[Elecraft] Firmware Upgrade

[Tom]

Hi gang,

  I'm installing the Automatic antenna unit to my K2 and will be adding the
PC interface (KIO2) unit in the near future.
As I understand it the interface unit comes with a firmware upgrade.  My K2,
s/n 1103 has firmware version 1.04d.

My question is whether or not a newer firmware version is on the way, or
should I just ahead and order the interface now?

Any thoughts or insights would be appreciated.

Thanks
Tom McCulloch, WB2QDG
