- Please use this to report such configuration related problems as missed
- ads, sites that don't function properly due to one action or another,
- innocent images being blocked, etc.
+> Parts of Privoxy have been refactored to increase maintainability.
</P
></LI
><LI
><P
-> In addition, there are numerous bug fixes and significant enhancements,
- including error pages should no longer be cached if the problem is fixed,
- much better DNS error handling, various logging improvements, and

- Some installers may remove earlier versions completely, including
- configuration files. Save any important configuration files!
+> 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

- On the other hand, other installers may not overwrite any existing configuration
- files, thinking you will want to do that. You may want to manually check
- your saved files against the newer versions to see if the improvements have
- merit, or whether there are new options that you may want to consider.
- There are a number of new features, but most won't be available unless
- these features are incorporated into your configuration somehow.
+> 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.
