Siril 1.2.6 Release Notes

We are happy to announce the release of Siril 1.2.6. Although Siril 1.2.5 was supposed to be the last update in the 1.2 series, a critical bug in the Windows version required us to release a new patch. This bug was introduced after a recent update of cfitsio which caused issues with widechar filenames that were not UTF-8 encoded.

This update mainly addresses this problem, ensuring that Siril works seamlessly with non-UTF-8 filenames on Windows. We appreciate your patience and feedback in helping us resolve this issue.

List of fixed bugs (since 1.2.5):

  • Fixed issue with widechar filenames on Windows after cfitsio update.
  • Fixed sign error in Messier catalog
  • Fixed Save As feature
  • Changed configuration directory on macOS to org.siril.Siril

Downloads

Siril 1.2.6 is available for download on the most common platforms (Windows, macOS, GNU/Linux). You can download it from the download page.
