  Hmm.. not a big work was made, but... a big problem was fixed.

  V0.9-pre8

  Yes, yes, yes you are right, this is a very bad release.
  This version  doesn't  have  eggs  crashed  on the lens, but i 
  think (hope) we are in the right way to get a working version.
  The  initialization  data  was  changed   to  reach  the  size 
  adjustable but the result isn't perfect.
  The half sizes (160x120 and 176x144) doesn't work.
  A lot of debug messages  was added for help users ( that saint 
  peolpe that want to crash his system) to discover bugs.
  And about the colors, ...well... bad news i think it will need
  a long time...
  Another think was added.... the best viewer for quickcams was
  modify only for the VC, it doesn't want to substiture the good
  work of the developers, but i need some specs for the the VC.

30 March 2001 
  V0.9-pre7

  Add and disabled the mmap feature until a YUV method coversion
  will be found for use with xawtv/like programs.
  A lot  of  research  to  get  RGB  components  was made and we
  reach a very bad colors but i think we are in the correct way.
  We loose a lot of time thinking about a YCrCb -> RGB converter
  but  colors  seems  to  be  in  plained  mode,  with some bits 
  are exchanged.
  Brightness and exposure time was adjusted,  but exposure  time
  value need to be converted in a math function.
  Jonathan Guthrie submit a patch for use the driver with 2.2.19 
  kernel.
