Call for testing: Suricata 4.1rc1 released

It’s summer, so an excellent time for some testing! Suricata 4.1 release candidate 1 is here to be tried out. The release brings a lot of new features.

Get the release here: https://www.openinfosecfoundation.org/download/suricata-4.1.0-rc1.tar.gz

Main new features are inclusion of the protocols SMBv1/2/3, NFSv4, Kerberos, FTP, DHCP, IKEv2, as well as improvements on Linux capture side via AF_PACKET XDP support and on Windows IPS side via WinDivert. The progress in Rust usage inside Suricata continues as most of the new protocols have been implemented in Rust.

We invite everyone to test this release and report your experiences to us.
