You don't get to complain about the v25 version until you see its NEWS
complete. We aren't there yet.
But yes, I did look at all the changes in that file since 24.3
release, and all I saw was the one mentioned, and a couple of
bugfixes. That is all.

NEWS is not a manual, it only gives summary of the changes. If you
think the 2 manuals don't describe enough of the current behavior,
feel free to submit bug reports about specific deficiencies.
> 2. d-s-mode now supports rectangular regions (?).
I don't know what you are talking about, please give an example that
didn't work earlier. (AFAIK, it always supported rectangles in
conjunction with CUA mode, but maybe I'm mistaken.)

Read the commentary to the changeset. It was a bugfix related to CUA
features that used to work previously.

We never documented any of this, and I see no reason to do so now.
