+### Contributors — theme credits could show an outdated name
+
+**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#1302](https://github.com/Psychotoxical/psysonic/pull/1302)**
+
+* **Settings → System → Contributors** read the theme list from a cache that is only refreshed every 12 hours, so a theme author whose name had since been corrected in the store kept showing under the old one, with no way to refresh from that screen. The list now shows the cached names instantly and quietly corrects itself from the store in the background.
