribute 'cluster' is recognized. If cluster="yes", multiple
326 records inside a cluster boosts higher than single records. This
327 is default behavior and existing behavior. cluster="no" takes the
328 average score of each record in a cluster.
330 --- 1.6.17 2012/09/05
332 Fix bad re-use of connections (connections with changing proxy should not
335 --- 1.6.16 2012/08/22
337 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
338 resultset and sorting when the sort order is position. However this will be done on
339 every client poll, which will make pazpar2 continuing reset and fetching.
340 It should only be done on FIRST request where the sort order change.
342 Fix an issue on suggestion option: Also disable suggestions on empty string.
344 Clean up in turbo marc stylesheet.
346 Remove the hardcoded size of termlists.
348 --- 1.6.15 2012/06/27
350 New facility: ccldirective may be given in service definition. Allows
351 CCL parsing to be customized a bit, such as defining names of operators
354 New facility: raw record by checksum, rather than offset. The record
355 command optionally takes checksum which identifies certain record from
358 New facility: per field ranking. Rank may be given as M [F N] where
359 M is default rank and N is rank for CCL terms from field F.
361 --- 1.6.14 2012/06/04
363 Fix for IE7/8 in pz.js
365 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
367 Lower log level some places.
369 Remove some invalid test results.
371 --- 1.6.13 2012/05/23
373 Introducing a version=2 parameter for show, termlist and bytarget commands.
374 This enables pazpar2 to return approximation on hit and count count when
375 doing record filtering using the limit parameter on search and a
376 limitmap with a value of "local:"
378 Setting pz:xslt may embed local XSLT as an alternative to referring
380 Value is not CDATA but XML nodes embedded, so escaping is not necessary
381 but a root element *must* be present. For example:
382 <settings target="target="z3950.indexdata.com/marc">
391 Metadata field rank may given by XML internal document (pz:xslt
392 result). If rank is not given, the rank from service description is
395 Metadata field can now configured a default limitmap and facetmap.
396 Setting limitmap to "local:" would work for all kind of targets, but would
397 prob. not be the optimal solution. But at least better than the default behavior
398 of pazpar2 where no filtering is done.
400 A service definition can now also contains <set/> that defines service-wide
401 settings. These will override server-wide sets and will be overridded by
404 New setting, pz:present_chunk, that specifies number of records to fetch
405 at a time. Zero will disable chunkation; will fetch max_records at once.
407 --- 1.6.12 2012/03/14
409 Revert the format change in termlist response, that could break
410 some clients / UIs since they were expecting an (empty) element
411 if no facet values was found.
413 --- 1.6.11 2012/03/07
415 Revert the behavior of returning errors when unable to block
416 on termlist, bytarget and search, when unable to block due to
417 other block. The client will now receive a regular response,
418 but it will be logged in the server. A parameter (report) is
419 added to change behavior to return error response or WARNING
420 status message. Consider this "API" as private, as it is mostly
421 untested and could be changed in future releases.
423 Fix spell error in pz2.js fix in 1.6.10.
425 New Marc2TurboMarc.xsl (contribution from Sven Porst).
426 Can solve the missing marc21.xsl updates in some cases.
428 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
429 substring (contribtion from Sven Porst)
431 marc21.xsl: fix 1-based substring call
433 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
435 Add test_termlist_block to test suite
437 --- 1.6.10 2012/02/23
439 Fix SEGV for invalid PQFs and SRU/SOLR targets
440 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
442 Fix pz2.js: "null object" due to change in in bytarget result XML.
444 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
445 Added this normalization to the other subject-long fields (d6xx),
446 where it was missing.
448 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
449 Still differences around medium and holdings. marc21.xsl is not
450 longer active used by Index Data, and should be considered unsupported.
451 Use tmarc.xsl instead.
455 Fix SEGV that could occur for failed connections.
459 Fix bug for command sort that could return no results for active clients
460 (from previous search). This bug was present in 1.6.6-1.6.7.
462 Fix bug in results that could include results that should have been
463 filtered out. This bug was present in 1.6.6-1.6.7.
467 Fix bug introduced in 1.6.6 where a connection re-use could stall
470 Local filtering may now specify a local metadata field, eg.
471 pz:limitmap:somefield[t]=local:otherfield
475 For search, when limit and or filtering is in place and search
476 is identical to previous search, the result set is re-used and the
477 target is not searched.
479 Limits may work perform local filtering as well, by using "local:"
484 Updated bytarget command to contain a suggestions element with misspelled
485 words and suggestions to these. pz2.js has been updated to deliver this
486 onwards as well. Only target that currently delivers this is the solr
487 client in YAZ 4.2.18.
