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

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