Fine and useful options, all in a translucent look like interface

Hi !
It is said about the new version (v1.3.6) :
" - Removed QuickTime decoder. (FFmpeg decoder only) "

Im wondering why ? What does this mean ? Will there be some kind of shortage if FFmpeg decoder is not included anymore ?
I hesitate before updating to this new version.

Your soft has so many advantages, anyway…
Like a jewelry… supported by plenty of discrete useful options !
Elegant and relaxing !
Thanks.
