+## 1.7.0
+**BREAKING** This update is incompatible with previous Terrain Ruler versions. If you're using Terrain Ruler, make sure you update Terrain Ruler to at least version 1.3.0.
+
+### New features
+- A ruler will now be shown when dragging measurement templates over the map ([#13](https://github.com/manuelVo/foundryvtt-drag-ruler/issues/13))
+- Drag Ruler can now measure difficult terrain on gridless maps (if the Terrain Ruler module is installed and enabled)
+- Improved the positioning of the labels around the ruler. The labels should now never overlap with the waypoint.
+
+### Bugfixes
+- Fixed a bug that sometimes measured diagonals incorrectly with the 5/10/5 grid rule
+- Fixed a bug that would cause the ruler to re-measure when the shift key is being pressed or released while a token is moving
+
+### Compatibility
+- Drag Ruler's Generic Speed Provider is now aware of good default values for the Starfinder game system
+
+### Translation
+- Corrected typos in the german translation (thanks to CarnVanBeck!)
+
+### API
+- The old API that Drag Ruler offered prior to version 1.3.0 is now deprecated. Speed Providers that still use this API will continue to work for now, but will generate a warning in the console about the deprecation. All modules and game systems offered on the FoundryVTT website have already updated to the new API. If you see the deprecation warning, please consider updating to the current version of the respective system/module you're using.
+
+
+## 1.6.5
+### Bugfixes
+- Drag Ruler no longer gets stuck if the user presses ESC during drag ([#70](https://github.com/manuelVo/foundryvtt-drag-ruler/issues/70))
+
+
+## 1.6.4
+### Bugfixes
+- Fixed a bug where a bug in a Speed Provider could lead to the ruler getting stuck, leaving the token immovable
+
+
+## 1.6.3
+### Bugfixes
+- If the movement history for a token is being updated (for example by a history reset by the gm) while a player is currently measuring a distance for that token the history change is now being reflected in the active measurement.
+
+### Compatibility
+- Drag Ruler's Generic SpeedProvider is now aware of good default values for the Savage Worlds Adventure Edition game system
+
+
 ## 1.6.2
 ### Bugfixes
 - The reset movement history button now resets the movement history for all players, not just for the GM
