  64.  * on valid packets.  Those commands have been added.

    66. 

  66.  * The semantics of Variation 0 have been cleaned up.  Variation 0 is the
    67. 

  67.  * "Default Variation".  It is used only in Master -> Slave read commands
    68. 

  68.  * to request the data in whatever variation the Slave is configured to use by
    69. 

  69.  * default. Decoder strings have been added to the Binary Output and
    70. 

  70.  * Analog Output objects (10 and 40) so that group read commands will
    71. 

  71.  * decode properly.
