The Safari update in the Mac OS X 10.4.3 update passes the Acid2 Test. Congrats to the team on that effort. Hyatt originally noted the development on his blog back in April. This is the first official release that passes Acid2. The relevent Mozilla bug is #289480 (unnecessary comments in that bug will get you spanked; as timeless notes it’s just distracting).
The Safari blog is a great read for anyone interested in browsers, web development, or apple software development. Some great minds at work.
