* - Added new DATAFLASH_CHIP_MASK() macro to the Dataflash driver, which returns the Dataflash select mask for the given chip index
* - Updated MassStorage device block write routines to use ping-pong Dataflash buffering to increase throughput by around 30%
+ * - Added new HOST_STATE_WaitForDeviceRemoval host state machine state for non-blocking disabling of device communications until the
+ * device has been removed (for use when an error occurs or communications with the device have completed)
*
* <b>Changed:</b>
* - Deprecated psuedo-scheduler and removed dynamic memory allocator from the library (first no longer needed and second unused)
