Shortly after the release of version 1.0.4, last week, we are forced to make a fix and release Siril 1.0.5 much earlier than expected. Indeed, we found a bug introduced in the previous version when we had fixed a bug. Sometimes, errors compensate and don’t show up, but when you fix one, the other one shows up. This is exactly what happened here. This bug is critical and causes a shift of 1 pixel in x and y after a registration of images on which there was a meridian flip.
