Improvements:
- Improved processing speed by optimizing sorting algorithms to each use. This work was done by Emmanuel Brandt who spend a large amount of his time to provide the best compromise between speed and performances.
- Improved free disk space feedback and checks before running preprocess, global registration and up-scaling at stacking
- Improved mouse selection by making it more dynamic
- Taking into account the Bayer matrix offset keywords from FITS headers
- Displaying script line when error occurs
