The coin is now called MIRAGE.  This is simply a name change (rebranding).  IT IS STILL THE SAME  COIN.  The new wallet and source code are available here: https://github.com/x3c/mirage/releases

PLEASE NOTE: the data directory changes from %appdata%\X3C to %appdata%\MIRAGE on Windows, and from ~/.X3C to ~/.MIRAGE on Linux
Please follow the following guide to migrate from the old wallet to the new one.  Remeber to make extensive backups of everything before attempting anything.   https://docs.google.com/document/d/1VSD0iIyGYy24wQYul2N8HAPnNpAL5hq8cfipMYsBW7s

STEX and other services will change the name from X3C to MIRAGE over the next few days.
