[Elecraft] Firmware Updates

[Bernie and Cheryl]

I got my K3s (#10323) back in October, 2015, and got my KPA 500 (#2664) 
a few months later (I have the full K line including the KAT 500).

When I built them, I promptly updated the firmware, and haven't done it 
since.  I checked and my K3s has Firmware Version 5.35 and the KPA 500 
has Version 1.38.

Am I missing anything by not having updated?  I haven't done it because 
I am maddened by the constant crazy updates forced on us by Microsoft, 
Firefox, etc. (when I turn on my computer, I want to USE it - when I 
turn it off, I want it to shut off, rather than update for another 10-15 
minutes), and just hate updates in principal.  However, I noticed that 
the interface between the K3s and my Ham Radio Deluxe software is 
getting a little glitchy (sometimes, the software insists the radio 
isn't there, even though I've checked the cable), and I wonder if that 
is a function of needing to update things (and yes, I should probably 
update the Ham Radio Deluxe software).  This glitchyness is the only 
problem I experience, and otherwise, my setup works great.

Thoughts?  What am I missing?
