There are a few people who want Cinelerra GG included in Solus' repository. But core team don't agree to do so, because you don't keep old tarballs. It might cause some problems when a rebuild is needed and maintainer wasn't able to update the package right when a new version was released, or a regression occurred. Could you please keep one previous tarball?

Then it could be added to Solus repos, and this would enable a lot of new users to use this great software.
