-Blah blah blah
+This is a rather big release, we now [share plugins among zones in the same server
+block](https://github.com/coredns/coredns/pull/4593), which should save memory. Various bug fixes in
+a bunch of plugins and not one, but two new plugins. A *geoip* plugin that can report **where** the
+query came from and a *header* plugin that allows you to fiddle with (some of) the header bits in a
+DNS message.
