Split Choice
As it stands, users will still need to make a choice between Squid-3.0 and Squid-2.7 when moving away from Squid-2.5 and Squid-2.6. This decision needs to be made on the basis of their feature needs.
The only help we can provide for this is to point out that:
Squid-3.0 has been largely sponsored by the Web-Filtering user community. With features aimed at adapting and altering content in transit.
Squid-2.7 has been largely sponsored by high-performance user community. With features aimed at Caching extremely high traffic volumes in the order of Terabytes per day.
