upgrade process, to upgrade the system from sources via
buildworld to -CURRENT or 11.0-RELEASE, it is necessary to
upgrade machines running 9.x to at least revision r286035,
or machines running 10.x to revision r286033. Source-based
upgrades from 10.3-RELEASE are not affected. This differs
from the historical situation where one could generally
upgrade from anywhere on earlier stable branches, so caution
should be exercised. </p></li></ul></div></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="late-news"></a>5. Late-Breaking News</h2></div></div></div><p xmlns="http://www.w3.org/TR/xhtml1/transitional">No news. </p></div></div><p xmlns="http://www.w3.org/TR/xhtml1/transitional" align="center"><small>This file, and other release-related documents,
