On the Issues board, you can drag a card by any part of it into another status column. Previously only a small Drag button inside the card started a drag, and in some browsers it did not work.
Each card shows its priority, assignee, identifier and project. Move to on the card lists the statuses, for moving an issue without dragging.
The descriptions of Kanban Boards and Issues now say when to use each: Kanban Boards for any kind of work with columns you name, and Issues for bugs and product work.
