Introduction

We are pleased to announce the release of Siril 1.4.4!

This maintenance release builds on the 1.4.x series with a series of targeted bug fixes covering sequence handling, file reading, disk space detection and script discovery. It also brings a small improvement to the script repository search.

What’s new in Siril 1.4.4

Bug fixes

  • Fixed sequence file corruption (#1204, #1934): an issue that could corrupt .seq files has been resolved
  • Fixed crash when loading a sequence with an out-of-range reference image (#1950): loading a sequence whose reference image index was no longer valid (for example after preprocessing) no longer crashes Siril
  • Fixed wrong “not enough disk space” error on macOS: external APFS/HFS volumes are now reported correctly and no longer trigger a spurious disk space error
  • Fixed script folder names on Windows: scripts placed in custom subfolders now show up under their folder name instead of being grouped under “Other”
  • Fixed regression when reading 16-bit fitseq (#1946): a regression affecting the reading of 16-bit .fitseq files has been corrected

Improvements

  • Improved script repository search: the search now also matches the category column, making it easier to find scripts by their category

Translations

Thanks to the work of a dedicated contributor, the Japanese translation of the application has improved significantly. This is a great opportunity to remind everyone that anyone can help translate Siril, and no programming knowledge is required.

If you would like to contribute in your own language, translations are handled through Weblate : simply create an account and start translating directly in your browser. Every contribution, however small, helps make Siril accessible to more people around the world.

Upgrading to 1.4.4

We recommend all users of Siril 1.4.x to upgrade to version 1.4.4. The upgrade is fully compatible with your existing Siril configuration and data.

This release is particularly beneficial if you:

  • Work with sequences and have encountered .seq file corruption
  • Load sequences with an out-of-range reference image, e.g. after preprocessing
  • Use Siril on macOS with external APFS/HFS volumes
  • Are a Windows user and want your scripts to be correctly categorised
  • Read 16-bit .fitseq files

Looking ahead

Development of Siril 1.5 continues on the master branch. For those seeking stability with the latest fixes, the 1.4 branch remains the recommended option.
