Release Engineering</a><br>
<small>Describes the approach used by the FreeBSD release
engineering team to make production quality releases of the
FreeBSD Operating System. It describes the tools available
for those interested in producing customized FreeBSD releases
for corporate rollouts or commercial
productization.</small></p></li>
<li><p><a href="&base;/doc/en_US.ISO8859-1/articles/releng-packages/index.html">FreeBSD
Release Engineering for Third Party Packages</a><br>
<small>Describes the approach used by the FreeBSD release
engineering team to produce a high quality package set
suitable for official FreeBSD release media. This document is
a work in progress, but eventually it will cover the process
used to build a clean package set on the FreeBSD.org "Ports
Cluster", how to configure any other set of machines as a
ports cluster, how to split up the packages for the release
media, and how to verify that a package set is
consistent.</small></p></li>
<li><p><a href="&base;/doc/en_US.ISO8859-1/articles/5-roadmap/index.html">FreeBSD
5-STABLE Roadmap</a><br>
<small>Described the roadmap for the project for reaching the RELENG_5
branch. Included overall status of 5.x, what was left to be done, and
tentative schedules. Note that this document is now mainly of
historical interest.</small></p></li>

<h2><a name="faq" id="faq">Frequently Asked Questions</a></h2>
<p>Where can I find the release directory or ISO images for older
FreeBSD releases?</p>
<p>The FreeBSD Project does not maintain a centralized historical
archive of old release ISO images, but there are still many
options. First, a large collection of the old releases (many
complete with the package sets) is at <a
href="ftp://ftp-archive.FreeBSD.org/pub/FreeBSD-Archive/old-releases/">
ftp://ftp-archive.FreeBSD.org/pub/FreeBSD-Archive/old-releases/</a>.
Second, try looking on <a
href="http://mirrorlist.FreeBSD.org">http://mirrorlist.FreeBSD.org</a>.
If you are unable to find an FTP mirror that still contains the
release you are looking for, then you can email CD-ROM vendors to
see if they have any old releases available. In September 2003,
we know of a case where FreeBSD 1.1 was used in a court of law to
invalidate a bogus software patent. Clearly, older releases can
be very important in some situations.</p>