491 New service definition element, xslt, that allows an embedded stylesheet
492 to be defined. This can be referred to from pz:xslt as an alternative to
495 New pz:sortmap:field setting for specifying hints on how to make
496 a target natively sort on a field. This is used for command=show in
497 conjunction with sort.
499 New pz:url setting for specifying the actual URL for a target. When
500 this is used the target ID is not used as URL anymore and the target ID
501 may be almost any string (not including []).
503 command=termlist without name parameter returns all termlists/facets.
504 Previously if name parameter was omitted, only "subject" was returned.
508 Make termlist sorting stable. Terms with same frequency are now sorted by
509 their display name. This makes a pretty display and improves our
510 regression test because qsort is not a stable sort.
512 New sort parameter value 'position'. The 'position' sorts merged records
513 by their original position from the remote target. This is primarily useful
514 for debugging and may be used for targets that already perform some kind
515 of relevance ranking. Note that sort by default is decreasing; so to get
516 records in their original order sort=position:1 must be used.
520 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
522 Facility to change working directory for pazpar2 daemon. Option -wdir
523 sets working directory to dir. This facility is useful if core dumps
524 must be saved. In this case, the current working directory must be
525 writable by the running user, such as "nobody".
529 New configuration element <icu_chain> for <server>/<service> which
530 allows a named ICU rule (chain) to be defined. The names relevance,
531 sort, mergekey and facet are used for those operations. The definition
532 <icu_chain id="sort" locale="en"> .. </icu_chain>
534 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
535 And so on.. for relevance, mergekey and facet as well. The latter
536 style is deprecated. The facet terms are normalized by the facet
537 rule by default. This may be changed on a metadata field basis by
538 defining the new attribute 'facetrule' for the metadata element.
540 <icu_chain id="myrule" locale="en"> ... </icu_chain>
541 <metadata name="author" termlist="yes" facetrule="myrule"/>
543 Preserve rorder for merged metadata. Fixes issue as reported by Sven
544 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
546 tmarc.xsl: set journal-subpart to 773$ only.
550 Modify the behavior for the limit parameter (first defined in 1.5.7).
551 Mapping of limit searches are now defined by the new configuration item
552 pz:limitmap. Fix a dead-lock problem with the limit parameter.
554 Extend tmarc.xsl to extract 773$g data (OpenURL).
558 ICU default maps remove backquote (`).
560 Command 'search' takes limit parameter (optional). The limit parameter
561 allows a search to be limited one or more facets and the corresponding
562 values. This is for server side filtering.
564 Configure tweak: Use -lm for log(3) if needed
568 Fix a problem with skiparticle sortkey that could be completely
569 ignored (and reduced to "").
571 Fix dependency problem in pazpar2 RPM package (did not require
572 libyaz4 as it should).
576 Fix memory leak that occurred for command=termlist&name=xtargets .
578 Pazpar2 may save HTTP requests. Enabled by option -R.
582 Experimental support for DTIC DADS target. New dads-pz2.xsl.
584 Support for query_syntax (overrides the default for SRU | Z39.50)
586 Support for extraArgs (ZOOM "extraArgs" option) for targets
588 New commands: status-server and status-session
592 Fix for threaded runs: Client now have a copy of the database URL,
593 which can used after the database has been release from the client.
594 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
596 tmarc.xsl: Add journal-title-abbrev and full text.
598 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
600 Fix for cmd=record before search.
602 Session Logging clean up.
604 Fix wrong termlist factor when maxrecs is different from 100.
608 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
609 Term factor is default enabled but can be diseabled by
610 pz:termlist_term_factor=0
614 Add scaling of facet count. Currently always enabled, needs fixing.
615 Allow user-defined info for target suffix. This has no meaning in
616 Pazpar2 except to distinguish targets from each other. The suffix
617 data begins with #. For example z3950.indexdata.com/gils#Mydata
619 Added exact-match recordfilter; format name=value
623 SOLR support. Pazpar2 may operate as web service client for SOLR.
627 Fix for show command and block=1 (dead lock). Bug was introduced in
632 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
633 tested on CentOS 5.5 only.
637 Fix problem with result sets being removed from a client session
638 if the connection for it was resused by another session. Bug #3489.
640 New iphone UI for Pazpar2 (www/iphone).
644 Fixes for threaded operation.
646 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
648 New example services in etc/services in source. In the Debian packages
649 these are located in /etc/pazpar2/services-available
651 Threaded mode operational on Windows. Requires Windows 7 or Windows
654 Default value of setting pz:max_connections is 0 which means that there
655 is no limit on number of connections.
