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. > > For a complete list of new features and known problems, please see the > online release notes and errata list, available at: > > http://www.FreeBSD.org/releases/7.0R/relnotes.html > http://www.FreeBSD.org/releases/7.0R/errata.html > > For more information about FreeBSD release engineering activities, > please see: > > http://www.FreeBSD.org/releng/ > > > 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. > > More information about FreeBSD mirror sites can be found at: > > http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/mirrors-ftp.html > > For instructions on installing FreeBSD, please see Chapter 2 of The > FreeBSD Handbook.

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: > > > http://www.daemonology.net/blog/2007-11-11-freebsd-major-version-upgrade.html > > > Support > ------- > > The FreeBSD Security Team currently plans to support FreeBSD 7.0 until > February 28th, 2009.
