My KN7000 has version 1.3 and when the later updates came out, I was also advised not to bother as it could cause unnecessary problems. As Bill says "if it ain't broke, don't fix it"

Just as a matter of interest - my Technics PR900 Piano was purchased in November 1996 and
the KN7000 was purchased in November 2002. Both have given me (and others) hours of pleasure with no problems at all and both are still in 'pristine' condition.

I hope Im not speaking too soon, but I do wonder whether today's instruments will last that long? Personally, I very much doubt it.
