Call for testing: Suricata 4.1rc2 released

Suricata 4.1rc2 is ready for testing. We’re hoping that this will be the final release candidate so that 4.1 can be released just before Suricon next month.

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 growth of Rust usage inside Suricata continues as most of the new protocols have been implemented in Rust.

Most important change for going from RC1 to RC2 is that we have enabled Rust support by default. If Rust is installed, it will be used.

  • TLS 1.3 parsing and logging (Mats Klepsland)
