+
+Requires YAZ-4.2.40 to support native solr support.
+
+Fix and improve logic handling whether or not to re-do search on sort
+order changes. A sort order with change in ascending/descending only
+whould not trigger a new search, which is required for targets with
+native sorting capabilities. Each client is now checked if instructions
+(sortmap) exist for native sorting and only client that does requires
+it is researched. Other clients is just re-ingesting the records,
+they already have. The resultset is now cleared if any researching
+is done.
+
+Connection sharing between session has broken since version 1.6.8 with
+introduction of logic that would minimize searching if pazpar2 could
+detect this based on same query and limits and partly sort order.
+This could lead to segementations violations.
+
+Added a chapter in the manaul about relevance ranking.
