New features and changes

 * A prototype of the Phodeo feature is included in this build.
 * A new Communication History shell folder is also implemented.

Bugs

 * For all its instabilities, although this build's Desktop Composition Engine can show the Aero borders, it tends to be extremely buggy easily after a while.

Installation
Some copies of this build's installation media cannot be booted normally due to a call to a non-existent index in the  by. To install this build in this case, either upgrade from a previous build or use a WinPE from a previous build.
