35 <para>The release notes for &os; &release.current; contain
36 a summary of the changes made to the &os; base system on the
37 &release.branch; development line. This document lists
38 applicable security advisories that were issued since the last
39 release, as well as significant changes to the &os; kernel and

46 <title>Introduction</title>
48 <para>This document contains the release notes for &os;
49 &release.current;. It describes recently added, changed, or
50 deleted features of &os;. It also provides some notes on
51 upgrading from previous versions of &os;.</para>
53 <para>This distribution of &os; &release.current; is
54 a &release.type; distribution. It can be found at <uri
55 xlink:href="&release.url;">&release.url;</uri> or any of its
56 mirrors. More information on obtaining this (or other)
57 &release.type; distributions of &os; can be found in the <link

63 <para>All users are encouraged to consult the release errata
64 before installing &os;. The errata document is updated with
65 <quote>late-breaking</quote> information discovered late in the
66 release cycle or after the release. Typically, it contains
67 information on known bugs, security advisories, and corrections
68 to documentation. An up-to-date copy of the errata for &os;
69 &release.current; can be found on the &os; Web site.</para>
73 <title>What's New</title>
75 <para>This section describes the most user-visible new or changed
76 features in &os; since &release.prev;.</para>
78 <para>Typical release note items document recent security
79 advisories issued after &release.prev;, new drivers or hardware
80 support, new commands or options, major bug fixes, or
81 contributed software upgrades. They may also list changes to
82 major ports/packages or release engineering practices. Clearly
83 the release notes cannot list every single change made to &os;
84 between releases; this document focuses primarily on security
85 advisories, user-visible changes, and major architectural
