 incremented a variable and not a pointer. This resulted in a bug in a
 surface counting iterator.
 
+### Issue 25
+
+  * github issue number: N/A
+  * Fixed: 1.6.0
+
+Cagebreak, beginning with release 1.5.0, when a keybinding containing an output
+configuration is removed from the list of active keybindings, the output
+configuration contained in this keybinding is destroyed in order to
+prevent memory leaks. However, after an output configuration was applied,
+it was inserted into the list of active output configurations and if it
+was later destroyed, this led to a use-after-free memory corruption.
+Starting from release 1.6.0, output configurations are copied before
+being inserted into the list of active output configurations and
+therefore remain valid even if the original is freed.
