  codebase were not compatible with TigerVNC.

TigerVNC 1.4.0 - Lots of changes have been made since
the last release, but the highlights are:

   longer run Xvnc in colour map mode.
 - Improvements to the keyboard handling both on the server and client
 - Support for newer Xorg versions in the server build
 - x0vncserver now supports XDamage for instant updates, making it
   slightly less useless

 - Improved TLS implementation in the Java client
 - Lots and lots of cleanups and bug fixes
