PIX IOS 7.X Version comparison?

Cisco seldom produces an itemized list of differences between versions, and as far as I know there is no electronic tool for this purpose.

The closest you get is the release notes, which briefly describe the major changes, and which often offer long list of bug fixes. Especially in 7.x so far, it isn't uncommon for the difference between versions to consist almost entirely of bug fixes.

Thanks!

Is there a preferred version to run then? I just Upgraded from 6.3 to

I haven't figured out yet why they released 7.1. My speculation had been that it would be for a soon-to-be-announced new device, but that hasn't materialized. My next best guess is that it has something to do with PIX vs ASA, but I can't tell from the release notes.

I would suggest that this is a situation in which you should open a TAC case and ask about the difference. [I've shifted out of the networking side at work, so I don't have a TAC account now.]

Thanks! I'll let you know what they say.