659 Pazpar2 may operate in threaded mode. Enabled by element threads in
660 the configuration. See pazpar2_conf for details.
662 New setting setting: pz:max_connections. Setting pz:max_connections is
663 a limit of number of sockets to a host. When this limit is reached,
664 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
665 The client will be marked Client_Error when it can not be searched
666 (other clients in a session may work). If pz:max_connections is not set
667 for a target, a value of 30 will be used. Note: the pz:max_connections
668 will only work in threaded mode.
670 pz2.js: JSON support for show.
672 Debian package: Enable default service, default.xml, before starting
673 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
677 Debian version depends on on libyaz4. Note that Pazpar2 will still
678 compile from source with YAZ 3.
680 Split services into separate files. The example configuration file
681 pazpar2.cfg.dist now includes a default service default.xml (part of
682 etc). And default.xml includes settings/edu.xml. The default.xml file,
683 not to be confused with settings/defaults.xml, is a template for jsdemo
684 and other services. The Debian package installs /etc/pazpar2/server.xml
685 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
686 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
687 The default.xml (from etc) is installed in /etc/pazpar2/services-available
688 and a symlink to it is created from services-enabled. The default.xml
689 service is unnamed and, thus, will be used by jsdemo and test1.
691 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
692 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
696 Support for additional fields in cf.xsl and pazpar2.conf.dist:
697 publisher, available, due, location (=locallocation), callno
698 (=callnumber), thumburl and score.
700 Describe pz:xslt and the auto setting.
702 Move mergekey definition away from the normalization stylesheets and
703 define a mergekey common for all target types in pazpar2.cfg.
705 Code update: Use the Odr_int type for hit counts. This is part of
706 YAZ 3.0.47 and later and so configure checks for that.
710 Metadata attribute 'skiparticle' also works for ICU based
711 normalization. (was only working for the non-ICU/ASCII before).
713 Command bytarget with argument settings=1 will show settings per
714 target.. This is to be able to verify correct settings and be able to
715 test that they are correct. The database settings array size is now
716 also stored.. Problems with database settings array is that if not
717 careful it will be too small (smaller than dictionary per-service
720 Make record list sorting stable by comparing mergekey for records if
721 relevance/title or other sorting criteria all match. This is merely to
722 ensure that our regressions tests works (reproducible output).
724 Relevance calculation changes: use a different denominator (length) for
725 per-field relevance scoring.. Instead of length of all ranked fields we
726 now use length of individual fields (as if they were individual "free"
727 text fields). This will ensure that documents with a long field with no
728 match (say description) will not "hurt" a title match.
730 Diagnostic member was not set on connection error. Fixed
734 Command search takes two optional parameters, startecs and maxrecs,
735 that specifies the start offset (0, 1, ...) and maximum number of records
736 to fetch for each target.
738 XSLTs + MARC maps are cached within a session so we don't re-parse
739 them over and over again. Even for a session with a single search
740 there's much to be gained because many targets use the same
743 The metadata attribute 'mergekey' now takes one of three values 'no',
744 'required', 'optional' . And the resulting mergekey from metadata
745 is now ordered in the same way as metadata in the service definition.
746 Older Pazpar2 version use the order in which metadata appeared in a
749 The search argument 'filter' now offers a new operator ~ which does a
750 substring match. The = operator works as before: string match for
751 anything but pz:id, or target match for pz:id.
753 New setting pz:recordfilter. The value of this setting takes the
754 form name[~value]. This setting makes Pazpar2 ignore all retrieved
755 records that do not have the metadata element name with value substring
758 Pazpar2 allows YAZ log level to be set (option -v).
762 For WS responses Pazpar2 creates XML header. Exception: raw record.
764 Setting XML files are now stored in etc/settings instead of etc. This
765 reflects the layout with the Debian package layout.
767 Settings may be posted for command=settings. The POSTed settings must
768 have root element 'settings' like regular setting files. In order to be
769 recognized, the POST request must use Content-Type=text/xml.
771 A service may be posted for command=init. This service will be used
772 during the session. The service may have its own target settings,
773 ICU config, timeout, etc. In order to be recognized, the POST request
774 must use Content-Type=text/xml.
776 Timeout values may be given per-service. That's element 'timeout'
777 which takes three attribute values (a subset may be given): 'session',
778 'z3950_operation', 'z3950_session'. Option -T is no longer supported
779 - used to specify session timeout.
