>   The FreeBSD Release Engineering Team is pleased to announce the availability
>   of FreeBSD 7.0-RELEASE.  This is the first release from the 7-STABLE branch
>   which introduces many new features along with many improvements to
>   functionality present in the earlier branches.  Some of the highlights:
>
>   - Dramatic improvements in performance and SMP scalability shown by various
>     database and other benchmarks, in some cases showing peak performance
>     improvements as high as 350% over FreeBSD 6.X under normal loads and
>     1500% at high loads.  When compared with the best performing Linux
>     kernel (2.6.22 or 2.6.24) performance is 15% better.  Results are from
>     benchmarks used to analyze and improve system performance, results with
>     your specific work load may vary.  Some of the changes that contribute
>     to this improvement are:
>
>         * The 1:1 libthr threading model is now the default.
>         * Finer-grained IPC, networking, and scheduler locking.
>         * A major focus on optimizing the SMP architecture that was
>           put in place during the 5.x and 6.x branches.
>
>     Some benchmarks show linear scaling up to 8 CPUs.  Many workloads see
>     a significant performance improvement with multicore systems.
>   - The ULE scheduler is vastly improved, providing improved performance
>     and interactive response (the 4BSD scheduler is still the default for
>     7.0 but ULE may become the default for 7.1).
>   - Experimental support for Sun's ZFS filesystem.
>   - gjournal can be used to set up journaled filesystems, gvirstor can
>     be used as a virtualized storage provider.
>   - Read-only support for the XFS filesystem.
>   - The unionfs filesystem has been fixed.
>   - iSCSI initiator.
>   - TSO and LRO support for some network drivers.
>   - Experimental SCTP (Stream Control Transmission Protocol) support
>     (FreeBSD's being the reference implementation).
>   - Much improved wireless (802.11) support.
>   - Network link aggregation/trunking (lagg(4)) imported from OpenBSD.
>   - JIT compilation to turn BPF into native code, improving packet capture
>     performance.
>   - Much improved support for embedded system development for boards
>     based on the ARM architecture.
>   - jemalloc, a new and highly scalable user-level memory allocator.
>   - freebsd-update(8) provides officially supported binary upgrades
>     to new releases in addition to security fixes and errata patches.
>   - X.Org 7.3, KDE 3.5.8, GNOME 2.20.2.
>   - GNU C compiler 4.2.1.
>   - BIND 9.4.2.

>   Availability
>   -------------
>
>   FreeBSD 7.0-RELEASE is now available for the amd64, i386, ia64, pc98,
>   and powerpc architectures.  The version for the sparc64 architecture will
>   become available in a few days.  Some of the package builds are still
>   in progress.
>
>   FreeBSD 7.0 can be installed from bootable ISO images or over the network;
>   the required files can be downloaded via FTP or BitTorrent as described in
>   the sections below.  While some of the smaller FTP mirrors may not carry all
>   architectures, they will all generally contain the more common ones, such as
>   i386 and amd64.
>
>   MD5 and SHA256 hashes for the release ISO images are included at the
>   bottom of this message.
>
>   The contents of the ISO images provided as part of the release has changed
>   for most of the architectures.  Using the i386 architecture as an example,
>   there are ISO images named "bootonly", "disc1", "disc2", "disc3", "livefs",
>   and "docs".  The "bootonly" image is suitable for booting a machine to do a
>   network based installation using FTP or NFS.  The "disc1", "disc2",  and
>   "disc3" images are used to do a full installation that includes a basic set
>   of packages and does not require network access to an FTP or NFS server
>   during the installation.  To boot into a "live CD-based filesystem" and
>   system rescue mode "disc1" and "livefs" are needed.  The "docs" image has
>   all of the documentation for all supported languages.  Most people will find
>   that "disc1", "disc2" and "disc3" are all that are needed if you want to
>   install some packages during the initial install, and just "disc1" if you
>   prefer to install packages after the initial install is completed.
>
>   FreeBSD 7.0-RELEASE can also be purchased on CD-ROM from several
>   vendors.  One of the vendors that will be offering FreeBSD 7.0-based
>   products is:
>
>   ~   FreeBSD Mall, Inc.        http://www.freebsdmall.com/
>
>
>   BitTorrent
>   ----------
>
>   7.0-RELEASE ISOs are available via BitTorrent.  A collection of torrent
>   files to download the images is available at:
>
>         http://torrents.freebsd.org:8080/
>
>
>   FTP
>   ---
>
>   The primary mirror site is:
>
>   ftp://ftp.freebsd.org/pub/FreeBSD/
>
>   However before trying the primary FTP site, please check your regional
>   mirror(s) first by going to:
>
>   ftp://ftp.<yourdomain>.FreeBSD.org/pub/FreeBSD
>
>   Any additional mirror sites will be labeled ftp2, ftp3 and so on.

>   Updating Existing Systems
>   -------------------------
>
>   An upgrade of any existing system to FreeBSD 7.0-RELEASE constitutes
>   a major version upgrade, so no matter which method you use to update an
>   older system you should reinstall any ports you have installed on the 
> machine.
>   This will avoid binaries becoming linked to inconsistent sets of libraries
>   when future port upgrades rebuild one port but not others that link to it.
>   This can be done with:
>
>         # portupgrade -faP
>
>   after updating your system.  Note some of the tools to help with this
>   or the instructions below for FreeBSD Update are not installed by default
>   (e.g. portupgrade, gpg, or similar tools like portmaster).
>
>
>   Updates from Source
>   -------------------
>
>   The procedure for doing a source code based update is described in the
>   FreeBSD Handbook:
>
>   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/synching.html
>   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
>
>   The branch tag to use for updating the source is RELENG_7_0.
>
>
>   FreeBSD Update
>   --------------
>
>   Starting with FreeBSD 6.3, the freebsd-update(8) utility supports binary
>   upgrades of i386 and amd64 systems systems running earlier FreeBSD releases,
>   release candidates, and betas.  Users upgrading to FreeBSD 7.0 from
>   older releases (in particular, older than 7.0-RC1) will need to
>   download an updated version of freebsd-update(8) that supports upgrading
>   to a new release.
>
>   # fetch http://people.freebsd.org/~cperciva/freebsd-update-upgrade.tgz
>
>   Downloading and verifying the digital signature for the tarball
>   (signed by the FreeBSD Security Officer's PGP key) is highly
>   recommended.
>
>   # fetch http://people.freebsd.org/~cperciva/freebsd-update-upgrade.tgz.asc
>   # gpg --verify freebsd-update-upgrade.tgz.asc freebsd-update-upgrade.tgz
>
>   The new freebsd-update(8) can then be extracted and run as follows:
>
>   # tar -xf freebsd-update-upgrade.tgz
>   # sh freebsd-update.sh -f freebsd-update.conf -r 7.0-RELEASE upgrade
>   # sh freebsd-update.sh -f freebsd-update.conf install
>
>   The system must be rebooted with the newly installed kernel before
>   continuing.
>
>   # shutdown -r now
>
>   Next, freebsd-update.sh needs to be run again to install the new userland
>   components, after which all ports should be recompiled to link to new
>   libraries:
>
>   # sh freebsd-update.sh -f freebsd-update.conf install
>   # portupgrade -faP
>
>   Finally, freebsd-update.sh needs to be run one last time to remove old
>   system libraries, after which the system should be rebooted in order
>   that the updated userland and ports will be running:
>
>   # sh freebsd-update.sh -f freebsd-update.conf install
>   # shutdown -r now
>
>   For more information, see:
