+## In development
+### Compatiblilty
+- Drag Ruler's Generic Speed Provider is now able to work with game systems that put non-number characters behind the tokens movement speed (like `30ft.`). One example for such a game system is Dungeon Crawl Classics. ([#60](https://github.com/manuelVo/foundryvtt-drag-ruler/issues/60))

+
 ## 1.5.2
 ### Bugfixes
 - Drag Ruler no longer prevents tokens that don't have an actor from being moved. ([#58](https://github.com/manuelVo/foundryvtt-drag-ruler/issues/58))
