A Stabilization Version

Once again, this version is a stabilization release of the 1.2 series. Therefore, there are no new features, but Siril becomes more stable thanks to all the community feedback. This is why it is very important to report any bugs you find, as it is generally the only way to have them fixed in the next version.

We thank you for your continued support and valuable feedback. Download Siril 1.2.2 now and enjoy a more stable and reliable version!

What’s New with Siril 1.4?

The upcoming version 1.4 is making great strides. We are still in the process of introducing new features but should be approaching a stabilization phase quite soon. It represents a major advancement, almost a break with previous versions: a lot of care has been put into ergonomics. Also, the number of new features is becoming very significant and we can’t wait to release a beta version. Stay tuned, you never know!

Contribute to Siril

Of course, Siril is a computer program developed by fallible humans, and bugs may still exist. If you think you’ve discovered one, please contact or write a bug report if it isn’t already present in the list of known bugs . A documentation page has been written to help you report a problem.


Developing software is fun, but it also takes up nearly all of our spare time. If you like Siril and would like to support us in continuing development you’re welcome to donate a small amount of your choice.
