Indeed, please be sure to mention such changes in NEWS.  Bonus points
for updating the relevant manual(s) as well.

We had in the past important changes that were left undocumented
because we forgot to update NEWS and the manuals when the code was
added.  So I'd like to urge everybody to please go extra mile and push
documentation changes together with code changes.

TIA
