New sections in NEWS, you mean? I see.

No, I can't support that assumption. New tools, written today, are
probably written against a fairly current manual. Then someone
approaches you and says "I'd like to use your nice IDE on our stable
enterprise platform from three years ago which has an older GDB". The
range of supported GDBs does not only grow forwards.

I do think that such a section would be useful. I'm not entirely sure
about the distinction you are drawing, though. Is it a "what" versus
"why" difference?
