 * Fix `httpPorts` host detection so accounts/cast/family/albums subdomains serve their static frontends again
 
+## 0.5.2 (2025-11-05)
+
+* Allow httpPort hostnames like `cast.ente`/`accounts.ente` so Cloudron can append the primary domain (`.due.ren`) automatically
+
 ## 0.5.0 (2025-11-04)
 
 * Proxy Museum GET/HEAD routes (e.g. `/collections`, `/files`, `/remote-store`) so clients that talk to the primary host without `/api` still hit the backend
