+* Modifications to the RF24 library in this fork is backward compatible. A single
+  enhancement which may cause issue, is code which relies on the driver to power down the
+  radio, as a side effect. The radio is no longer powered down after each transmit. Rather,
+  the application must take responsibility for power management. Normally this is
+  achieved by use of powerDown and powerUp. If you wish to maximize power efficiency,
+  you must call powerDown after transmit (write, startWrite).
