The highlights in the 6.4-RELEASE are the following:
* New and much-improved NFS Lock Manager (NLM) client
* Support for the Camellia cipher
* Boot loader changes allow, among other things, booting from USB devices and booting from GPT-labeled devices with GPT-enabled BIOSes
* DVD install ISO images for amd64/i386
* KDE updated to 3.5.10, GNOME updated to 2.22.3
* Updates for BIND, sendmail, OpenPAM, and others
FreeBSD 6.4-RELEASE is now available for the amd64, i386, pc98, and sparc64 architectures. The builds for the alpha architecture have not completed yet and will be announced later. FreeBSD 6.4-RELEASE 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", "docs", and "dvd1". 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 CDROM-sized (700MB media) and 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. In addition, "disc1" supports booting into a "live CD-based filesystem" and system rescue mode. The "docs" image has all of the documentation for all supported languages. The "dvd1" image is DVD-sized and includes everything that is on the CDROM discs. So "dvd1" can be used to do a full installation that includes a basic set of packages, it has all of the documentation for all supported languages, and it can be used for booting into a "live CD-based filesystem" and system rescue mode. Most people will find that "disc1", "disc2" and "disc3" are all that are needed if their machine does not have a DVD-capable drive. For people with machines that do have a DVD-capable drive "dvd1" should be all that is required. If you intend to install ports from source instead of using the pre-built packages included with the release only "disc1" is needed.
