56 <para>This document contains the release notes for &os;

58 deleted features of &os;. It also provides some notes on
59 upgrading from previous versions of &os;.</para>
61 <para releasetype="current">The &release.type; distribution to
62 which these release notes apply represents the latest point

88 <para>All users are encouraged to consult the release errata
89 before installing &os;. The errata document is updated with
90 <quote>late-breaking</quote> information discovered late in the
91 release cycle or after the release. Typically, it contains
92 information on known bugs, security advisories, and corrections
93 to documentation. An up-to-date copy of the errata for &os;
94 &release.current; can be found on the &os; Web site.</para>
96 <para>This document describes the most user-visible new or changed
97 features in &os; since &release.prev;. In general, changes
98 described here are unique to the &release.branch; branch unless
99 specifically marked as &merged; features.</para>
101 <para>Typical release note items document recent security
102 advisories issued after &release.prev;, new drivers or hardware
103 support, new commands or options, major bug fixes, or
104 contributed software upgrades. They may also list changes to
105 major ports/packages or release engineering practices. Clearly
106 the release notes cannot list every single change made to &os;
107 between releases; this document focuses primarily on security
108 advisories, user-visible changes, and major architectural
