FreeBSD 5.5-RELEASE Announcement

From: Ken Smith <>
Subject: [FreeBSD-Announce] FreeBSD 5.5 Released

It is my great pleasure and privilege to announce the availability of FreeBSD 5.5-RELEASE. Work done between the 5.4-RELEASE and this release has mostly been bugfixes. Some ``vendor supplied'' software has also been updated, mostly due to security concerns (specifically BIND and sendmail).

This is the last planned release on the 5-STABLE branch. The FreeBSD development community is currently focusing its efforts on the 6-STABLE and CURRENT codelines. No new major features are planned for the 5-STABLE branch, although minor updates and bugfixes may be merged at the discretion of individual developers. The FreeBSD security team will support the FreeBSD 5.5-RELEASE-based security branch with advisories and security patches until the end-of-life date documented at (as of this writing, May 31, 2008).

For a complete list of new features and known problems, please see the online release notes and errata list, available at:

FreeBSD 5.5-RELEASE supports the amd64, i386, pc98, alpha, and sparc64 architectures and can be installed directly over the net using bootable media or copied to a local NFS/FTP server. Distributions for all architectures are available now.

Please continue to support the FreeBSD Project by purchasing media from one of our supporting vendors. The following companies will be offering FreeBSD 5.5 based products:

If you can't afford FreeBSD on media, are impatient, or just want to use it for evangelism purposes, then by all means download the ISO images.

MD5 and SHA256 checksums for the release images are included at the bottom of this message.


5.5-RELEASE ISOs are not available via BitTorrent at this time. They may be made available in the future on an on-demand basis.
