Name cache optimization
-----------------------
The name-cache would cache all files of the same name to the same bucket,
which would put for instance all ".." entries in the same bucket. We added
the parent directory version to frustrate the hash, and improved the
management of the cache in various other ways while we were at it.

Less restrictive swap-spaces
----------------------------
The need to compile the names of the swap devices into the kernel has been
removed. Now swapon will accept any block devices, up to the maximum
number of swap devices configured in the kernel.

-------------
FreeBSD now supports a "slice" abstraction which makes it more
completely interoperable with other operating system partitions. This
support will eventually allow FreeBSD to inhabit DOS extended
partitions.

Support for Ontrack Disk Manager Version 6.0
--------------------------------------------
Support has been added for disks which use Ontrack Disk Manager.
The fdisk program does NOT know about it however, so make all changes
using the install program on the boot.flp or using Disk Managers tool.

Bad144 is back and working
--------------------------
Bad144 works again, though the semantics are slightly different than
before in that the bad-spots are kept relative to the slice rather
than absolute on the disk.

ProAudioSpectrum SCSI driver
----------------------------
If you have a PAS board with a CD-ROM, and the MS-DOS driver is called
TSLCDR.SYS, then the "pas" driver should work on your card. You can
attach disks, cdroms and tapes, but due to the nature of the hardware
involved, the transfer rate is limited to < 690 kbyte/sec. For CD-ROM
use, this is generally more than enough.
