41 <title>Introduction</title>
43 <para>This document contains the release notes for &os;
44 &release.current;. It describes recently added, changed, or
45 deleted features of &os;. It also provides some notes on
46 upgrading from previous versions of &os;.</para>
48 <para releasetype="current">The &release.type; distribution to which
49 these release notes apply represents the latest point along the
50 &release.branch; development branch since &release.branch; was

71 <para>All users are encouraged to consult the release errata before
72 installing &os;. The errata document is updated with
73 <quote>late-breaking</quote> information discovered late in the
74 release cycle or after the release. Typically, it contains
75 information on known bugs, security advisories, and corrections to
76 documentation. An up-to-date copy of the errata for &os;
77 &release.current; can be found on the &os; Web site.</para>
81 <title>What's New</title>
83 <para>This section describes the most user-visible new or changed
84 features in &os; since &release.prev;. In general, changes
85 described here are unique to the &release.branch; branch unless
86 specifically marked as &merged; features.</para>
88 <para>Typical release note items document recent security advisories
89 issued after &release.prev;, new drivers or hardware support, new
90 commands or options, major bug fixes, or contributed software
91 upgrades. They may also list changes to major ports/packages or
92 release engineering practices. Clearly the release notes cannot
93 list every single change made to &os; between releases; this
94 document focuses primarily on security advisories, user-visible
95 changes, and major architectural improvements.</para>
