Code:
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
      architecture.
    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
      hppa.
    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
      improvements.
    o i386 and amd64 use the BIOS disk geometry when creating default
      disklabels.
    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.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there https://tinyurl.com/ycpxl
