+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.
+
+New configuration of default sorting criteria (sort-default) in 
+service definition. If no criteria is defined it will be as before
+'relevance'. 
+
+Search command now supports sort parameter just as the show command. 
+If no parameter is give, it will use the service sort-default value.

+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.

+
+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.

+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.
