[Oisf-announce] Suricata 4.1 released

[Victor Julien]

After a longer than intended release development cycle, the OISF
development team is proud to present Suricata 4.1.

Main new features are inclusion of the protocols SMBv1/2/3, NFSv4,
Kerberos, FTP, DHCP, IKEv2. All of them have been implemented in Rust to
ensure their introduction will not be compromising to the security and
the stability of the complete system.

Support for tracking and logging TLS 1.3 has been added, including JA3
support.

On performance side, one of the main improvements is the availability of
capture bypass for AF_PACKET implemented on top of the new eXpress Data
Path capability of Linux kernel. Windows users will benefit of the 4.1
release with a new IPS mode based on WinDivert.

All new protocols require Rust so Suricata 4.1 is not really 4.1 if you
don't have Rust. This is why the build system is now enabling Rust by
default if it is available on the build machine.

This is the first release where Suricata-Update 1.0, the new Suricata
rule updater, is bundled.
