The feature table predated twenty-one parity rows. It described releases as read-only, and omitted labels, list filtering, search, drafts, retargeting, stacks, compare, notifications, forking, bookmarking, watching, dependency checks, organisation management, profile editing and the markup picker.
It now also says what is deliberately absent and why: minting an API token and deleting or transferring a repository stay SSH-only, because each wants a typed confirmation or carries a credential.
