The NEWS file may not be designed for that, but IMO, it still is way better than this text, which, for casual followers, doesn’t say much more than “1.4 replaces 1.3, no breaking changes, a few new features”, without even mentioning those features, or why they were added.
Maybe, combining the two in a single document, and copy-pasting NEWS.md in the announcement, would decrease the amount of work and improve things?
