Hey so... this is unofficial, but official. Back when we produced the Emerging Threats Suricata 7.0.3 rule fork, we said we would be stopping support for Suricata 4 effective immediately.Turns out that some customers were willing to pay for a stay of execution until the end of the year.The reaper is coming. If you're using the ET ruleset for Suricata 4 for any reason, and you still haven't made efforts to transition, the executioner is coming. very soon.
