+## 0.6.7 (2026-09-30)

+- `leaves_after: { minutes: 10 }` on a state: a record that has been there that long leaves its bucket's lists (days, hours and minutes add up; swept every minute; the event log keeps it). Trainer: `leaves_after` per stage on a need. A Klingenberg Bygg card taken off the front page leaves the office's list ten minutes later instead of standing there greyed out.
+
+## 0.6.6 (2026-09-30)
 
 - `one_per_person: true` on an alternative: each signed-in person keeps one record there, their own. The form opens filled in with it, a file left unchosen keeps the one already there (shown beside the picker), and sending again replaces the card instead of adding one. Two sends at once settle on the newest. Trainer: `one_per_person` on a need entered from inside; Klingenberg Bygg's people each edit their own card on the front page.
 - Send is disabled from the moment it is pressed. Files upload before the form is sent, and a second press in that time used to send it twice.
