 * Added protocol specific metrics: histogram about request body size, total
   number of HTTP/2 connections and total number of VST connections.
 
+* Change the default value for the `--threads` startup parameter of the
+  following client tools from previously 2 to the maximum of 2 and the
+  number of available CPU cores:
+  - arangodump
+  - arangoimport
+  - arangorestore
+
+* Preselect "create index in background" option when creating indexes in
+  the web UI. The "create index in background" option can be less intrusive
+  because it allows other write operations on the collection to proceed.
+
+* Do not block a scheduler thread on the coordinator while an index is being 
+  created. Instead, start a background thread for the actual index 
+  fill-up work. The original thread can then be relinquished until the index
+  is completely filled or index creation has failed. This also allows
+  obsoleting the startup option `--cluster.index-create-timeout`, which from
+  now on is ignored when set.
+
 * Fix wrong assertion in fuerte and move it to where the TLA+ model says
   it should be. This fixes a unit test failure occurring on newer Macs
   with a certain clang version.
