+* Fix missing `home` option for DERP service **1**
+* Fixes and improvements

+**1**:
+
+You can now choose what the DERP home page shows, just like with derper's `-home` flag.
+
+See [DERP](/configuration/service/derp/#home).

+### 1.11.13
 
 * Fixes and improvements
 
+_We are temporarily unable to update sing-box apps on the App Store because the reviewer mistakenly found that we
+violated the rules (TestFlight users are not affected)._
