Since the release tour is a polished version of the merged tickets, I think the best source for that kind of information is trac. If you go here: http://trac.sagemath.org/sage_trac/roadmap?show=all you can see a description of each milestone (version number) and a link named "closed tickets" reveals what has happened. Of course, very technical, but at least the description of each milestone tells enough about it. In general, correct me if i'm wrong, major number changes happen if some underlying system is exchanged or a major part is rewritten; sub-minor number changes indicate bugfixes and fine grained improvements; the minor numbers are something in between. To answer the question, first point at 4.0 is "New symbolics based on pynac are the default." which changes the way symbolic expressions are handled. That's a major part, exposed everywhere in Sage and required a lot of work to accomplish.
