Hi brothers.

I´m running Squid Cache: Version 3.0.STABLE8 over debian 6, and I´d like 
to get information about what is the advantage to update it to squid3.1 
to the latest vertsion and how can I achieve this mission. How to 
upgrade squid with out of loss of my old configuration?

Please somebody can throw me a bone here?


Thanks in advance
