* New upstream release (SVN rev 9377)
   o Fixes many bugs concerning PDF rendering, to make the PDF printing
     workflow correctly working.
   o Fixes long-standing bugs in many drivers, like input paper tray and
     duplex options not working for the built-in PCL 4, 5, 5c, 5e, and
     6/XL drivers, PDF input not working for bjc600, bjc800, and cups
     output devices, several options not working and uninitialized
     memory with cups output device.
   o Merged nearly all patches of the Ubuntu and Debian packages upstream.
   o Fixes LP: #317810, LP: #314439, LP: #314018.

79

80
 *
 
81
 *    Releasing the gs_ht structure will NOT release the client data
