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

<title>Run-Time Configuration Changes</title>
<ul>
<li>The config file <code>httpd.conf</code> distributed with the
Apache HTTP Server has been greatly simplified by removing all
but the most essential configuration settings. A set of example
configuration settings for more advanced features is present in
the <code>conf/extra/</code> directory of the installed
server.</li>
<li>The <program>apachectl</program> option
<code>startssl</code> is no longer available. To enable ssl
support, you should edit <code>httpd.conf</code> to include the
relevant <module>mod_ssl</module> directives and then use
<code>apachectl start</code> to start the server. An example
configuration to activate <module>mod_ssl</module> has been included
in <code>conf/extra/httpd-ssl.conf</code>.</li>
<li>The default setting of <directive
module="core">UseCanonicalName</directive> is now
<code>Off</code>. If you did not have this directive in your
config file, you can add <code>UseCanonicalName On</code> to
retain the old behavior.</li>
<li>The module <module>mod_userdir</module> will no longer act
on requests unless a <directive
module="mod_userdir">UserDir</directive> directive specifying a
directory name is present in the config file. To restore the
old default behavior, place the directive <code>UserDir
public_html</code> in your config file.</li>
