+## Unreleased

+- What a person wrote on a card (a bio) is shown as markdown: paragraphs, line breaks as typed, lists, emphasis, and links to https, mailto or tel marked `rel="nofollow ugc"`. No images and no raw HTML, which is stricter than the site's own descriptions. The desk still shows the text as written.
+
+## 0.6.8 (2026-09-30)
+
+- An upload that did not arrive says why: larger than 20 MB (checked in the browser before anything is sent), a site that takes no files (no Garage configured), not allowed from here, or anything else. It used to say "try again, or with a smaller file" whatever the reason, which sent people looking for a smaller file when the site had no storage at all.
+
 ## 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.
