-### Breaking changes
-
-* The `olcs.OLCesium` constructor signature has changed. Use
-  `new olcs.OLCesium({map: map, target: target});` instead of `new olcs.OLCesium(map, target);`
+* Breaking changes
+  * The `olFeatureId` has been removed from the picked Cesium counterpart.
+    Use directly `olFeature` as illustrated in the synthetic vector examples.
+  * The `olcs.OLCesium` constructor signature has changed. Use
+    `new olcs.OLCesium({map: map, target: target});` instead of `new olcs.OLCesium(map, target);`
+* Custom synchronizer function may be passed to the OLCesium constructor
+* Core functions for implementing custom 2D-3D transitions à la Google Map
+* Store the `ol.Feature` in the Cesium counterpart instead of an id.
+  Use `primitive.olFeature` to read it after picking. See the synthetic vector examples.
+* Allow 3D warmup while displaying the 2D map
