Siril 1.0.1

Release date: April 6, 2022

This is the first minor update of the 1.0 branch. It fixes some of the problems identified in the 1.0.0 version, as listed in its page. The only feature to see some improvements as well is Pixel Math, as explained in the ChangeLog file.

The commands reference page for this version is the same as for 1.0.0: see the list of commands for siril-1.0.


See the page of the main site for a detailed presentation of the version and download links.

  • Fixed crash when changing image with preview opened
  • Fixed crash when pressing Stop button during script execution

Known issues

Inevitably, some problems exist in every release, even if we do our best to verify that everything works as expected. For convenience, here is a list of problems that were identified after the release, potentially corrected in subsequent minor versions:

  • the installer for Mac was the wrong version, it has been replaced in the same file on the 7th of April at 8am UTC
  • the installer for windows seems to be missing some icons because of a change in the icons of GTK+ just before we packaged it, but it's just a cosmetic problem
  • the seqcosme command, for cosmetic correction applied to a sequence from a file of bad pixels, was not correcting bad columns to all images in the sequence - fixed for next 1.0
  • starting scripts from the command line of the GUI with @ (as explained here) only works one time - filed as #796
  • conversion had a limit in the length of the output path (a total of 127 characters), this is fixed for next 1.0 (no more limit)
  • a program crash could happen during star detection when a star was on the image border - fixed for next 1.0
  • 8-bit FITS images are not processed or loaded correctly - filed as #812
  • plots would crash with negative values in X axis - fixed for next 1.0
  • the min/max display doesn't set the low cursor to the image minimum, it's always 0 - fixed for next 1.0
  • doing undo/redo multiple times could fill the used memory with 32-bit images - fixed for next 1.0
  • opening another image when a preview from a tool on current image is opened leads to possible bad display of the new image - fixed in 1.2 only
