 ## Version 5
 
+### 5.1.1
+
+- Fixed a bug on requesting the state of inactive relays during the UI update:
+  - OctoRelay v5 queried the GPIO pin state of inactive relays which could cause reservation conflicts and errors
+    such as `lgpio.error: 'GPIO busy'`;
+  - The issue was found and reported by [Christoph Hagen](https://github.com/christophhagen).
+
 ### 5.1.0
 
 - Fixed compatibility issue with [Physical Button plugin](https://github.com/LuxuSam/PhysicalButton):
