The release notes for FreeBSD 8.0-RELEASE contain a summary of the changes made to the FreeBSD base system on the 8.0-STABLE development line. This document lists applicable security advisories that were issued since the last release, as well as significant changes to the FreeBSD kernel and userland. Some brief remarks on upgrading are also presented. NOTE: the full release notes were not available at the time the release builds were started. See the online version of the release notes for the most up to date information.

It describes recently added, changed, or deleted features of FreeBSD. It also provides some notes on upgrading from previous versions of FreeBSD. This distribution of FreeBSD 8.0-RELEASE is a release distribution. It can be found at [url]http://www.FreeBSD.org/[/url] or any of its mirrors. More information on obtaining this (or other) release distributions of FreeBSD can be found in the "Obtaining FreeBSD" appendix to the FreeBSD Handbook. All users are encouraged to consult the release errata before installing FreeBSD. The errata document is updated with "late-breaking" information discovered late in the release cycle or after the release. Typically, it contains information on known bugs, security advisories, and corrections to documentation. An up-to-date copy of the errata for FreeBSD 8.0-RELEASE can be found on the FreeBSD Web site. -------------------------------------------------------------- 2 What's New This section describes the most user-visible new or changed features in FreeBSD since 7.2-RELEASE. In general, changes described here are unique to the 8.0-STABLE branch unless specifically marked as MERGED features. Typical release note items document recent security advisories issued after 7.2-RELEASE, new drivers or hardware support, new commands or options, major bug fixes, or contributed software upgrades. They may also list changes to major ports/packages or release engineering practices. Clearly the release notes cannot list every single change made to FreeBSD between releases; this document focuses primarily on security advisories, user-visible changes, and major architectural improvements. -------------------------------------------------------------- 2.1 Security Advisories -------------------------------------------------------------- 2.2 Kernel Changes 2.2.1 Boot Loader Changes -------------------------------------------------------------- 2.2.2 Hardware Support 2.2.2.1 Multimedia Support -------------------------------------------------------------- 2.2.2.2 Network Interface Support -------------------------------------------------------------- 2.2.3 Network Protocols -------------------------------------------------------------- 2.2.4 Disks and Storage -------------------------------------------------------------- 2.2.5 File Systems -------------------------------------------------------------- 2.3 Userland Changes 2.3.1 /etc/rc.d Scripts -------------------------------------------------------------- 2.4 Contributed Software -------------------------------------------------------------- 2.5 Ports/Packages Collection Infrastructure -------------------------------------------------------------- 2.6 Release Engineering and Integration -------------------------------------------------------------- 2.7 Documentation -------------------------------------------------------------- 3 Upgrading from previous releases of FreeBSD [amd64, i386] Beginning with FreeBSD 6.2-RELEASE, binary upgrades between RELEASE versions (and snapshots of the various security branches) are supported using the freebsd-update(8) utility. The binary upgrade procedure will update unmodified userland utilities, as well as unmodified GENERIC or SMP kernels distributed as a part of an official FreeBSD release. The freebsd-update(8) utility requires that the host being upgraded have Internet connectivity. An older form of binary upgrade is supported through the Upgrade option from the main sysinstall(8) menu on CDROM distribution media. This type of binary upgrade may be useful on non-i386, non-amd64 machines or on systems with no Internet connectivity. Source-based upgrades (those based on recompiling the FreeBSD base system from source code) from previous versions are supported, according to the instructions in /usr/src/UPDATING. Important: Upgrading FreeBSD should, of course, only be attempted after backing up all data and configuration files. -------------------------------------------------------------- This file, and other release-related documents, can be downloaded from [url]http://www.FreeBSD.org/[/url].
