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.
