40 <title>Introduction</title>
42 <para>This document contains the release notes for &os;
43 &release.current;. It describes recently added, changed, or
44 deleted features of &os;. It also provides some notes on
45 upgrading from previous versions of &os;.</para>
47 <para>This distribution of &os; &release.current; is a
48 &release.type; distribution. It can be found at <uri xlink:href="&release.url;">&release.url;</uri> or any of its mirrors. More
49 information on obtaining this (or other) &release.type;
50 distributions of &os; can be found in the <link xlink:href="&url.books.handbook;/mirrors.html"><quote>Obtaining

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