    As in our previous releases, 4.2 provides significant improvements,
    including new features, in nearly all areas of the system:
    - New/extended platforms:
        o OpenBSD/sparc64.
          The PCIe UltraSPARC IIIi machines like the V215 and V245 are
          now supported.
        o OpenBSD/hppa.
          Four-digit B/C/J-class workstations like the B2000, C3750 or J6750
          are now supported (in 32-bit mode).
        o OpenBSD/alpha.
          Add support in the alpha platform for a couple of new Alpha models,
          AlphaServer 1200 and 4100.
    - Platforms skipped this release:
        o OpenBSD/sgi.
          This architecture will not be released this time. 
    - Install/Upgrade process changes:
        o New install method!!
          For the most popular architectures, the FTP sites have a ~200MB
          install ISO file, which contains the base set, permitting
          non-network installs.
        o Allow the specification of an NTP server during installation.
        o Allow no fsck'ing of clean non-root partitions during upgrade.
        o Check for INSTALL.<arch> to confirm sets are for the correct
        o Create and format the MSDOS partition for macppc installs
          in a more flexible and reliable way. 
    - Improved hardware support, including:
        o Native Serial-ATA support:
          o ahci(4) driver for SATA controllers conforming to the Advanced
            Host Controller Interface specification.
          o jmb(4) driver for the JMicron JMB36x SATA II and PATA Host Controller.
          o sili(4) driver for SATA controllers using the Silicon Image
            3124/3132/3531 SATALink chipsets. 
        o The pciide(4) driver has had support added for newer chipsets, including:
          o Intel ICH8M PATA
          o JMicron JMB36x PATA
          o VIA CX700/VX700 PATA 
        o The lm(4) driver now supports Winbond W83627DHG and W83627EHF-A 
          Super I/O Hardware Monitors.
        o The siop(4) driver now has support for NCR 53C720/770 controllers in
          big endian mode. In particular this means that the onboard Fast-Wide
          SCSI on many hppa machines is supported now.
        o New tht(4) driver for Tehuti Networks 10Gb Ethernet controllers.
        o The malo(4) driver now supports Marvell 88W8385 802.11g based
          Compact Flash devices.
        o New uts(4) driver for USB touch screens, supported by the xtsscale(1)
          calibration utility.
        o The i810(4) X.Org driver and the PCI AGP driver now support
          Intel i965GM chips.
        o New led(4) driver for the front panel LEDs on the V215/245.
        o New bbc(4) driver providing support for the BootBus Controllers in
          UltraSparc III systems.
        o New pmc(4) driver for the watchdog(4) timer on the National Semiconductor
          PC87317 SuperIO chip.
        o New pyro(4) driver for the SPARC64 Host/PCIe bridge.
        o New astro(4) driver for the Astro Memory and I/O controller on hppa.
        o New elroy(4) driver for the Elroy PCI hostbridge on hppa.
        o New lcd(4) driver for the front panel LCD display on hppa.
        o New ssio(4) driver for the National Semiconductor PC87560 Legacy IO on
        o New pxammc(4) driver for the MMC/SD/SDIO controller on zaurus.
        o New xlights(4) driver for the front panel lights on the Xserve G4.
        o New sysbutton(4) driver for the system identification button on
          the Xserve G4.
        o New piixpcib(4) driver for System Management Mode initiated speedstep
          frequency scaling on certain pairings of the Intel PIIX4 ISA bridges
          and Intel Pentium 3 processors.
        o CPU frequency and voltage can now be scaled on all CPUs when running
          GENERIC.MP on a multiprocessor i386 or AMD64 machine with enhanced
          speedstep or powernow.
        o Intel enhanced speedstep is now supported on OpenBSD/amd64.
        o New support for the on die CPU temperature sensor found on the
          Intel Core family of processors.
        o The nvram(4) driver is now available on OpenBSD/amd64. 
    - New tools:
        o cwm(1) has replaced wm2 as a simple-looking low-resource window manager.
        o zless(1), view compressed files with less(1).
        o mount_vnd(8), a utility to configure vnode disks from fstab(5).
    - New functionality:
        o FFS2, the updated version of the fast file system.
        o ftp(1) now can send cookies loaded from a netscape-like cookiejar,
          supports proxies requiring a password, and has a keep-alive option
          to avoid over-aggressive control connection dropping.
        o pkg_add(1) has been vastly improved. It is more robust, outputs more
          consistent error messages, and can deal with a lot more update
          scenarios gracefully. It also has much better look-up capabilities for
          multiple entries in PKG_PATH, stopping at the first directory with
          suitable candidates.
        o ftp-proxy(8) is now able to automatically tag packets passing through
          the pf(4) rule with a supplied name.
        o Kernel work queues, workq_add_task(9), workq_create(9),
          workq_destroy(9) provides a mechanism to defer tasks to a process
          context when it is impossible to run such a task in the current context.
        o ifconfig(8) now understands IP address/mask in CIDR notation.
        o Add IP (v4 and v6) load balancing to carp(4), similar to the
          ARP balancing.
        o sensorsd(8)  now supports a zero-configuration monitoring and has
          a more intuitive logging for all sensors that automatically provide
          sensor state.  It also features advancements in user-specified
          monitoring, including monitoring of sensors that are periodically
          flagged as invalid.
        o sensorsd.conf(5) now supports sensor matching by sensor type,
          allowing easier configuration.
        o The i386 bootloader can now load amd64 kernels.
        o The amd64 bootloader can now load i386 kernels.
    - Assorted improvements and code cleanup:
        o Large (>1TB) disk and partition support in the disklabel and buffer
          cache code and in the userland utilities that manipulate disk blocks.
          Note that some parts of the system are not 64-bit disk block clean
          yet, so partitions larger than 2TB cannot be used at the moment.
        o Large (>2^32-1 sectors) SCSI disk sizes now probed.
        o Thread support for the Objective-C library (libobjc).
        o carp route handling has been fixed, solving some problems the
          routing daemons were exhibiting.
        o Various improvements in pf increase performance drastically,
          stateful passing more than twice as fast than before.
        o A change in how the kernel random pool is stirred increases performance
          with network interface cards that support interrupt mitigation a lot.
        o i386 TLB handling improved to avoid possible corruption on
          Core2Duo processors.
        o Rework TLB shootdown code for i386 and amd64, gives fairly large speed
        o i386 and amd64 use the BIOS disk geometry when creating default
        o Default disk geometry changed from 64 heads/32 sectors to
          255 heads/63 sectors.
        o More USB devices with various quirks coerced to work.
        o Archive/Wangtek cartridge tape drives (wt*) no longer supported.
        o rcs has improved GNU compatibility.
        o make(1) has improved stability of -j option.
