Most things are unchanged from version 5.0.2.  However, some fixes have
been made and those are listed here.

1.  Further changes to the OVERRUN and CHECK_CONDITION code to fix problems
   with the ZIP disks.  Also fixed a generic bug in the code that
   generates REQUEST_SENSE commands.

2.  Fixes for devices that are broken in regards to tagged queueing.

Other stuff as well, but that's the highlights.
