+      <li>
+        <p>General improvements:</p>
+        <ul>
+          <li>
+            <p>Added experimental https inspection support which allows to filter https traffic. To enable it, install
+            MbedTLS and configure with --with-mbedtls, or install OpenSSL or LibreSSL and configure with
+            --with-openssl. Afterwards configure the directives in section 7 of the config file and enable the
+            +https-inspection action. Initial MbedTLS-based code contributed by Vaclav Svec, initial OpenSSL support
+            contributed by Maxim Antonov. With help from Nedzad Hrnjica and Ho+ Ho+ Ho+. Integration and improvements
+            sponsored by Robert Klemme.</p>
+          </li>
+          <li>
+            <p>pcrs: Request JIT compilation if it's supported and the filter isn't dynamic. This can speed up
+            filtering.</p>
+          </li>
+          <li>
+            <p>Added support for Brotli decompression. Sponsored by: Robert Klemme</p>
+          </li>
+          <li>
+            <p>Added FEATURE_EXTENDED_STATISTICS to gather statistics for block reasons and filter executions. To
+            enable it, configure with --enable-extended-statistics and visit http://config.privoxy.org/show-status.
+            Sponsored by: Robert Klemme</p>
+          </li>
+          <li>
+            <p>Use the IP_FREEBIND socket option, if defined. This allows Privoxy to bind to not-yet assigned IP
+            addresses which is useful in failover environments. Patch by Sam Varshavchik.</p>
+          </li>
+          <li>
+            <p>Allow to use extended host patterns and vanilla host patterns at the same time by prefixing extended
+            host patterns with "PCRE-HOST-PATTERN:". To enable this, configure with --enable-pcre-host-patterns.
+            Sponsored by: Robert Klemme</p>
+          </li>
+          <li>
+            <p>Added "Cross-origin resource sharing" (CORS) support. This allows to access Privoxy's CGI interface via
+            JavaScript from another domain (white-listed with the new cors-allowed-origin directive). Based on a patch
+            by Nedzad Hrnjica. Sponsored by: Robert Klemme.</p>
+          </li>
+          <li>
+            <p>Add SOCKS5 username/password support. Based on a patch by Sam, improved by Ivan Romanov. Closes
+            Patch#141 and solves TODO#105.</p>
+          </li>
+          <li>
+            <p>Bump the maximum number of action and filter files to 100 each. Sponsored by: Robert Klemme</p>
+          </li>
+          <li>
+            <p>Fixed handling of filters with "split-large-forms 1" when using the CGI editor. Reported by withoutname
+            in #921.</p>
+          </li>
+          <li>
+            <p>Better detect a mismatch of connection details when figuring out whether or not a connection can be
+            reused.</p>
+          </li>
+          <li>
+            <p>Don't send a "Connection failure" message instead of the "DNS failure" message. Sponsored by: Robert
+            Klemme</p>
+          </li>
+          <li>
+            <p>Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted requests were only logged with
+            LOG_LEVEL_REQUEST when they weren't crunched (in which case they were logged with LOG_LEVEL_CRUNCH). This
+            was documented behaviour, but logging all requests seems more useful.</p>
+          </li>
+          <li>
+            <p>Fixed locking around localtime() and gmtime().</p>
+          </li>
+          <li>
+            <p>Removed OS/2 support. We haven't provided OS/2 packages in years, it complicated the code and it
+            depended on a fallback snprintf() implementation which is GPLv2 only.</p>
+          </li>
+          <li>
+            <p>Remove the fallback snprintf() implementation Now that OS/2 support is gone we no longer need it.</p>
+          </li>
+          <li>
+            <p>Fixed a bunch of format specifiers log messages.</p>
+          </li>

+      <h2 class="SECT2"><a name="UPGRADERSNOTE" id="UPGRADERSNOTE">3.1. Note to Upgraders</a></h2>
+      <p>A quick list of things to be aware of before upgrading from earlier versions of <span class=
+      "APPLICATION">Privoxy</span>:</p>
+      <ul>
+        <li>
+          <p>The recommended way to upgrade <span class="APPLICATION">Privoxy</span> is to backup your old
+          configuration files, install the new ones, verify that <span class="APPLICATION">Privoxy</span> is working
+          correctly and finally merge back your changes using <span class="APPLICATION">diff</span> and maybe
+          <span class="APPLICATION">patch</span>.</p>
+          <p>There are a number of new features in each <span class="APPLICATION">Privoxy</span> release and most of
+          them have to be explicitly enabled in the configuration files. Old configuration files obviously don't do
+          that and due to syntax changes using old configuration files with a new <span class=
+          "APPLICATION">Privoxy</span> isn't always possible anyway.</p>
+        </li>
+        <li>
+          <p>Note that some installers remove earlier versions completely, including configuration files, therefore you
+          should really save any important configuration files!</p>
+        </li>
+        <li>
+          <p>On the other hand, other installers don't overwrite existing configuration files, thinking you will want
+          to do that yourself.</p>
+        </li>
+        <li>
+          <p>In the default configuration only fatal errors are logged now. You can change that in the <a href=
+          "config.html#DEBUG">debug section</a> of the configuration file. You may also want to enable more verbose
+          logging until you verified that the new <span class="APPLICATION">Privoxy</span> version is working as
+          expected.</p>
+        </li>
+        <li>
+          <p>Three other config file settings are now off by default: <a href=
+          "config.html#ENABLE-REMOTE-TOGGLE">enable-remote-toggle</a>, <a href=
+          "config.html#ENABLE-REMOTE-HTTP-TOGGLE">enable-remote-http-toggle</a>, and <a href=
+          "config.html#ENABLE-EDIT-ACTIONS">enable-edit-actions</a>. If you use or want these, you will need to
+          explicitly enable them, and be aware of the security issues involved.</p>
