---- 1.0.0 2007/04/XX
+--- 1.4.4 2010/08/17
+
+Fix for show command and block=1 (dead lock). Bug was introduced in
+1.4.0.
+
+--- 1.4.3 2010/07/02
+
+New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
+tested on CentOS 5.5 only.
+
+--- 1.4.2 2010/06/18
+
+Fix problem with result sets being removed from a client session
+if the connection for it was resused by another session. Bug #3489.
+
+New iphone UI for Pazpar2 (www/iphone).
+
+--- 1.4.1 2010/05/21
+
+Fixes for threaded operation.
+
+New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
+
+New example services in etc/services in source. In the Debian packages
+these are located in /etc/pazpar2/services-available
+
+Threaded mode operational on Windows. Requires Windows 7 or Windows
+Server 2008.
+
+Default value of setting pz:max_connections is 0 which means that there
+is no limit on number of connections.
+
+--- 1.4.0 2010/03/29
+
+Pazpar2 may operate in threaded mode. Enabled by element threads in
+the configuration. See pazpar2_conf for details.
+
+New setting setting: pz:max_connections. Setting pz:max_connections is
+a limit of number of sockets to a host. When this limit is reached,
+Pazpar2 will wait up to 5 seconds for a connection to becomes available.
+The client will be marked Client_Error when it can not be searched
+(other clients in a session may work). If pz:max_connections is not set
+for a target, a value of 30 will be used. Note: the pz:max_connections
+will only work in threaded mode.
+
+pz2.js: JSON support for show.
+
+Debian package: Enable default service, default.xml, before starting
+Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
+
+--- 1.3.0 2010/01/25
+
+Debian version depends on on libyaz4. Note that Pazpar2 will still
+compile from source with YAZ 3.
+
+Split services into separate files. The example configuration file
+pazpar2.cfg.dist now includes a default service default.xml (part of
+etc). And default.xml includes settings/edu.xml. The default.xml file,
+not to be confused with settings/defaults.xml, is a template for jsdemo
+and other services. The Debian package installs /etc/pazpar2/server.xml
+which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
+server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
+The default.xml (from etc) is installed in /etc/pazpar2/services-available
+and a symlink to it is created from services-enabled. The default.xml
+service is unnamed and, thus, will be used by jsdemo and test1.
+
+New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
+new setting pz:negotiation_charset specifies character set for Z39.50 Init.
+
+--- 1.2.4 2010/01/15
+
+Support for additional fields in cf.xsl and pazpar2.conf.dist:
+publisher, available, due, location (=locallocation), callno
+(=callnumber), thumburl and score.
+
+Describe pz:xslt and the auto setting.
+
+Move mergekey definition away from the normalization stylesheets and
+define a mergekey common for all target types in pazpar2.cfg.
+
+Code update: Use the Odr_int type for hit counts. This is part of
+YAZ 3.0.47 and later and so configure checks for that.
+
+--- 1.2.3 2009/11/24
+
+Metadata attribute 'skiparticle' also works for ICU based
+normalization. (was only working for the non-ICU/ASCII before).
+
+Command bytarget with argument settings=1 will show settings per
+target.. This is to be able to verify correct settings and be able to
+test that they are correct. The database settings array size is now
+also stored.. Problems with database settings array is that if not
+careful it will be too small (smaller than dictionary per-service
+in settings).
+
+Make record list sorting stable by comparing mergekey for records if
+relevance/title or other sorting criteria all match. This is merely to
+ensure that our regressions tests works (reproducible output).
+
+Relevance calculation changes: use a different denominator (length) for
+per-field relevance scoring.. Instead of length of all ranked fields we
+now use length of individual fields (as if they were individual "free"
+text fields). This will ensure that documents with a long field with no
+match (say description) will not "hurt" a title match.
+
+Diagnostic member was not set on connection error. Fixed
+
+--- 1.2.2 2009/10/13
+
+Command search takes two optional parameters, startecs and maxrecs,
+that specifies the start offset (0, 1, ...) and maximum number of records
+to fetch for each target.
+
+XSLTs + MARC maps are cached within a session so we don't re-parse
+them over and over again. Even for a session with a single search
+there's much to be gained because many targets use the same
+transformation.
+
+The metadata attribute 'mergekey' now takes one of three values 'no',
+'required', 'optional' . And the resulting mergekey from metadata
+is now ordered in the same way as metadata in the service definition.
+Older Pazpar2 version use the order in which metadata appeared in a
+record instance.
+
+The search argument 'filter' now offers a new operator ~ which does a
+substring match. The = operator works as before: string match for
+anything but pz:id, or target match for pz:id.
+
+New setting pz:recordfilter. The value of this setting takes the
+form name[~value]. This setting makes Pazpar2 ignore all retrieved
+records that do not have the metadata element name with value substring
+(if given).
+
+Pazpar2 allows YAZ log level to be set (option -v).
+
+--- 1.2.1 2009/10/05
+
+For WS responses Pazpar2 creates XML header. Exception: raw record.
+
+Setting XML files are now stored in etc/settings instead of etc. This
+reflects the layout with the Debian package layout.
+
+Settings may be posted for command=settings. The POSTed settings must
+have root element 'settings' like regular setting files. In order to be
+recognized, the POST request must use Content-Type=text/xml.
+
+A service may be posted for command=init. This service will be used
+during the session. The service may have its own target settings,
+ICU config, timeout, etc. In order to be recognized, the POST request
+must use Content-Type=text/xml.
