+> 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.
