Release date: August 14, 2020

This release is a complete refactoring of Siril. It is a beta version of the upcoming 1.0 version. It comes with a new graphical user interface, support for 32 bits per channel, faster demosaicing, FITS image compression, single file FITS sequences, improved performance, and many more. See the list below for a list of new features and improvements.

See also the change log in the siril commands reference. Several new commands were added, some were modified.

Downloads

This version is a the beta version of Siril 1.0.0. In consequence, we only distribute the packages for the 3 most common platforms (Windows, MacOS, GNU/Linux). See the download page.

But as usual, since siril is a free software, it can be build on any OS from source, see the installation page.
