MarsSeed [1] filed a deletion request for darktable-rc [2]: I think this package can be deleted. The project hasn't released any RC (release candidate) versions in close to 3 years. There have only been stable point releases and a major stable release (v3 -> v4). And also there are nightly builds. Arch repo carries a 2.5 years newer stable version than this RC package.
