 ## New Features
 
+### (2024-04-23) Custom AnimationSet actions:
+
+- Introduces support for defining custom actions in the animations set and invoking them using the setCustomAnimation function.
+
+#### Usage Example:
+
+```js
+import { useGame } from "ecctrl";
+
+const animationSet = {
+  idle: "Idle",
+  walk: "Walk",
+  run: "Run",
+  .....
+  // Custom action
+  custom: {
+    fly: "Fly"
+  }
+};
+
+// ...
+const setCustomAnimation = useGame((state) => state.setCustomAnimation);
+// ...
+setCustomAnimation("fly");
+```
+
+#### Note:
+
+Ensure to update your `animationSet` accordingly to include any custom animations you wish to use in your game.
