Do you mean like the 0810-Alpha and -Beta wiki pages? No, there is no such thing for 1004 (yet). The idea is that there are too many changes to list them all for the time being. Maybe when we enter beta, we will start making such a list again.
I do agree that a changelog would be useful, and perhaps we could list the main new stuff that has been worked on lately. Anyway, you can see what has been done in the trac timeline, although it might be a bit technical for some.
