  Version 7  27-Jun-2009
  ----------------------
  
 -cjpeg now supports scalings 8/N with all N from 1 to 16.
 -Scaled DCTs with size larger than 8 are now also used for resolving the
 -common 2x2 chroma subsampling case without additional spatial resampling.
 -Separate spatial resampling for those kind of files is now only necessary
 -for N>8 scaling cases.
 -Furthermore, separate scaled DCT functions are provided for direct resolving
 -of the common asymmetric subsampling cases (2x1 and 1x2) without additional
 -spatial resampling.
+ New scaled DCTs implemented.
+ djpeg now supports scalings N/8 with all N from 1 to 16.
+ 
  cjpeg -quality option has been extended for support of separate quality
  settings for luminance and chrominance (or in general, for every provided
  quantization table slot).
