According to a post on the official Facebook Blog, the updated profile will be rolled out to other regions of the world “in the near future.”
The post says:
We announced timeline in September and made it available to developers building apps on our platform. Since then, more than one million people have signed up for the developer beta to access timeline. The feedback we’ve received so far has been invaluable. Starting today, we are making timeline more widely available as we measure speed and other types of performance. We’ll begin by making it available to people in New Zealand and then roll it out more broadly in the near future.
Readers, will you choose to upgrade to the new advanced profile when it becomes available in your region?