+
+Timeout values may be given per-service. That's element 'timeout'
+which takes three attribute values (a subset may be given): 'session',
+'z3950_operation', 'z3950_session'. Option -T is no longer supported
+- used to specify session timeout.
+
+Option -t tests the Pazpar2 configuration and returns exit code
+(0=success, non-zero=failure). In previous version of Pazpar2, -t
+specified local settings.
+
+In version 1.2.0 the configuration file - after include processing -
+was dumped to stdout. Now, the configuration is only dumped to the
+yaz log file if option -d is given.
+
+--- 1.2.0 2009/09/10
+
+Configuration may now have multiple server areas. This means that a
+Pazpar2 instance may listen on multiple ports. Virtual hosting is not
+yet supported - on a server basis. Configuration may also have multiple
+services .. That is repeating service elements inside a server. Each
+has an attribute 'id' which serves as service ID. This ID in turn may
+be used in a Pazpar2 session, by specifying parameter service=ID for
+command init. There can be at most one unnamed service inside a server
+which can be referred to by not specifying an service ID for command
+init (backwards compatible). In order to partition multiple servers and
+services a new include directive has been added. This takes an attribute
+'src' which specifies one or more sub-files. For example to include
+service files, one might use:
+ <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
+It is the intention that that completely makes the settings directive
+redundant.
+
+Fix problem where the record command would wait forever if there were
+no targets to wait for (activeclients == 0).
+
+--- 1.1.1 2009/08/28
+
+One result set is created per session (last search) rather than for
+each connection which happen to be shared (bug #3009).
+
+marc21 stylesheets changed for efficiency.
+
+--- 1.1.0 2009/08/19
+
+Session timeout may be specified on the command-line as option -T.
+
+Pazpar2 may now be operated in a no-merged mode for records.. All records
+will be considered unique. This mode is enabled if no mergekey is
+generated by the normalization stylesheet (pz:xslt).
+
+Pazpar2 caches original records from each target and the 'record' command
+with offset returns the original record if 'syntax' and 'esn' are NOT
+specified. This speeds up retrieval of original records but also means
+that Pazpar2 uses more memory. The cached records will be freed when the
+session terminates or a new search is executed.
+
+Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
+library part of YAZ is used.
+
+Added SRU client support.
+
+Automatically computes pz:nativesyntax if not provided. Works for XML and
+MARC.
+
+--- 1.0.13 2008/11/24
+
+Command bytarget returns name of target (if defined).
+
+--- 1.0.12 2008/11/04
+
+Fixed bug #2021.. location now holds all brief elements.
+
+--- 1.0.11 2008/10/15
+
+Fixed check for application/x-www-form-urlencoded parameters.
+
+--- 1.0.10 2008/10/14
+
+Fixes for IE in pz2.js.
+
+Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
+
+--- 1.0.9 2008/05/23
+
+Changed the JS library pz2.js to use POST for long URL (+ params).
+
+Added installation instructions for Windows. Note: NT services is
+NOT available until we make a new release of YAZ.
+
+Preserve order of repeated metadata fields (they were reversed before).
+
+More MARC21 information extracted for metadata.
+
+--- 1.0.8 2008/04/22
+
+Fixed bug #1162: HTML entities are not escaped properly.
+
+Native Windows port of Pazpar2. Makefile for Visual Studio provided.
+
+--- 1.0.7 2008/04/14
+
+Marc21 stylesheet updated to reflect multiple full text fields
+
+--- 1.0.6 2008/03/12
+
+Fixed bug in pz2.js WRT DOMElement attributes on IE.
+
+Fixed bug 2100: Database wildcards not working
+
+--- 1.0.5 2007/11/09
+
+Added support for retrieval of records in binary.
+
+Fixed bug 1794: Pazpar2 does not return valid XML.
+
+Deal with ICU not returning sortkey (resulted in SEGV before).
+
+--- 1.0.4 2007/09/28
+
+JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
+other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
+
+Improved diagnostics when Pazpar2 HTTP decoding fails.
+
+Pazpar2 requests may be POSTed as using Content-Type
+application/x-www-form-urlencoded.
+
+Pazpar2 honors LF in HTTP headers.
+
+Handle targets that handle negative hit counts (should not happen, but it
+does).
+
+--- 1.0.3 2007/09/19
+
+ICU is used for tokenization and normalization of the following: mergekey,
+sorting, relevance terms.
+
+Debian package now enables ICU tokenization and normalization by default.
+
+--- 1.0.2 2007/08/22
+
+Exposed user setting values (i.e. non-pz: names) to the record systems in two
+ways: Either as parameters to the normalization stylesheets (which would allow the
+programmer to postprocess or use the values in any way) or after the normalization
+step, in which case values are made part of the normalized record (and available for
+sorting, termlists, display, or other interface-related use.
+
+Implemented sorting by year.
+
+Option -d dumps records to the current log file instead of stderr.
+
+Fixes for compilation on cygwin.
+
+Z39.50 client code uses pz:elements. pz:elements was recognized in
+earlier Pazpar2 versions but it was not used for anything.
+
+icu_chain_test is using fgets instead of getline - fixes compilation
+on MacOSX .
+
+Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
+query conversions fail (rather than _any_). This means targets that do
+not support some fields are ignored in a search.
+
+--- 1.0.1 2007/07/03
+
+Improved handling of socket timeout for Z39.50 connections.
+
+Misc documentation updates and spell fixes.
+
+Debian package pazpar2 creates log rotate entry.
+
+Debian package pazpar2-apache2 reloads Apache2.
+
+jsdemo included in distribution. It illustrates the use of the js/pz2.js
+JavaScript library.
+
+--- 1.0.0 2007/06/20
