Safari 3.1 released – HTML 5 CSS Animations

There are a bunch of improvements listed, including support for HTML 5 specs and CSS Animations, but my two favorites are “Stability: Improves Stability” and “Compatibility: Improves Compatibility”. The Leopard version weighs in around 35 MB, while the Tiger is a slim and trim 25.7 MB.

So, does anyone else find it odd a Safari point release requires a restart? Oh well. There goes my 38 days of uptime on my MacBook.

    It requires a restart because the update most likely alters Webkit, which is a framework of OSX.

    Actually, it did give you a heads up about requiring a reboot before you downloaded it. Notice that in the screenshot you provided in this article there is an arrow to the left of the list item and that the arrow is described below, saying “Restart will be required.” Apple can lead the horse to water…

  3. The user agent string in the develop menu should be handy. Finally can access those pesky banking sites.

    Those are some significant changes. They’re really making a push to make this an optimal browser.

    Does this update include the increased speed that people were reporting in the latest webkit build?

    it breaks the ‘v’ key when using google reader, which makes this upgrade more of a downgrade for me (since i spend about 50% of my time in safari on that one site).

  6. See that little white triangle inside the grey box? You know, the one next the to the install tickbox?

    That means it needs a restart, and you get that BEFORE clicking the ‘Install 1 item’ button.

    Just thought I’d point that out 🙂

    Your welcome, by the way.

    We can make it faster, better than it was before, the Bionic Browser. It is pretty darn quick. Now let’s see if it will load eBay pages consistently.

    Before installing know that 3rd party InputManager items may prove incompatible with the latest Safari version. Within a week upgraded versions will be released. This includes SAFT, PicLens etc. If you have already installed Safari 3.1, remove the aforementioned items from your Library>InputManagers folder. Otherwise, you may have problems starting Safari, or seeing stability.

    I don’t believe you can reinstall Safari 3.0.4, as WebKit changes make this a no go. You would need to reinstall OS X first to revert back to the earlier webkit.
