 #### Backwards incompatible changes
 
+#### Removal of `GEOLOCATION` constant from `ol/has`
+
+If you were previously using this constant, you can check if `'geolocation'` is define in `navigator` instead.
+
+```js
+if ('geolocation' in navigator) {
+  // ...
+}
+```
+
+#### Removal of CSS print rules
+
+The CSS media print rules were removed from the `ol.css` file. To get the previous behavior, use the following CSS:
+
+```css
+@media print {
+  .ol-control {
+    display: none;
+  }
+}
+```
+
+#### Removal of optional this arguments
+
+The optional this (i.e. opt_this) arguments were removed from the following methods.
+Please use closures, the es6 arrow function or the bind method to achieve this effect (Bind is explained here:
+https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).

+Previously, maps showed multiple worlds at low zoom levels. In addition, it used to be possible to pan off the north or south edge of the world.  Now, the view is restricted to show only one world, and you cannot pan off the edge. To get the previous behavior, configure the `ol/View` with `multiWorld: true`.

 If you were previously using `Vector` layers with `renderMode: 'image'`, you have to remove this configuration option. Instead, use the new `ol/layer/VectorImage` layer with your `ol/source/Vector`.
 
+##### New declutter behavior
+
+If a map has more than one layer with `declutter` set to true, decluttering now considers all `Vector` and `VectorTile` layers, instead of decluttering each layer separately. Only `VectorImage` layers continue to be decluttered separately. The higher the z-index of a layer, the higher the priority of its decluttered items.
+
+Within a layer, the declutter order has changed. Previously, styles with a lower `zIndex` were prioritized over those with a higher `zIndex`. Now the opposite order is used.
+
+On vector layers, even if decluttered images or texts have a lower z-Index than polygons or lines, they will now be rendered on top of the polygons or lines. For vector tile layers, this was the case already in previous releases.
+
 ##### New `prerender` and `postrender` layer events replace old `precompose`, `render` and `postcompose` events
 
 If you were previously registering for `precompose` and `postcompose` events, you should now register for `prerender` and `postrender` events on layers.  Instead of the previous `render` event, you should now listen for `postrender`. Layers are no longer composed to a single Canvas element.  Instead, they are added to the map viewport as individual elements.
