+    Release 2.9.0
+
+    This release brings a new message suppression option and a way to control
+    how many queries are sent over a connection.
+
+    You can now suppress the message about receiving unexpected DNS message
+    IDs by using `-O suppress=unexpected`.
+
+    With `-O num-queries-per-conn=<num>` you can now limit the number of
+    queries sent over a connection before triggering a re-connection, see
+    the `dnsperf(3)` man-page for more information how this works.

+This will limit the number of queries sent over a connection before
+triggering a re-connection. Once re-connected it will reset the counter and
+continue sending queries until the limit is reached again, triggering
+another re-connection and so on.
+Using this option will also enable counting number of responses received
+for each connection and once the limit is reached for sending queries it
+will wait until the same amount of responses has been received before
+re-connecting.
+Waiting for responses may timeout and the timeout used for this is the
