Since 1.6.0 "Show" both whitelisted a method for its group and hid it from everybody else. A group shown ordinary methods next to a free one therefore took the ordinary ones away from every stranger, who was left with only the free method. "Only" now carries the reservation; "Show" is just the group's whitelist. Existing show rules are converted to only once on update so the checkout does not change until the shop chooses.
