37      <para>The release notes for &os; &release.current; contain
38	a summary of the changes made to the &os; base system on the
39	&release.branch; development line.  This document lists
40	applicable security advisories that were issued since the last
41	release, as well as significant changes to the &os; kernel and
42	userland.  Some brief remarks on upgrading are also
43	presented.</para>

50    <para>This document contains the release notes for &os;
51      &release.current;.  It describes recently added, changed, or
52      deleted features of &os;.  It also provides some notes on
53      upgrading from previous versions of &os;.</para>

55    <para>This distribution of &os; &release.current; is
56      a &release.type; distribution.  It can be found at <uri

58      mirrors.  More information on obtaining this (or other)

65    <para>All users are encouraged to consult the release errata
66      before installing &os;.  The errata document is updated with
67      <quote>late-breaking</quote> information discovered late in the
68      release cycle or after the release.  Typically, it contains
69      information on known bugs, security advisories, and corrections
70      to documentation.  An up-to-date copy of the errata for &os;
71      &release.current; can be found on the &os; Web site.</para>

80    <para>Typical release note items document recent security

84      major ports/packages or release engineering practices.  Clearly
85      the release notes cannot list every single change made to &os;
86      between releases; this document focuses primarily on security
87      advisories, user-visible changes, and major architectural
