Comment 11 for bug 924739

Some options could be translated.
http://www.squid-cache.org/Doc/config/ shows what's compatible and what's not.

The release notes list which tags have been added, changed and removed. E.g.
header_access was replaced by request_header_access and reply_header_access so the one tag becomes two for more fine grained control.

A pointer to the Squid release notes is what Red Hat did for RHEL 6.0's notes:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Migration_Planning_Guide/ch04s12.html
And I think it was referenced elsewhere too.
