Siril 0.9.7

Release date: September 21st, 2017.

This release is the seventh stability release for the 0.9 branch. Its SVN revision is 1822, but it also has an SVN tag: 0.9.7. Stability updates and minor improvements occur in the dedicated 0.9 branch. Also, Siril is now AVAILABLE FOR WINDOWS !!! But keep in mind that we do not use Windows ourselves: this application was generously packaged by Partha Bagchi (see his website). Some bugs may occur and for this reason, Windows release will always be in beta version. Partha is also the maintainer of the OS X package.

  • Debian testing: 64 bits
  • Ubuntu / Linux Mint:
 sudo add-apt-repository ppa:lock042/siril

  • Fedora, Mageia 6: All

  • AppImage: If you don't find a package for your distribution, you can try to download the AppImage binary. It has been tested on many systems and could work on yours. Make the file executable, and run it. That's all.
