+- Feature: Add new reusable component `RadioCard.vue` to the package.
 
+## 2.0.1
 - Fix: Add `crossOrigin` differently to layer sources that are an instance of `ImageWMS` as they require it being set as `crossOrigin_` to be recognized.
 - Fix: Add missing `font-family` css so that tooltips are always `Arial, sans-serif`.

 # CHANGELOG
 
+## unpublished
+
+- Feature: Add new configuration parameter `measureOptions` to allow users to select a measurement mode when drawing a feature. This way, a length / area in the selected unit is added to the drawn feature.
+- Fix: Update initial value of `drawMode` to a selectable value if the default `Point` is not a drawable option.
+- Fix: Adjust type `DrawGetters` regarding its keys `selectableDrawModes` and `selectableModes` to correctly reflect that they represent objects.
+- Chore: Add `@polar/core` as a dependency as the component `RadioCard.vue` has been moved from this package to `@polar/core`.
+
 ## 2.0.0
 
 - Breaking: Upgrade peerDependency `ol` from `^7.1.0` to `^9.2.4`.
