<abstract>
<para>The release notes for &os; &release.current; contain a summary
of the changes made to the &os; base system on the
&release.branch; development line.
This document lists applicable security advisories that were issued since
the last release, as well as significant changes to the &os;
kernel and userland.
Some brief remarks on upgrading are also presented.</para>

<title>Introduction</title>
<para>This document contains the release notes for &os;
&release.current; on the &arch.print; hardware platform. It
describes recently added, changed, or deleted features of &os;.
It also provides some notes on upgrading
from previous versions of &os;.</para>
<![ %release.type.current [
<para>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 <ulink url="&release.url;"></ulink>.</para>
]]>
<![ %release.type.snapshot [
<para>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 <ulink url="&release.url;"></ulink>.</para>
]]>
<![ %release.type.release [
<para>This distribution of &os; &release.current; is a
&release.type; distribution. It can be found at <ulink
url="&release.url;"></ulink> or any of its mirrors. More
information on obtaining this (or other) &release.type;
distributions of &os; can be found in the <ulink
url="&url.books.handbook;/mirrors.html"><quote>Obtaining
&os;</quote> appendix</ulink> to the <ulink
url="&url.books.handbook;/">&os;
Handbook</ulink>.</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>

<sect1 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.historic;,
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>

and volume transaction queue depth.</para>
<para>A new GEOM-based disk encryption facility, GEOM_ELI, has been
added. It uses the &man.crypto.9; framework for hardware acceleration

<para>The &man.libmemstat.3; library has been added.
This is for use by debugging and monitoring applications
in tracking kernel memory statistics. It provides an

for the allocators. &merged;</para>
