[Oisf-users] Suricata 4.0 rule fork

Wed Nov 29 23:21:28 UTC 2017

No more 1.x.  It will throw errors if you try to use the 2.x set.

Each set covers versions above it.  2.x set will run in anything above
2.0.  If running 4.0, that set will work, but you'll be missing out on the
new features we're targeting.
