- Outbounds — removing a deleted member from a
selector/urltest: if an outbound was deleted without first removing it from the selector/urltest that referenced it, the stale reference became impossible to remove in the UI (a 1.5.x regression vs 1.4.x). It lingered in the saved config and could make sing-box fail to restart. Such stale members are now rendered as removable (struck-through) chips so they can be cleared. (#14)
