Release of Suricata 3.1!

We are pleased to announce the release of Suricata 3.1. This newest release of Suricata brings significant performance improvements including Hyperscan integration for Multi-Pattern Matcher, NETMAP usability enhancements, and simplifying rule grouping. The team also documented important changes since 3.1RC1 including AF_PACKETv2 is the default as v3 is still experimental and NFQ run mode workers were fixed.

The very best. Fully open source. Actively maintained. Crazy fast capable and accurate. That’s new @Suricata_IDS 3.1,” Michal Purzynski, Mozilla Corporation.
