 ## Changelog
 
+### v0.77.0 — per-app open_path for the "Megnyitás" link (2026-06-23)
+- The dashboard/deploy/app-info **"Megnyitás"** (open) button was hardcoded to the bare subdomain root
+  `https://{sub}.{domain}` for every app. Apps whose UI isn't at `/` (e.g. Gokapi redirects `/` away;
+  Ghost's admin is at `/ghost/`) opened to the wrong place.
+- New optional `open_path` field on `Metadata` (`internal/stacks/metadata.go`, `.felhom.yml`) appended to
+  the URL in all three link sites (`dashboard.html`, `deploy.html`, `app_info.html` via `.Meta.OpenPath`).
+  Empty = bare root (unchanged for the other 50 apps). No handler changes (all three templates already
+  carry `.Meta`). Catalog: `gokapi` → `/admin`, `ghost` → `/ghost/`.
+
 ### v0.76.0 — campaign-#3 hardening: settings recovery, restore-name validation, quiesce-marker quarantine (2026-06-22)
 
 Three controller findings from chaos campaign #3, all small, all controller-side.
