        * ldattach( is used to attach a line discipline to a serial line to allow for in-kernel processing of the received and/or sent data.

    New functionality:

        * eeprom( is now able to display the OpenPROM device tree on systems that have it.
        * Support for X11 on sgi has been added.

        * audio(4) received several bug fixes and enhancements including but not limited to improved recording and full-duplex support.
        * make(1) was heavily modified, mostly to improve support for parallel build. Parallel builds now run commands in the same way the sequential builds do, and the output from commands is more readable. A large part of the source tree, xenocara, and quite a few ports now build correctly with make -j.
        * rcs tools improvements and bug fixes.
        * RTM_VERSION was increased so that all routing messages could be modified to include additional fields for upcoming networking features.
        * sendbug(1) has stricter comment parsing, to avoid mangling diffs.

        * USB st(4) devices can now successfully disconnect.
        * More deviant umass devices accommodated.
        * svnd(4) devices now work on block devices.

        * mt(1) no longer triggers panics when processing the 'rewoffl' command.
        * raid(4) devices no longer hang when searching for components during boot.
        * sd(4) devices no longer receive spurious SYNCHRONIZE CACHE commands that confuse some hardware.
        * sd(4) no longer claim that SYNCHRONIZE CACHE commands are 16 bytes long when they are actually 10 bytes. Some devices took this too literally.
        * dhcpd( now always issues packets equal or larger than the minimum IP MTU.
        * The disklabel( -E mode does not allow manual editing of the 'c' partition, which is always set to cover the entire disk.
        * The disklabel( -E mode does not allow changing the cpg value of a partition.
        * The disklabel( -E mode command 'r' now displays the list of free chunks on the disk.
        * The disklabel( -E mode no longer permits assigning arbitrary sizes to FS_BOOT and FS_UNUSED partitions.
        * The bge(4) driver problems receiving jumbo frames have been resolved.
        * Many dangerous unsigned comparisons with -1 when checking the results of read and write calls have been eliminated.
        * The new M_ZERO flag for malloc(9) replaces many malloc+bzero/memset combinations, fixing a number of bugs in memory initialization and shrinking the kernel.
        * dhcpd( now correctly constructs response packets that use the overflow buffers to store options.
        * SCSI drivers are more reliable in MP machines due to better locking around command completion.
        * TCP responses to highly fragmented packets are now constructed without risking corruption of kernel memory.
        * Sockets now allow 4095 multicast group memberships.

    Install/Upgrade process changes:

        * All platforms now have serial console support when installing.
        * Serial console speed is detected and appropriate /etc/ttys entries automatically created.
        * OpenBSD/vax now also has both kinds of install ISO CD images.
        * DNS server addresses are remembered if an install is restarted.
        * OpenBSD/sgi can now be installed using the glass console.
