[Elecraft] question about kat2 firmware

[Ted Roycraft]

I am trying to modernize a K2 I built four years ago
and haven't used in three years.  I've installed the
revision B upgrade but I have a question about the
KAT2 firmware.  My firmware for the KAT2 is version 1.03.
I notice that the current version is 1.07.  Can anyone
tell me what features were added or bugs were fixed
between 1.03 and 1.07?  I'd like to get my K2 up
to current version levels but I also can't help but
think "if it ain't broke, don't fix it".

Thanks.
