+
+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.
