Drop additions that the UX plan does not ask for: - the interactive label edit form; label edit now requires a flag - label clone and the skip mode of label creation it needed - repo rename rewriting the Git remote or tea.repository; it now warns that the remote still points to the old name - the extra "source" remote on clones of pull mirrors - run artifact download, which duplicates run download --zip - 256-color and 24-bit label swatches; colors stay ANSI 16 - config list --show-source (config get keeps it) - the membership and access GETs before team member/repo add and remove; Gitea's PUT and DELETE are idempotent label edit/delete keep --by-name: it is the only way to address a label whose name is a number that is also another label's ID.
