I agree with you generally, but I don't think that those other details
are needed in the NEWS item?  Your reasoning here was similar to my own
reasoning for suggesting that additions be made to the various relevant
nodes in the ert and elisp manuals:

We could add (elisp) Window Hooks to that list, in order to more
directly cover the window change functions.


My own feeling is still that the more general information belongs in
those manuals, and only the backwards-incompatibility notice is needed
in the NEWS.

I don't *object* to the other info being added to the NEWS, though --
this is a very minor point which doesn't warrant lots of discussion;
so if you feel it belongs in NEWS then let's do that.
