Advice on migration from Squid 2.2S5 to 2.3S1?

This is on a RedHat box, with Linux kernel v2.2.14. I've got Squid
configured to act as a transparent proxy.

Below are my changes from the default Squid v2.2S5 configuration. I
understand that I will need to add the filesystem type to the
"cache_dir" parameter, but beyond that, what needs to be changed?

I've been reading of problems with v2.3S1's internal DNS resolution.
Should I disable internat resolution and stay with the use of
dns_children?

Any advice on v2.2S5-->v2.3Sx migrations issues and gotchas will be
appreciated. Thanks.
