-from the KAME project.
-This includes addition of kernel code for IPv6/IPsec,
-IPv4/v6 dual-stack user applications and supporting libraries.
-Due to this, the shlib major version for
-.Xr pcap 3
-is incremented and you may need to recompile userland tools.
-The KAME IPv6 part includes results from the unified-IPv6 effort.
+Hardware assisted IPv4 TCP and UDP checksumming and for caching of the
+IPv6 TCP pseudo header.

-.Sq NTFS
-file system (read-only at this stage).
+.Xr dump 8 ,
+.Xr dumpfs 8 ,
+.Xr fsck_ffs 8 ,
+.Xr fsirand 8 ,

-Support for revision 1 of the
-.Tn Linux
-.Sq ext2fs
-file system.
+Added
+.Xr makefs 8 ,
+which creates file system images from a directory tree.
+(Currently ffs only.)
 .It
-Enhanced stability and usability of LFS (the
-.Bx
-log-structured file system).
-.It
-Various RAIDframe enhancements including: auto-detection of RAID components
-and auto-configuration of RAID sets, and the ability to configure the root

-including the AES cipher Rijndael, the OpenSSL library, more
-complete Kerberos IV and Kerberos V support, and an SSH server
-and client.
-.It
-.Xr sysctl 3
-interfaces to various elements of process and system information,
-allowing programs such as
-.Xr ps 1 ,
-.Xr dmesg 1
-and the like to operate without recompilation after kernel upgrades,
-and remove the necessity to run setgid kmem (thus improving system
-security).

+.Xr passwd.conf 5 .
 .It
-Several code audits were performed.
-One audit replaced string routines that were used without bounds checking,
-and another one identified and disabled places where format strings were
-used in unsafe ways, allowing arbitrary data to be entered by (possibly)
-malicious users to overwrite application code, and leading from
-Denial of Service attacks to compromised systems.
-.It
-.Xr sshd 8
-and
-.Xr ssh 1
-now require
-.Xr rnd 4
-kernel random number devices.
+Several more code audits were performed.
