 ### Next release

+#### `ol.animate` now takes the shortest arc for rotation animation
+
+Usually rotation animations should animate along the shortest arc. There are rare occasions where a spinning animation effect is desired. So if you previously had something like
+```js
+map.getView().animate({
+  rotation: 2 * Math.PI,
+  duration: 2000
+});
+```
+we recommend to split the animation into two parts and use different easing functions. The code below results in the same effect as the snippet above did with previous versions:
+```js
+map.getView().animate({
+  rotation: Math.PI,
+  easing: ol.easing.easeIn
+}, {
+  rotation: 2 * Math.PI,
+  easing: ol.easing.easeOut
+});
+```
+
 ### v4.2.0

 #### Return values of two `ol.style.RegularShape` getters have changed
