 Changes from iperf 2.x
 ----------------------
 
+(Note that iperf2 is no longer being developed by its original
+maintainers.  However, beginning in 2014, another developer began
+fixing bugs and enhancing functionality, and generating releases of
+iperf2.  Both projects (as of late 2017) are currently being developed
+actively, but independently.  The continuing iperf2 development
+project can be found at https://sourceforge.net/projects/iperf2/.)

 New options:
 
     -V, --verbose             more detailed output than before
