The release, which underwent private testing this week, will tie in a number of other enhancements, most of which have been under constant development as part of the company's WebKit open source application framework since last fall. They aim to provide Web developers a means of writing more dynamic and customizable web pages and iPhone apps, which will in turn provide surfers with a more feature-rich and enjoyable experience.
Another significant addition to Safari 3.1 will be support of HTML5's SQL storage application programming interface (API), which is a client-side database storage programming interface that will allow a future array of web applications to store structured data locally on a user's machine using SQL. The API is asynchronous, according to Apple, and uses callback functions to track the results of a database query.
Also on tap for the new version of the Apple browser is support for video and audio tags as outlined in the draft specification of HTML5, which add native support for embedding video and audio content in web pages. Additionally, they provide a rich scripting (API) that will allow developers tailor playback controls.
