It looks like Apple's getting another fix in before Lion slinks on to the scene. Mac OS X 10.6.8 is now available for download, and brings with it a number of "general operating system fixes," including further support for IPv6, improved VPN reliability, and removal of known variants of Mac Defender. It also promises to fix a glitch that has Preview randomly shutting down, and will get the App Store ready to roar for when Lion lands on the scene. We're getting it going on our laptop at home. If you've done the same, let us know how it's working out for you.
