+This release makes the annotation `annotation-value-word-blocklist` backwards compatible by being an empty list instead of prescribed defaults.
+Effectively reverting [7874](https://github.com/kubernetes/ingress-nginx/pull/7874) but keeping the functionality of `annotation-value-word-blocklist`
+
+See Issue [7939](https://github.com/kubernetes/ingress-nginx/pull/7939) for more discussion
+
+Admins should still consider putting a reasonable block list in place, more information on why can be found [here](https://github.com/kubernetes/ingress-nginx/issues/7837) and how in our documentation [here](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#annotation-value-word-blocklist)
