- 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.
+> The client socket is kept open until the server socket has
+ been marked as unused. This should increase the chances that
+ the still-open connection will be reused for the client's next
+ request to the same destination. Note that this only matters
+ if connection-sharing is enabled.

-> In addition, there are various bug fixes and significant enhancements, including
- error pages should no longer be cached if the problem is fixed, better DNS
- error handling, and various logging improvements.

+ volunteers a better idea of what the current goals are. Donations

->
- 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
+CLASS="APPLICATION"
+>diff</SPAN
+> and maybe <SPAN
+CLASS="APPLICATION"
+>patch</SPAN
+>.

><P
->
- On the other hand, some 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.
