Introducing Android 4.3, a sweeter Jelly Bean : Official Announcement
Today we’re releasing Android 4.3 — an upgrade to Jelly Bean that introduces a number of new features, including restricted profiles. Android 4.3 also adds Bluetooth Smart support (a.k.a Bluetooth Low-Energy); the latest in 3D graphics through OpenGL ES 3.0; and more.
Restricted profiles for tablets
Lightweight and portable, tablets are perfect for sharing with others. Last October we added support for multiple users. Each person has a separate space and can freely customize the tablet experience, from lockscreen to wallpaper, apps and folders.
In Android 4.3, we’re introducing restricted profiles, which let you manage per-user access to apps and content. Restricted profiles can be used in any number of situations. For example, restricted profiles enable parental controls, so certain family members are prevented from accessing mature content. Alternately, retail stores can use tablets as kiosks that show product information, or shops can use tablets as point of sale systems, all while limiting access to apps.
