Siril 1.4.1

Download SIRIL version 1.4.1 released on January 5, 2026.

Introduction

We are pleased to announce the release of Siril 1.4.1!

This maintenance release addresses several important issues reported by the community following the release of Siril 1.4.0 stable in December 2025. Version 1.4.1 focuses on improving compilation flexibility, fixing Python scripting issues, and enhancing catalogue functionality.

What’s new in Siril 1.4.1

Build system improvements

  • Fixed compilation without optional dependencies: Siril now builds correctly when compiled without libgit2, libjpeg, or libcurl (#1886, #1887, #1888, #1889)

Python scripting fixes

  • Fixed tkfilebrowser submodule: resolved issues with duplicate filenames or bookmarks (!964)
  • Improved sirilpy robustness: corrected too-strict condition and off-by-one error
  • Fixed sirilpy.FFit class: corrected data setter behavior

Catalogue improvements

  • Fixed remote catalogue: eliminated dependency on Gaia Archive for improved reliability (!969)

Upgrading to 1.4.1

We recommend all users of Siril 1.4.0 to upgrade to version 1.4.1, especially if you:

  • Compile Siril from source with a minimal set of dependencies
  • Use Python scripts that rely on tkfilebrowser or sirilpy
  • Experience issues with remote catalogue queries

The upgrade is straightforward and fully compatible with your existing Siril 1.4.0 configuration and data.

Looking ahead

Development of Siril 1.5 continues on the master branch. As mentioned in our 1.4.0 announcement, users of daily builds should exercise caution during the early phases of 1.5 development. For those seeking stability with the latest fixes, the 1.4 branch remains the recommended option.
