Mac OS X 10.5.4 Released
This morning I updated to 10.5.4 on my MacBook Pro. There are security fixes in Safari, a few things for Safari, and a few things for the new MobileMe (was (dot)Mac) and the iPhone Store in iTunes. I was pleased that they put in the fix for Spaces and the Finder window focus, but I'm not sure if the faster Javascript engine is in Safari now, or if that's targeted for a later release.
I'll have to update my iMac and the kids' MacBooks one of these evenings, or this weekend. I'm not sure they'll see any difference - I haven't yet, but for all the web surfing they do, the added security fixes will be a very good thing.
