The roadmap for Siril is being updated for its after-release life. The main coming developments are completely remaking the conversion and sequence features to handle any list of files, and providing a registration that takes image rotation into account. Ideas are stored in the TODO file, and the list of known bugs is maintained in the BUGS file. The complete changelog is available in the SVN log (not available online), a summary is available in the news section here and in the page of each release, as well as in the ChangeLog file. If you want to contribute, you are welcome!
