First year books generally don't change much between editions. The professor may even provide the pages for previous versions. If they don't, then you'll have to figure out what sections you should be reading using the index. In the 4 years I've been at McMaster I've only heard of two instances where they changed actual books (not just the edition). Most of the time it doesn't even matter since a lot of first year students don't rely on the textbook at all. I know very few people who did learn directly from the textbook in first year.
The only thing is if editions change, the previous edition will be a lot cheaper. So if you bought a book now and it turns out to be a previous edition, you just lost quite a bit of money. Unless you can ONLY learn from a book and not from lecture, I would highly advise to buy previous editions because you would only be using the book as a reference and to solidify your understanding (Although you could also use the internet).
