due to the recently found security flaw, I need to upgrade my 3030 box (256 Megs of RAM) which is currently running 4.0.1. After figuring out that I need either 4.1.7E or 4.7, I checked the release notes. It seems to me that the new features in 4.7 only refer to WebVPN, Outlook Web Access, and CSD, all of which we don't use. The basic IPsec VPN functionality looks unchanged, so 4.1.7E might simply be the less disruptive change.
Any comments on this one?
