Suricata 3.1RC1 is out!
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 this guide.
- 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

Known issues & missing features
In a development release like this things may not be as polished yet. So please handle with care. That said, if you encounter issues, please let us know! As always, we are doing our best to make you aware of continuing development and items within the engine that are not yet complete or optimal. With this in mind, please notice the list we have included of known items we are working on. See issues for an up to date list and to report new issues. See Known_issues for a discussion and time line for the major issues.
