Safari 5 also cosies up to Microsoft, adding the Bing search engine as a built-in search option alongside Google and Yahoo. The address bar also autocompletes your typing to search any part of the Web addresses in your history and bookmarks, instead of just the start of each URL.
Update: Apple has told us that Safari 5 will include an extensions gallery for users to browse add-ons before downloading them from the developer's Web site. The gallery will open "in the summer". If you fancy making your own extension, sign up to the free Safari Developer Program and use the add-on builder within Safari.
HTML5 by five
HTML5 puts the 5 in Safari 5, so to speak, with new features including full-screen video and closed captioning. On the programming front there's support for assorted HTML tags, including sectioning elements, draggable attributes and forms validation. Safari 5 uses HTML5 to create separate pages in your history for dynamic Ajax-created pages, and supports upstream and downstream communication over a single connection with WebSocket. You'll be able to get EventSource push notifications, and access local services with geolocation. This lets you tell geolocation-enabled Web sites where you are for location-based services and content.
The new browser uses the DNS pre-fetching technique that helps make Chrome load pages faster. This looks at the links on a Web page and starts to work out the addresses it might need, before you even click them. Safari 5 also scores 100 out of 100 in the Acid3 rendering test.
Safari Reader banishes ads
The final new feature is Safari Reader. When it spots an article, a reader icon appears in the address bar. Click on it, and you get a floating box containing the text, pictures and links of the article without any ads. Articles can be printed or even emailed in full. It even pulls in the other pages of multi-page articles -- but not ours, it seems, sorry -- so you can read a whole story in one uninterrupted, clutter-free sitting.
Don't take our word for it -- try it yourself!
Safari 5 is free to download, and is available now at apple.com/safari.
