Hello, my name is Steve, and this is my first post after several months of "lurking". I've looked through the substitution sticky and I appreciate all the advice that everyone has posted.

I have a test coming up, and a few months ago I purchased some QuickFix 4.0. I've noticed that there is now a 4.2, and I have seen people recommend switching to 4.0 if they have 3.0, but not so much about the difference between 4.0 and 4.2. The only thing I could really find is that 4.2 is less proven than 4.0, obviously because is it newer. Just wondering if anyone knows specifically what the difference is between the two? I am also assuming the majority of people are still using 4.0 successfully?

My other question is about the temp. strip on the bottle. I've seen a few people post that the strip is off. Just wondering if anyone knows if it reads higher or lower than the actual temp, and by how much? Ya, I know, get a digital thermometer. I am really low on money and I have to take this mediocre job to pay back loans for the degree that I'm not even using, so the digi isn't really an option.

Any help that you guys can give me is appreciated. I'll try to make a post about my experience with QF as the date approaches. I'm practicing with bottle under my balls as we speak, enjoy that mental image.
