newRPL - build 1255 released! [updated to 1299]

A side note:

On the models that support USB power, the battery indicator will turn gray when the USB cable is plugged, to indicate it's drawing power from the USB port.

USB comms require the CPU to run faster than the usual idle speed, so power consumption goes up when you are plugged in. This is not a problem on the newer models that support USB power, but might drain your batteries faster on the older models that don't take power from USB.
Also keep in mind while a USB connection is active the auto-off feature is disabled to preserve the connection and the ability to respond to remote commands. A non-issue when using USB power but keep it in mind for the older models.