781 Option -t tests the Pazpar2 configuration and returns exit code
782 (0=success, non-zero=failure). In previous version of Pazpar2, -t
783 specified local settings.
785 In version 1.2.0 the configuration file - after include processing -
786 was dumped to stdout. Now, the configuration is only dumped to the
787 yaz log file if option -d is given.
791 Configuration may now have multiple server areas. This means that a
792 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
793 yet supported - on a server basis. Configuration may also have multiple
794 services .. That is repeating service elements inside a server. Each
795 has an attribute 'id' which serves as service ID. This ID in turn may
796 be used in a Pazpar2 session, by specifying parameter service=ID for
797 command init. There can be at most one unnamed service inside a server
798 which can be referred to by not specifying an service ID for command
799 init (backwards compatible). In order to partition multiple servers and
800 services a new include directive has been added. This takes an attribute
801 'src' which specifies one or more sub-files. For example to include
802 service files, one might use:
803 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
804 It is the intention that that completely makes the settings directive
807 Fix problem where the record command would wait forever if there were
808 no targets to wait for (activeclients == 0).
812 One result set is created per session (last search) rather than for
813 each connection which happen to be shared (bug #3009).
815 marc21 stylesheets changed for efficiency.
819 Session timeout may be specified on the command-line as option -T.
821 Pazpar2 may now be operated in a no-merged mode for records.. All records
822 will be considered unique. This mode is enabled if no mergekey is
823 generated by the normalization stylesheet (pz:xslt).
825 Pazpar2 caches original records from each target and the 'record' command
826 with offset returns the original record if 'syntax' and 'esn' are NOT
827 specified. This speeds up retrieval of original records but also means
828 that Pazpar2 uses more memory. The cached records will be freed when the
829 session terminates or a new search is executed.
831 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
832 library part of YAZ is used.
834 Added SRU client support.
836 Automatically computes pz:nativesyntax if not provided. Works for XML and
839 --- 1.0.13 2008/11/24
841 Command bytarget returns name of target (if defined).
843 --- 1.0.12 2008/11/04
845 Fixed bug #2021.. location now holds all brief elements.
847 --- 1.0.11 2008/10/15
849 Fixed check for application/x-www-form-urlencoded parameters.
851 --- 1.0.10 2008/10/14
853 Fixes for IE in pz2.js.
855 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
859 Changed the JS library pz2.js to use POST for long URL (+ params).
861 Added installation instructions for Windows. Note: NT services is
862 NOT available until we make a new release of YAZ.
864 Preserve order of repeated metadata fields (they were reversed before).
866 More MARC21 information extracted for metadata.
870 Fixed bug #1162: HTML entities are not escaped properly.
872 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
876 Marc21 stylesheet updated to reflect multiple full text fields
880 Fixed bug in pz2.js WRT DOMElement attributes on IE.
882 Fixed bug 2100: Database wildcards not working
886 Added support for retrieval of records in binary.
888 Fixed bug 1794: Pazpar2 does not return valid XML.
890 Deal with ICU not returning sortkey (resulted in SEGV before).
894 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
895 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
897 Improved diagnostics when Pazpar2 HTTP decoding fails.
899 Pazpar2 requests may be POSTed as using Content-Type
900 application/x-www-form-urlencoded.
902 Pazpar2 honors LF in HTTP headers.
904 Handle targets that handle negative hit counts (should not happen, but it
909 ICU is used for tokenization and normalization of the following: mergekey,
910 sorting, relevance terms.
912 Debian package now enables ICU tokenization and normalization by default.
916 Exposed user setting values (i.e. non-pz: names) to the record systems in two
917 ways: Either as parameters to the normalization stylesheets (which would allow the
918 programmer to postprocess or use the values in any way) or after the normalization
919 step, in which case values are made part of the normalized record (and available for
920 sorting, termlists, display, or other interface-related use.
922 Implemented sorting by year.
924 Option -d dumps records to the current log file instead of stderr.
926 Fixes for compilation on cygwin.
928 Z39.50 client code uses pz:elements. pz:elements was recognized in
929 earlier Pazpar2 versions but it was not used for anything.
931 icu_chain_test is using fgets instead of getline - fixes compilation
934 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
935 query conversions fail (rather than _any_). This means targets that do
936 not support some fields are ignored in a search.
940 Improved handling of socket timeout for Z39.50 connections.
942 Misc documentation updates and spell fixes.
944 Debian package pazpar2 creates log rotate entry.
946 Debian package pazpar2-apache2 reloads Apache2.
948 jsdemo included in distribution. It illustrates the use of the js/pz2.js
953 First public release.
