Suricata 7.0.0 beta1 Release Notes

We are pleased to announce our beta version of the Suricata 7.0 release! We want to share the main work we’ll be releasing soon, so you can check and test it out, offer feedback and hopefully share your thoughts with us during SuriCon2022.

A few more issues (and features) should be covered for the stable version, but here are the main ones.

We know this took a lot of joint effort from our community, over difficult times, and we appreciate all your work in keeping improving and making Suricata always better. :slight_smile:
