<h3 id="new">New in DP2</h3>



<ul>

  <li>Platform support for Vulkan, a new 3D rendering API that provides

  explicit, low-overhead GPU (Graphics Processor Unit) control and offers

  improved performance for draw-call heavy applications. For details, see the

  <a href="{@docRoot}ndk/guides/graphics/index.html">documentation</a>.

  </li>



  <li>New people emoji with support for skin tones, and new Unicode 9 glyphs.

  Skin tone and new emoji will not show up until keyboards build support for

  them in the palette. Apps should not need to take any action to take

  advantage of these new emoji, unless the apps use a non-system font. IME

  developers need to incorporate support for the new emoji.
