<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

<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>

<sect1 xml:id="new">
<title>What's New</title>
<para>This section describes the most user-visible new or changed
features in &os; since &release.prev;. In general, changes
described here are unique to the &release.branch; branch unless
specifically marked as &merged; features.</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>
