K3 upgrade


My Old K3 is in for repair and upgrade.  I'm replacing the K3io board
with the new "B" model.  Apparently from what i read i will no longer
need the line in and line out cables.  Am i reading that correctly?  It
will then use a regular USB cable from the radio as a replacement as i
understand it.  Is there a new firmware release that will address this
or is the latest that has been published going to work?  I'm wondering
what different settings will have to be changed.  I use it mainly on CW
& FT8 modes.
