Difference between TI-92 ROM versions?

I purchased a very early TI-92 (ROM v1.2), and my math class is going to
be using them this coming year. What is the latest ROM version? I know
that my version has some problems with e, the natural logarithm. I
compared answers I got on the 92 to answers a friend of mine got doing the
problems by hand. His answers were nothing like the ones I got. (Yes, they
were right! :) Has this problem been fixed? Are there any other major
differences between ROM versions? I don't think one or two versions would
be that big of a deal, but if the difference is that big, is it worth
buying a new calc?
