 v2.7.0 (XXXX-XX-XX)
 -------------------
 
+* AQL functon call arguments optimization
+
+  This will lead to arguments in function calls inside AQL queries will not be copied but passed
+  by reference. This may speed up calls to functions with bigger argument values or queries that
+  calls functions a lot of times.
+
 * upgraded V8 version to 4.3.61
 
 * removed deprecated AQL `SKIPLIST` function.
