Facebook has unveiled its new site design, described by the social network site as cleaner and simpler.
Users are also being given the chance to try out a host of new features.
In the course of testing the new site, Facebook was hit with a data breach, which saw users' dates of births inadvertently revealed. Such information can be useful for identity thieves. This bug has now been ironed out.
The company is inviting people to use the new design and try out the improved features by navigating back and forth between the new and current versions of the site.
Access to the new design will be limited at first, and will gradually become available to all of Facebook's 80 million-plus users over the coming days.
Facebook is using the new design to provide more feature-rich "walls" to users, invite them to post more content, and benefit from easier navigation.
