If you’ve seen the `entropy` rule keyword in Suricata’s pre-8.0.0 code, there’s a [new blog post](https://suricata.io/2025/05/28/suricata-keyword-highlight-entropy/) that gives the background and how it can be used—special thanks to Chris Wakelin for the inspiration.

Well done, Jeff!  
I’ve spoken to others and they consider it a very useful addition to Suricata 8!
