Wow great, but I wonder:

.... A new "hush" mode has been added which reduces the volume by a configurable
(from emplode) amount rather than muting it completely. This is achieved
by holding the pause button on the Rio remote (there is no Kenwood
equivalent). An 'H' appears in track details view if Hush is active....

Does this feature have a command for it on the serial port??

...A detailed info screen is now available for tracks. Press and hold the
"Info" button on the Rio remote to see this screen. Not available on the
Kenwood remote....

Does this mean that these features are not available when I only have the
Kenwood remote??

....Implemented visuals for Aux-In and Tuner....

Does this work for the MKI as well??
