+--- 1.6.20 2012/09/21
+
+Rank algorithm details may be printed as part of show reseponse in
+element <relevance_info>.. This is only printed if <rank debug="yes"/>
+is used in service.
+
+Record as returned by show/record command have a minimal indentation
+which makes things human-readable.
+
+--- 1.6.19 2012/09/18
+
+Rank algorithm skips strings that gets normalized to empty string.
+For example, & and ! could map to the empty string. The weight for
+those terms is now 0 (as if they were not part of the query).
+
+Rank algorithm does not use CCL from limitmap; only from the query
+parameter (user query).
+
+Obey -w dir.
+
+--- 1.6.18 2012/09/17
+
+Rank algorithm configurable by 'rank' element inside service. So far
+only, attribute 'cluster' is recognized. If cluster="yes", multiple
+records inside a cluster boosts higher than single records. This
+is default behavior and existing behavior. cluster="no" takes the
+average score of each record in a cluster.
+
+--- 1.6.17 2012/09/05
+
+Fix bad re-use of connections (connections with changing proxy should not
+be reused).
+
+--- 1.6.16 2012/08/22
+
+Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
+resultset and sorting when the sort order is position. However this will be done on
+every client poll, which will make pazpar2 continuing reset and fetching.
+It should only be done on FIRST request where the sort order change.
+
+Fix an issue on suggestion option: Also disable suggestions on empty string.
+
+Clean up in turbo marc stylesheet.
+
+Remove the hardcoded size of termlists.
+
+--- 1.6.15 2012/06/27
+
+New facility: ccldirective may be given in service definition. Allows
+CCL parsing to be customized a bit, such as defining names of operators
+and, or, not.
+
+New facility: raw record by checksum, rather than offset. The record
+command optionally takes checksum which identifies certain record from
+a database.
+
+New facility: per field ranking. Rank may be given as M [F N] where
+M is default rank and N is rank for CCL terms from field F.
+
+--- 1.6.14 2012/06/04
+
+Fix for IE7/8 in pz.js
+
+Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
+
+Lower log level some places.
+
+Remove some invalid test results.
+
+--- 1.6.13 2012/05/23
+
+Introducing a version=2 parameter for show, termlist and bytarget commands.
+This enables pazpar2 to return approximation on hit and count count when
+doing record filtering using the limit parameter on search and a
+limitmap with a value of "local:"
+
+Setting pz:xslt may embed local XSLT as an alternative to referring
+to filenames.
+Value is not CDATA but XML nodes embedded, so escaping is not necessary
+but a root element *must* be present. For example:
+<settings target="target="z3950.indexdata.com/marc">
+ <set name="pz:xslt">
+ <xsl:stylesheet
+ version="1.0"
+ ..
+ </xsl:stylesheet>
+ </set>
+ </settings>
+
+Metadata field rank may given by XML internal document (pz:xslt
+result). If rank is not given, the rank from service description is
+used - as before.
+
+Metadata field can now configured a default limitmap and facetmap.
+Setting limitmap to "local:" would work for all kind of targets, but would
+prob. not be the optimal solution. But at least better than the default behavior
+of pazpar2 where no filtering is done.
+
+A service definition can now also contains <set/> that defines service-wide
+settings. These will override server-wide sets and will be overridded by
+settings.
+
+New setting, pz:present_chunk, that specifies number of records to fetch
+at a time. Zero will disable chunkation; will fetch max_records at once.
+
+--- 1.6.12 2012/03/14
+
+Revert the format change in termlist response, that could break
+some clients / UIs since they were expecting an (empty) element
+if no facet values was found.
+
+--- 1.6.11 2012/03/07
+
+Revert the behavior of returning errors when unable to block
+on termlist, bytarget and search, when unable to block due to
+other block. The client will now receive a regular response,
+but it will be logged in the server. A parameter (report) is
+added to change behavior to return error response or WARNING
+status message. Consider this "API" as private, as it is mostly
+untested and could be changed in future releases.
+
+Fix spell error in pz2.js fix in 1.6.10.
+
+New Marc2TurboMarc.xsl (contribution from Sven Porst).
+Can solve the missing marc21.xsl updates in some cases.
+
+tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
+substring (contribtion from Sven Porst)
+
+marc21.xsl: fix 1-based substring call
+
+tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
+
+Add test_termlist_block to test suite
+
+--- 1.6.10 2012/02/23
+
+Fix SEGV for invalid PQFs and SRU/SOLR targets
+Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
+
+Fix pz2.js: "null object" due to change in in bytarget result XML.
+
+Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
+Added this normalization to the other subject-long fields (d6xx),
+where it was missing.
+
+Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
+Still differences around medium and holdings. marc21.xsl is not
+longer active used by Index Data, and should be considered unsupported.
+Use tmarc.xsl instead.
+
+--- 1.6.9 2012/01/19
+
+Fix SEGV that could occur for failed connections.
+
+--- 1.6.8 2012/01/17
+
+Fix bug for command sort that could return no results for active clients
+(from previous search). This bug was present in 1.6.6-1.6.7.
+
+Fix bug in results that could include results that should have been
+filtered out. This bug was present in 1.6.6-1.6.7.
+
+--- 1.6.7 2011/12/23
+
+Fix bug introduced in 1.6.6 where a connection re-use could stall
+incoming requests.
+
+Local filtering may now specify a local metadata field, eg.
+ pz:limitmap:somefield[t]=local:otherfield
+
+--- 1.6.6 2011/11/25
+
+For search, when limit and or filtering is in place and search
+is identical to previous search, the result set is re-used and the
+target is not searched.
+
+Limits may work perform local filtering as well, by using "local:"
+for a limitmap.
+
+--- 1.6.5 2011/11/01
+
+Updated bytarget command to contain a suggestions element with misspelled
+words and suggestions to these. pz2.js has been updated to deliver this
+onwards as well. Only target that currently delivers this is the solr
+client in YAZ 4.2.18.
+
+--- 1.6.4 2011/10/28
+
+New service definition element, xslt, that allows an embedded stylesheet
+to be defined. This can be referred to from pz:xslt as an alternative to
+external files.
+
+New pz:sortmap:field setting for specifying hints on how to make
+a target natively sort on a field. This is used for command=show in
+conjunction with sort.
+
+New pz:url setting for specifying the actual URL for a target. When
+this is used the target ID is not used as URL anymore and the target ID
+may be almost any string (not including []).
command=termlist without name parameter returns all termlists/facets.
Previously if name parameter was omitted, only "subject" was returned.
