Well, 10.5.7 update just dropped Tuesday!
Many apps were updated including Time Machine, Address Book, and iCal. For Safari Beta 4 users, however, you need to update twice.
After the initial update (and it’s a big one!) reboot, and run Software Updater again. You’ll notice a security update to Safari 4 Beta.
As usual, it seems to be one of Apple’s general “security and vulnerability,” updates. Your guess on those patches is as good as mine. Correction! Apple talks about what got updated in Safari 4 Beta here.
It’s interesting that they even include a Beta’s update in the 10.5.7 update in the first place. I guess enough people are using it that it was a good idea.
Good Luck!
