1) quantization stepsizes stored as float instead of shifted integers -> fixes a pb of precision when using very small stepsizes. 2) bug fixed when decoding until bitplane 0 -> r-value (1/2) added to the coefficient.

* Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the command line when encoding an image generates layers with the corresponding psnr. You have to specify values in the increase order. This option is incompatible with "-r" or "-f" options.
...
* Old -q option is now available with -f
* The INDEX-file structure has been modified and is now like this :
------------------------------
image_width image_height

nb_tiles_width nb_tiles_height
nb_components
nb_layers
nb_decompositions
