Suricata 3.2 available!
The OISF and Suricata development team is really proud to announce the availability of Suricata 3.2. This was a real community effort with 12 different contributors from 9 different countries that added to the work of Suricata core team. Thanks a lot for these contributions!
Suricata 3.2 comes with some new features that can help a Meerkat to stay awake when on a guard watch. The support of industrial networks has been greatly improved with the addition of two new protocols, DNP3 and CIP/ENIP. But we can’t forget the improvements on the TLS side with new fields available for matching and logging such as certificate validity dates. On file matching and logging, it is now possible to use SHA1/SHA256 in addition to the obsolete MD5.
On the performance side, Suricata 3.2 run as fast as a Cheetah with the addition of the bypass mechanism that can help to fix the challenging Elephant flows. Another big improvement comes from the pre-filter system that allows packet inspecting keywords to be much faster.
Documentation has received a huge overhaul, with PDF and other formats now available: http://suricata.readthedocs.io/en/suricata-3.2/
On usability side, one can note that incompatible NIC offloading is now switched off by default. Also, the unix command socket is now enabled by default.

- pre-filter — fast packet keywords
