<para>The release notes for &os; &release.current; contain
a summary of the changes made to the &os; base system on the

applicable security advisories that were issued since the last

<title>Introduction</title>
<para>This document contains the release notes for &os;
&release.current;. It describes recently added, changed, or
deleted features of &os;. It also provides some notes on
upgrading from previous versions of &os;.</para>
<para releasetype="current">The &release.type; distribution to
which these release notes apply represents the latest point
along the &release.branch; development branch since
&release.branch; was created. Information regarding pre-built,
binary &release.type; distributions along this branch can be
found at <uri
xlink:href="&release.url;">&release.url;</uri>.</para>
<para releasetype="snapshot">The &release.type; distribution to
which these release notes apply represents a point along the
&release.branch; development branch between &release.prev; and
the future &release.next;. Information regarding pre-built,
binary &release.type; distributions along this branch can be
found at <uri
xlink:href="&release.url;">&release.url;</uri>.</para>
<para releasetype="release">This distribution of &os;
&release.current; is a &release.type; distribution. It can be
found at <uri xlink:href="&release.url;">&release.url;</uri> or
any of its mirrors. More information on obtaining this (or
other) &release.type; distributions of &os; can be found in the

&os;</quote> appendix</link> to the <link
xlink:href="&url.books.handbook;/">&os;
Handbook</link>.</para>
<para>All users are encouraged to consult the release errata
before installing &os;. The errata document is updated with
<quote>late-breaking</quote> 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 &os;
&release.current; can be found on the &os; Web site.</para>
<para>This document describes the most user-visible new or changed
features in &os; since &release.prev;.</para>
<para>Typical release note items document recent security
advisories issued after &release.prev;, 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 &os;
between releases; this document focuses primarily on security
advisories, user-visible changes, and major architectural
improvements.</para>

<title>Upgrading from Previous Releases of &os;</title>
<para arch="amd64,i386">Binary upgrades between RELEASE versions
(and snapshots of the various security branches) are supported

procedure will update unmodified userland utilities, as well as
unmodified <filename>GENERIC</filename> kernel distributed as
a part of an official &os; release. The &man.freebsd-update.8;
utility requires that the host being upgraded have Internet
connectivity.</para>
<para>Source-based upgrades (those based on recompiling the &os;
base system from source code) from previous versions are
supported, according to the instructions in
