<h1>Introduction</h1>

<p>This is a specific schedule for the release of FreeBSD 5.1.  For
  more general information about the release engineering process,
  please see the <a href="&base;/releng/index.html">Release
  Engineering</a> section of the web site.</p>

<p>General discussions about the release engineering process or
  quality assurance issues should be sent to the public <a
  href="mailto:FreeBSD-qa@FreeBSD.org">FreeBSD-qa</a> mailing list.
  <a
  href="&base;/doc/en_US.ISO8859-1/books/faq/misc.html#DEFINE-MFC">MFC</a>
  requests should be sent to <a
  href="mailto:re@FreeBSD.org">re@FreeBSD.org</a>.</p>

<p>One of the major features of FreeBSD 5.1 will be further refinement of
  the re-worked SMP support introduced in FreeBSD 5.0.  For specific
  information about the progress towards 5.1-RELEASE in this area, please
  see the <a href="&base;/smp/index.html">SMP Project</a> page.</p>

<p>FreeBSD 5.1 will continue to be released from the 5-CURRENT development
  stream.  For more details about the milestones for reaching
  5-STABLE, see the <a href="&base;/doc/en/articles/5-roadmap">5-STABLE
  Roadmap</a> page.</p>

<p>The current release engineering <a
  href="&base;/releases/5.1R/todo.html">TODO list</a> is also available.
  This list is updated periodically through the release cycle.</p>
