This is the link for the new terms - they link on this page to the old version. You'd basically have to compare the two to check what's been updated. Significant changes would have to be announced properly, I'd think (this is usually a legal requirement, AFAIK), but if anyone wants to go through the two agreements to check, some internet points may be earned. 😅
