FreeBSD是類UNIX操作系統，它基于加州伯克利大學的“4.4BSD-Lite”發行并帶有一些“4.4BSD-Lite2”增強，面向i386、amd64、IA-64、arm、MIPS、powerpc、ppc64、PC-98、UltraSPARC等平臺。它還間接地基于“386BSD”，此乃William Jolitz對加州伯克利大學的“Net/2”往i386系統上的移植，盡管如今只有極少的代碼保留下來。FreeBSD被全世界的公司、因特網服務提供商、科研人員、計算機專家、學生、家庭用戶等用于他們的工作、教育、娛樂中。FreeBSD帶有20000多個軟件包，它們是預編譯和打包好了、便于安裝的軟件，并覆蓋了廣闊的應用領域：服務器軟件、數據庫和網頁服務器、桌面軟件、游戲、網絡瀏覽器和商務軟件，而這一切都是免費和易于安裝的。

Glen Barber has announced the availability of the first release candidate for FreeBSD 8.4, the upcoming new stable version of the project's legacy branch: " The first RC build of the 8.4-RELEASE release cycle is now available on the FTP servers for the amd64, i386, and pc98 architectures. If you would like to use SVN to do a source based update of an existing system use 'releng/8.4'. If you would like to use csup/cvsup mechanisms instead the branch tag to use is 'RELENG_8_4'. Important notice when upgrading from 8.4-BETA1 to 8.4-RC1: there was an accidental breakage in the OpenSSL ABI in the BETA1 build that was fixed before this RC build. Applications built against OpenSSL may need to be rebuilt after upgrading to 8.4-RC1 from 8.4-BETA1.</span>" Read the rest of the release announcement for upgrade instructions.
