25 <title>Upgrading to 2.1 from 2.0</title>
28 <p>In order to assist folks upgrading, we maintain a document
29 describing information critical to existing Apache users. These
30 are intended to be brief notes, and you should be able to find
31 more information in either the <a
32 href="new_features_2_2.html">New Features</a> document, or in
33 the <code>src/CHANGES</code> file.</p>
35 <p>This document describes only the changes from 2.0 to 2.2. If you
36 are upgrading from version 1.3, you should also consult the <a
37 href="http://httpd.apache.org/docs-2.0/upgrading.html">1.3 to 2.0
38 upgrading document.</a></p>

53 <li>The config file <code>httpd.conf</code> distributed with the
54 Apache HTTP Server has been greatly simplified by removing all
55 but the most essential configuration settings. A set of example
56 configuration settings for more advanced features is present in
57 the <code>conf/extra/</code> directive of the installed
60 <li>The default setting of <directive
61 module="core">UseCanonicalName</directive> is now
62 <code>Off</code>. If you did not have this directive in your
63 config file, you can add <code>UseCanonicalName On</code> to
64 retain the old behavior.</li>
66 <li>The module <module>mod_userdir</module> will no longer act
67 on requests unless a <directive
68 module="mod_userdir">UserDir</directive> directive specifying a
69 directory name is present in the config file. To restore the
70 old default behavior, place the directive <code>UserDir
71 public_html</code> in your config file.</li>
