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

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
