[Elecraft] IOC Firmware REV Question

[Rod N0RC]

Hello,

When is the 1.07 Rev of the IOC required?

The K2 Rev B upgrade instructions say the IOC upgrade "...may be
needed..." and "...will be explained later...." [Page 3 second
paragraph], but the explanation is not offered. After sifting through
the Elecraft web site, it seems the new IOC firmware adds (at least)
KPA100 support, and is only needed if the KPA100 is added. Correct?

My IOC F/W is 1.02, the rig is operating FB, or did I not notice
something?
