High fives all round for Safari 5, the newest version of Apple's Web browser. As steals the headlines, Safari 5 gets extensions, more HTML5 goodness, and ad-free reading of articles.
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.
