+## 2026-09-10 — Marking a subscription read
+
+An OPML subscription's page now has **Mark all read**, sitting where every other feed keeps it --
+before Unsubscribe. The fix is in the handler rather than the button: `read-all` resolves the feeds
+whose group is the given id (through `subscriptions()`, so a child promoted to config counts too)
+and marks those, since the subscription's own row holds no entries and marking it did nothing.
+
+---

 ## 2026-09-10 — A folder counts what it holds
 
 An OPML subscription has no entries of its own, so its row always read `0 unread` no matter how much
