major ports/packages or release engineering practices. Clearly
the release notes cannot list every single change made to FreeBSD
between releases; this document focuses primarily on security

improvements. </p></div><div class="sect1"><div xmlns="" class="titlepage"><div><div><h2 xmlns="http://www.w3.org/1999/xhtml" class="title" style="clear: both"><a id="upgrade"></a>2. Upgrading from Previous Releases of FreeBSD</h2></div></div></div><p xmlns="http://www.w3.org/TR/xhtml1/transitional">[amd64,i386] Binary upgrades between RELEASE versions
