That's fine. I'm golden too - just updated to 1.02 myself, and have absolutely no AF problems (and I've been testing in low light on very low-contrast subjects). Can't say as I've noticed the AF assist light come on any more or less, incidentally.
Don't misunderstand me by the way, I don't think you're trying to convince or mislead anybody. I'm just speculating from the rather pessimistic tone of the post that perhaps you're seeing what your mind expects to. Frankly, I don't see a difference in noise before / after the 1.02 update - and had Pentax made any changes there I'd expect them to be touting it, and certainly wouldn't expect them to have made it worse even unintentionally.
The other changes don't touch any related image quality area, beyond that if you use the new higher-strength sharpening it's reasonable to expect that to possibly increase noise levels *when* it is applied, and not at any other time. On the contrary, if Pentax had done anything to work on noise, I'd expect them to be loudly advertising the fact. Fixing a little-noticed bug is something you do quietly so as not to call attention to your mistakes. Improving image quality in general, that's something you shout about to let everybody know you're the kind of company that hones and improves products.
