<p>This document contains the release notes for FreeBSD 6.4-RELEASE on the Alpha/AXP
hardware platform. It describes recently added, changed, or deleted features of FreeBSD.
It also provides some notes on upgrading from previous versions of FreeBSD.</p>
<p>This distribution of FreeBSD 6.4-RELEASE is a release distribution. It can be found at
<a href="ftp://ftp.FreeBSD.org/" target="_top">ftp://ftp.FreeBSD.org/</a> or any of its
mirrors. More information on obtaining this (or other) release distributions of FreeBSD
can be found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/mirrors.html"
target="_top">“Obtaining FreeBSD” appendix</a> to the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>.</p>
<p>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 6.4-RELEASE can be found on the FreeBSD Web site.</p>

<hr />
<h2 class="SECT1"><a id="NEW" name="NEW">2 What's New</a></h2>
<p>This section describes the most user-visible new or changed features in FreeBSD since
6.3-RELEASE.</p>
<p>Typical release note items document recent security advisories issued after
6.3-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.</p>

blocks are written to the server before obtaining locks (allowing multiple clients to use
file locking to safely share data). Also, a new kernel option <tt class="LITERAL">options
NFSLOCKD</tt> has been added and enabled by default. If the kernel support is enabled, <a
