-><P
-> <SPAN
-CLASS="APPLICATION"
->Privoxy 3.0.17</SPAN
-> is a stable release.
- The changes since 3.0.16 stable are:</P
-><P
-> <P
-></P
-><UL
-><LI
-><P
->    Fixed last-chunk-detection for responses where the content was small
-    enough to be read with the body, causing Privoxy to wait for the
-    end of the content until the server closed the connection or the
-    request timed out. Reported by "Karsten" in #3028326.
-   </P
-></LI
-><LI
-><P
->    Responses with status code 204 weren't properly detected as body-less
-    like RFC2616 mandates. Like the previous bug, this caused Privoxy to
-    wait for the end of the content until the server closed the connection
-    or the request timed out. Fixes #3022042 and #3025553, reported by a
-    user with no visible name. Most likely also fixes a bunch of other
-    AJAX-related problem reports that got closed in the past due to
-    insufficient information and lack of feedback.
-   </P
-></LI
-><LI
-><P
->    Fixed an ACL bug that made it impossible to build a blacklist.
-    Usually the ACL directives are used in a whitelist, which worked
-    as expected, but blacklisting is still useful for public proxies
-    where one only needs to deny known abusers access.
-   </P
-></LI
-><LI
-><P
->    Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
-    network. This should make debugging various parsing issues a lot easier.
-   </P
-></LI
-><LI
-><P
->    The IPv6 code is enabled by default on Windows versions that support it.
-    Patch submitted by oCameLo in #2942729.
-   </P
-></LI
-><LI
-><P
->    In mingw32 versions, the user.filter file is reachable through the
-    GUI, just like default.filter is. Feature request 3040263.
-   </P
-></LI
-><LI
-><P
->    Added the configure option --enable-large-file-support to set a few
-    defines that are required by platforms like GNU/Linux to support files
-    larger then 2GB. Mainly interesting for users without proper logfile
-    management.
-   </P
-></LI
-><LI
-><P
->    Logging with "debug 16" no longer stops at the first nul byte which is
-    pretty useless. Non-printable characters are replaced with their hex value
-    so the result can't span multiple lines making parsing them harder then
-    necessary.
-   </P
-></LI
-><LI
-><P
->    Privoxy logs when reading an action, filter or trust file.
-   </P
-></LI
-><LI
-><P
->    Fixed incorrect regression test markup which caused a test in
-    3.0.16 to fail while Privoxy itself was working correctly.
-    While Privoxy accepts hide-referer, too, the action name is actually
-    hide-referrer which is also the name used one the final results page,
-    where the test expected the alias.
-   </P
-></LI
-><LI
-><P
->    CGI interface improvements:
-    <P
-></P
-><UL
-><LI
-><P
->      In finish_http_response(), continue to add the 'Connection: close'
-      header if the client connection will not be kept alive.
-      Anonymously pointed out in #2987454.
-     </P
-></LI
-><LI
-><P
->      Apostrophes in block messages no longer cause parse errors
-      when the blocked page is viewed with JavaScript enabled.
-      Reported by dg1727 in #3062296.
-     </P
-></LI
-><LI
-><P
->      Fix a bunch of anchors that used underscores instead of dashes.
-     </P
-></LI
-><LI
-><P
->      Allow to keep the client connection alive after crunching the previous request.
-      Already opened server connections can be kept alive, too.
-     </P
-></LI
-><LI
-><P
->      In cgi_show_url_info(), don't forget to prefix URLs that only contain
-      http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
-     </P

