87  <para>This section describes the most user-visible new or changed
88    features in &os; since &release.prev;.  In general, changes
89    described here are unique to the &release.branch; branch unless

91
92  <para>Typical release note items document recent security advisories
93    issued after &release.prev;, new drivers or hardware support, new
94    commands or options, major bug fixes, or contributed software
95    upgrades.  They may also list changes to major ports/packages or
96    release engineering practices.  Clearly the release notes cannot
97    list every single change made to &os; between releases; this
98    document focuses primarily on security advisories, user-visible
99    changes, and major architectural improvements.</para>
