- Setting a null rotation with no crop (or passing the command `rotate 0 -nocrop`) would result in a crash. This has been fixed for next 1.0
- Polynomial background gradient removal had an issue with the degree where it was the degree minus 1 that was used. This has been fixed for next 1.0
- The area used for flat auto-normalization was wrong. This has been fixed for the next 1.0
- There was a problem in the GESDT pixel rejection algorithm, allowing an excluded cold pixel to make its way in the stack. This has been fixed for the next 1.0
- There was a 0.5 pixel offset in PSF coordinates, this has been fixed for the next 1.0
