updated keywords list

 v2.8.0 (XXXX-XX-XX)
 -------------------
 
+* added AQL keywords `GRAPH`, `OUTBOUND`, `INBOUND` and `ANY` for use in graph 
+  traversals
+
+  Usage of these keywords as collection names, variable names or attribute names
+  in AQL queries will not be possible without quoting. For example, the following
+  AQL query will still work as it uses a quoted collection name and a quoted
+  attribute name:
+
+      FOR doc IN `OUTBOUND`
+        RETURN doc.`any`
+
 * issue #1593: added AQL `POW` function for exponentation
 
 * added cluster execution site info in explain output for AQL queries
