We're proud to announce *Suricata 3.1*.

This release brings significant improvements on the performance side:
- Hyperscan integration for Multi Pattern Matcher and Single Pattern
  Matcher. If installed, Hyperscan is now the default.
- Rewrite of the detection engine, simplifying rule grouping. This
  improves performance, while reducing memory usage and startup time
  in many scenarios.

Packet capture got a lot of attention:
- AF_PACKET support for tpacket-v3 (experimental)
- NETMAP usability improvements, especially on FreeBSD

- Reorganised default configuration layout provides for intuitive
  and easy set up.

This release also comes with libhtp 0.5.20, in which we address a number
of issues Steffen Ullrich of HTTP Evader reported.

A new keyword ‘tls_sni’ was added, including MPM support. It allows
matching on the TLS SNI field.

Other than that, lots of cleanups and optimizations:
- locking has been much simplified
- TCP and IPv6 decoder optimizations
- unittest cleanups
- AFL fuzz testing options were added

Have a look at the full changelog:

*Changes since 3.1RC1*

- AF_PACKETv2 is the default as v3 is still experimental.
- NFQ runmode workers was fixed.
