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

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