- New astrometry annotation and object searching features
- New snapshot feature
- Refactoring of the conversion internal algorithm, can convert any sequence to any other sequence type
- Refactoring of the sequence export with many fixes
- New ability to exclude sequence frames from the Plot tab
- New merge command that merges sequences
- New seqstat command that computes statistics on a sequence
- Displaying pixel world coordinates at the bottom of the image
- Improved colour saturation tool with a background factor to adjust the strength
- Reduced the memory used by global registration
- Improved FITS image reading time
- Improving support for films (AVI and others) as sequence: notifying the user, suggesting conversion, fixing parallel operations (should not crash any more)
- Reduced minimal window size
- Add rejection type parameters the stack command
- Improve font adaptation to various screen resolutions
- Fixed sequence analysis of PSF (seqpsf) for 32-bit images and for sequences with no registration data
- Fixed out-of-memory conditions on global registration and median or mean stacking (caused some systems to freeze)
- Fixed memory limits for 32-bit siril on 64-bit OS (available memory becomes 2GB) and fixed opening of large SER files for 32-bit siril
- Fixed minimum and maximum stacking which were broken for RGB sequences
- Fixed the setref command to work without an opened sequence
- Fixed a crash in plate solving on second try and improve its speed
- Fixed dates in FITS cubes
