Safari 3.1 is a 39MB update that's available from Apple's product page. It requires a restart and shows a build number of 5525.13 in the About box.
I haven't had a chance to test it with all my sites yet, but let's hope that Safari 3.1 alleviates some browser gymnastics that I blogged about on Sunday.
Safari 3.1 scores a 75/100 on the Acid 3 test:
The Acid 3 test is far more complex than the Acid 2 test. It covers a wider range of standards and consists of many more individual tests. Browsers have to render a sequence of boxes that display dynamically in a stairstep pattern. For every cluster of tests passed successfully, the boxes will fill in with a color, which signifies that all of the tests covered by that block have passed.
If you run Acid 3 on the shipping versions of current browsers (Firefox 2, Safari 3, Opera 9, IE7), you’ll see that they all score quite low. For example Safari 3 scores a 39/100. This percentage score is a bit misleading however. The situation with all four browser engines really isn’t that bad.
You can think of the Acid 3 test as consisting of 100 individual test suites. In order for a browser engine to claim one of these precious 100 points, it has to pass a whole battery of tests around a specific standard. In other words it’s like the browser is being asked to take 100 separate exams and score an A+ on each test in order to get any credit at all.
The reality is that all of the browsers are doing much better than their scores would have you believe, since the engines are often passing a majority of the subtests and experiencing minor failures that cost them the point for that section.
