46    <para>The release notes for &os; &release.current; contain
47      a summary of the changes made to the &os; base system on the
48      &release.branch; development line.  This document lists
49      applicable security advisories that were issued since the last
50      release, as well as significant changes to the &os; kernel and
51      userland.  Some brief remarks on upgrading are also

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

90    release cycle or after the release.  Typically, it contains
91    information on known bugs, security advisories, and corrections to

93    &release.current; can be found on the &os; Web site.</para>

99  <para>This section describes the most user-visible new or changed
100    features in &os; since &release.prev;.</para>
101
102  <para>Typical release note items document recent security advisories
103    issued after &release.prev;, new drivers or hardware support, new
104    commands or options, major bug fixes, or contributed software
105    upgrades.  They may also list changes to major ports/packages or
106    release engineering practices.  Clearly the release notes cannot
107    list every single change made to &os; between releases; this
108    document focuses primarily on security advisories, user-visible
109    changes, and major architectural improvements.</para>
