+    <title>Core Enhancements</title>
+
+    <dl>
+      <dt><strong>Unix Threading</strong></dt>
+
+      <dd>On Unix systems with POSIX threads support, Apache can
+      now run in a hybrid multiprocess, multithreaded mode. This
+      improves scalability for many, but not all configurations.</dd>
+
+      <dt><strong>New Build System</strong></dt>
+
+      <dd>The build system has been rewritten from scratch to be
+      based on autoconf and libtool. This makes Apache's
+      configuration system more similar to that of other
+      packages.</dd>
+
+      <dt><strong>Multiprotocol Support</strong></dt>
+
+      <dd>Apache now has some of the infrastructure in place to
+      support serving multiple protocols. mod_echo has been written
+      as an example.</dd>
+
+      <dt><strong>Better support for non-Unix
+      platforms</strong></dt>
+
+      <dd>Apache 2.0 is faster and more stable on non-Unix
+      platforms such as BeOS, OS/2, and Windows. With the
+      introduction of platform-specific <a
+      href="mpm.html">multi-processing modules</a> (MPMs) and the
+      Apache Portable Runtime (APR), these platforms are now
+      implemented in their native API, avoiding the often buggy and
+      poorly performing POSIX-emulation layers.</dd>
+
+      <dt><strong>New Apache API</strong></dt>
+
+      <dd>The API for modules has changed significantly for 2.0.
+      Many of the module-ordering/-priority problems from 1.3 should
+      be gone. 2.0 does much of this automatically, and module ordering
+      is now done per-hook to allow more flexibility. Also, new calls
+      have been added that provide additional module capabilities
+      without patching the core Apache server.</dd>
+
+      <dt><strong>IPv6 Support</strong></dt>
+
+      <dd>On systems where IPv6 is supported by the underlying
+      Apache Portable Runtime library, Apache gets IPv6 listening
+      sockets by default. Additionally, the <directive
+      module="mpm_common">Listen</directive>, <directive module="core"
+      >NameVirtualHost</directive>, and <directive module="core"
+      >VirtualHost</directive> directives support
+      IPv6 numeric address strings (e.g., "Listen
+      [fe80::1]:8080").</dd>
+
+      <dt><strong>Filtering</strong></dt>
+
+      <dd>Apache modules may now be written as filters which act on
+      the stream of content as it is delivered to or from the
+      server. This allows, for example, the output of CGI scripts
+      to be parsed for Server Side Include directives using the
+      INCLUDES filter in mod_include.</dd>
+
+      <dt><strong>Multilanguage Error Responses</strong></dt>
+
+      <dd>Error response messages to the browser are now provided in 
+      several languages, using SSI documents. They may be customized 
+      by the administrator to achieve a consistent look and feel.</dd>
+
+      <dt><strong>Simplified configuration</strong></dt>
+
+      <dd>Many confusing directives have been simplified. The often
+      confusing Port and BindAddress directives are gone; only the
+      Listen directive is used for IP address binding; the
+      ServerName directive specifies the server name and port number
+      only for redirection and vhost recognition.</dd>
+
+      <dt><strong>Native Windows NT Unicode Support</strong></dt>
+
+      <dd>Apache 2.0 on Windows NT now uses utf-8 for all filename
+      encodings. These directly translate to the underlying Unicode
+      file system, providing multilanguage support for all Windows 
+      NT-based installations, including Windows 2000 and Windows XP.
+      <em>This support does not extend to Windows 95, 98 or ME, which 
+      continue to use the machine's local codepage for filesystem 
+      access.</em></dd>

+  <section id="module">
+    <title>Module Enhancements</title>
+
+    <dl>
+      <dt><strong>mod_ssl</strong></dt>
+
+      <dd>New module in Apache 2.0. This module is an interface
+      to the SSL/TLS encryption protocols provided by
+      OpenSSL.</dd>
+
+      <dt><strong>mod_dav</strong></dt>
+
+      <dd>New module in Apache 2.0. This module implements the HTTP
+      Distributed Authoring and Versioning (DAV) specification for
+      posting and maintaining web content.</dd>
+
+      <dt><strong>mod_auth_digest</strong></dt>
+
+      <dd>Includes additional support for session caching across
+      processes using shared memory.</dd>
+
+      <dt><strong>mod_charset_lite</strong></dt>
+
+      <dd>New module in Apache 2.0. This experimental module allows
+      for character set translation or recoding.</dd>
+
+      <dt><strong>mod_file_cache</strong></dt>
+
+      <dd>New module in Apache 2.0. This module includes the
+      functionality of mod_mmap_static in Apache 1.3, plus adds
+      further caching abilities.</dd>
+
+      <dt><strong>mod_headers</strong></dt>
+
+      <dd>This module is much more flexible in Apache 2.0. It can
+      now modify request headers used by mod_proxy, and it can
+      conditionally set response headers.</dd>
+
+      <dt><strong>mod_proxy</strong></dt>
+
+      <dd>The proxy module has been completely rewritten to take advantage
+      of the new filter infrastructure and to implement a more
+      reliable, HTTP/1.1 compliant proxy. In addition, new
+      &lt;Proxy&gt; configuration sections provide more readable
+      (and internally faster) control of proxied sites; overloaded 
+      &lt;Directory "proxy:..."&gt; configuration are not supported. The
+      module is now divided into specific protocol support modules 
+      including proxy_connect, proxy_ftp and proxy_http.</dd>
+
+      <dt><strong>mod_negotiation</strong></dt>
+
+      <dd>A new <directive module="mod_negotiation"
+      >ForceLanguagePriority</directive> directive can be used to assure that
+      the client receives a single document in all cases, rather than
+      NOT ACCEPTABLE or MULTIPLE CHOICES responses. In addition, the
+      negotiation and MultiViews algorithms have been cleaned up to
+      provide more consistent results and a new form of type map that
+      can include document content is provided.</dd>
+
+      <dt><strong>mod_autoindex</strong></dt>
+
+      <dd>Autoindex'ed directory listings can now be configured to 
+      use HTML tables for cleaner formatting, and allow finer-grained
+      control of sorting, including version-sorting, and wildcard
+      filtering of the directory listing.</dd>
+
+      <dt><strong>mod_include</strong></dt>
+
+      <dd>New directives allow the default start and end tags for SSI elements
+      to be changed and allow for error and time format configuration
+      to take place in the main configuration file rather than in the
+      SSI document. Results from regular expression parsing and grouping
+      (now based on Perl's regular expression syntax) can be retrieved
+      using mod_include's variables $0 .. $9.</dd>
+
+      <dt><strong>mod_auth_dbm</strong></dt>
+
+      <dd>Now supports multiple types of DBM-like databases using the
+      <directive module="mod_auth_dbm">AuthDBMType</directive>
+      directive.</dd>
+
+      <dt><strong>mod_auth_db</strong></dt>
+
+      <dd>Has been removed in favor of mod_auth_dbm with the AuthDBMType
+      directive.</dd>
+    </dl>
