With this release, we move away from our subversion code repository and mantisbt bug tracking to use gitlab.com instead. The old services will still be online for a while, but will not be updated. Please use the new services to report bugs and get the code.

Remember that Siril is developed without Windows and that we rely on Windows users to test and give us feedback about integration or porting problems.
