<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
release, as well as significant changes to the &os; kernel and

<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

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>

<para revision="282065" contrib="sponsor" sponsor="&ff;">The
<literal>PAE_TABLES</literal> kernel configuration option has
been added for &os;/&arch.i386;, which instructs &man.pmap.9;
to use <acronym>PAE</acronym> format for page tables while
maintaining a 32-bit physical address size elsewhere in the
kernel. The use of this option can enhance application-level
security by enabling the creation of <quote>no execute</quote>
mappings on modern &arch.i386; processors. Unlike the
<literal>PAE</literal> option, <literal>PAE_TABLES</literal>
preserves kernel binary interface (<acronym>KBI</acronym>)
compatibility with non-<literal>PAE</literal> kernels,
allowing non-<literal>PAE</literal> kernel modules and drivers
to work with a <literal>PAE_TABLES</literal>-enabled kernel.