-     </P

+      </h1>
+      <p>
+        <span class="APPLICATION">Privoxy 3.0.17</span> is a stable release.
+        The changes since 3.0.16 stable are:
+      </p>
+      <p>
+      </p>
+      <ul>
+        <li>
+          <p>
+            Fixed last-chunk-detection for responses where the content was
+            small enough to be read with the body, causing Privoxy to wait
+            for the end of the content until the server closed the connection
+            or the request timed out. Reported by "Karsten" in #3028326.
+          </p>
+        </li>
+        <li>
+          <p>
+            Responses with status code 204 weren't properly detected as
+            body-less like RFC2616 mandates. Like the previous bug, this
+            caused Privoxy to wait for the end of the content until the
+            server closed the connection or the request timed out. Fixes
+            #3022042 and #3025553, reported by a user with no visible name.
+            Most likely also fixes a bunch of other AJAX-related problem
+            reports that got closed in the past due to insufficient
+            information and lack of feedback.
+          </p>
+        </li>
+        <li>
+          <p>
+            Fixed an ACL bug that made it impossible to build a blacklist.
+            Usually the ACL directives are used in a whitelist, which worked
+            as expected, but blacklisting is still useful for public proxies
+            where one only needs to deny known abusers access.
+          </p>
+        </li>
+        <li>
+          <p>
+            Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from
+            the network. This should make debugging various parsing issues a
+            lot easier.
+          </p>
+        </li>
+        <li>
+          <p>
+            The IPv6 code is enabled by default on Windows versions that
+            support it. Patch submitted by oCameLo in #2942729.
+          </p>
+        </li>
+        <li>
+          <p>
+            In mingw32 versions, the user.filter file is reachable through
+            the GUI, just like default.filter is. Feature request 3040263.
+          </p>
+        </li>
+        <li>
+          <p>
+            Added the configure option --enable-large-file-support to set a
+            few defines that are required by platforms like GNU/Linux to
+            support files larger then 2GB. Mainly interesting for users
+            without proper logfile management.
+          </p>
+        </li>
+        <li>
+          <p>
+            Logging with "debug 16" no longer stops at the first nul byte
+            which is pretty useless. Non-printable characters are replaced
+            with their hex value so the result can't span multiple lines
+            making parsing them harder then necessary.
+          </p>
+        </li>
+        <li>
+          <p>
+            Privoxy logs when reading an action, filter or trust file.
+          </p>
+        </li>
+        <li>
+          <p>
+            Fixed incorrect regression test markup which caused a test in
+            3.0.16 to fail while Privoxy itself was working correctly. While
+            Privoxy accepts hide-referer, too, the action name is actually
+            hide-referrer which is also the name used one the final results
+            page, where the test expected the alias.
+          </p>
+        </li>
+        <li>
+          <p>
+            CGI interface improvements:
+          </p>
+          <ul>
+            <li>
+              <p>
+                In finish_http_response(), continue to add the 'Connection:
+                close' header if the client connection will not be kept
+                alive. Anonymously pointed out in #2987454.
+              </p>
+            </li>
+            <li>
+              <p>
+                Apostrophes in block messages no longer cause parse errors
+                when the blocked page is viewed with JavaScript enabled.
+                Reported by dg1727 in #3062296.
+              </p>
+            </li>
+            <li>
+              <p>
+                Fix a bunch of anchors that used underscores instead of
+                dashes.
+              </p>
+            </li>
+            <li>
+              <p>
+                Allow to keep the client connection alive after crunching the
+                previous request. Already opened server connections can be
+                kept alive, too.
+              </p>
+            </li>
+            <li>
+              <p>
+                In cgi_show_url_info(), don't forget to prefix URLs that only
+                contain http:// or https:// in the path. Fixes #2975765
+                reported by Adam Piggott.
+              </p>
+            </li>
+            <li>
+              <p>
+                Show the 404 CGI page if cgi_send_user_manual() is called
+                while local user manual delivery is disabled.
+              </p>
+            </li>
+          </ul>
+        </li>
+        <li>
+          <p>
+            Action file improvements:
+          </p>
+          <ul>
+            <li>
+              <p>
+                Enable user.filter by default. Suggested by David White in
+                #3001830.
+              </p>
+            </li>
+            <li>
+              <p>
+                Block .sitestat.com/. Reported by johnd16 in #3002725.

+              </p>
+            </li>
+            <li>
+              <p>
+                Remove the too broad yahoo section, only keeping the
+                fast-redirects exception as discussed on ijbswa-devel@.
+              </p>
+            </li>
+            <li>
+              <p>
+                Don't block adesklets.sourceforge.net. Reported in #2974204.
+              </p>
+            </li>

+              </p>
+            </li>
+            <li>

+                Don't handle view.atdmt.com as image. It's used for
+                click-throughs so users should be able to "go there anyway".
+                Reported by Adam Piggott in #2975927.
+              </p>
+            </li>
+            <li>
+              <p>
+                Also let the refresh-tags filter remove invalid refresh tags
+                where the 'url=' part is missing. Anonymously reported in
+                #2986382. While at it, update the description to mention the
+                fact that only refresh tags with refresh times above 9
+                seconds are covered.
+              </p>
+            </li>
+            <li>
+              <p>
+                javascript needs to be blocked with +handle-as-empty-document
+                to work around Firefox bug 492459. So move .js blockers from
+                +block{Might be a web-bug.} -handle-as-empty-document to
+                +block{Might be a web-bug.} +handle-as-empty-document.
+              </p>
+            </li>

+            <li>

+                with default pre-settings. If you change the configuration to
+                block cookies by default, you'll need additional exceptions.
+                Reported by Mathias Homann in #3101419 and by Patrick on
+                ijbswa-users@.
+              </p>
+            </li>
+          </ul>
+        </li>
+        <li>
+          <p>
+            Documentation improvements:
+          </p>
+          <ul>

+                Explicitly mention how to match all URLs.

+            </li>
+            <li>
+              <p>
+                Consistently recommend socks5 in the Tor FAQ entry and

+              </p>
+            </li>
+            <li>
+              <p>
+                Turn http_response.reason into an enum and rename it to
+                http_response.crunch_reason.
+              </p>
+            </li>
+            <li>
+              <p>
+                Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686
+                GNU/Linux.
+              </p>
+            </li>
+            <li>
+              <p>
+                Fix white-space in a log message in
+                remove_chunked_transfer_coding(). While at it, add a note
+                that the message doesn't seem to be entirely correct and
+                should be improved later on.
+              </p>
+            </li>
+          </ul>

+          <p>
+            GNUmakefile improvements:
+          </p>
+          <ul>
+            <li>
+              <p>
+                Use $(SSH) instead of ssh, so one only needs to specify a
+                username once.
+              </p>
+            </li>
+            <li>
+              <p>
+                Removed references to the action feedback thingy that hasn't
+                been working for years.
+              </p>
+            </li>
+            <li>
+              <p>
+                Consistently use shell.sourceforge.net instead of
+                shell.sf.net so one doesn't need to check server fingerprints
+                twice.
+              </p>
+            </li>
+            <li>
+              <p>
+                Removed GNUisms in the webserver and webactions targets so
+                they work with standard tar.
+              </p>
+            </li>

+          <a name="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>
+        <p>
+        </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>
+              <tt class="FILENAME">standard.action</tt> has been merged into
+              the <tt class="FILENAME">default.action</tt> file.
+            </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.
