[Oisf-announce] Suricata 3.1RC1 is out

[Victor Julien]

We're happy to announce Suricata 3.1RC1. The plan is to release the
stable within a few weeks, so please help us test this release!

Lots of improvements on the performance side:

Hyperscan integration for MPM and SPM. If installed, Hyperscan is now
the default. See
https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Hyperscan

Rewrite of the detection engine, simplifying rule grouping. This reduces
memory usage and startup time in many scenarios.

Packet capture got a lot of love:
- AF_PACKET support for tpacketv3
- NETMAP usability improvements, especially on FreeBSD

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

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

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