+
+
+## 1.9.0
+### New features
+- On Gridless scenes, tokens can now snap to their speed limits, to make full usage of a token's movement speed easier. This feature can be temporarily disabled by pressing Shift during drag and can be disabled completely in the settings.
+
+### Bugfixes
+- Non-square tokens (e.g. 2x1) now work correctly on square grids

+
+
+## 1.5.3
+### 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))
+- The Generic Speed Provider now has good default settings for the Dungeon Crawl Classics (dcc) game system.
+
+
+## 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))
+- Grid highlighting now also works for tokens that don't have an actor.
+
+
+## 1.5.1
+### Bugfixes
+- The hint that tells users how to enable difficult terrain measurement in Drag Ruler is no longer shown if no terrain layer module is installed.
+
+
+## 1.5.0
+### New features

+### Bugfixes
+- Fixed a bug where a token would move to the incorrect location if it is was dragged and released very quickly ([#51](https://github.com/manuelVo/foundryvtt-drag-ruler/issues/51)) - thanks to Silver Raven for helping me track down this bug!
+
+
+## 1.4.5

 # Drag Ruler
-This module shows a ruler when you drag a token to infrom you how far you've dragged the token from it's start point. Additionally, if you're using a grid, the spaces the token will travel though will be colored depending on your tokens speed. If you're using a gridless map the ruler color will change to convey this information.
+This module shows a ruler when you drag a token or measurement template to inform you how far you've dragged it from its start point. Additionally, if you're using a grid, the spaces the token will travel though will be colored depending on your tokens speed. By default, three colors are being used: green for spaces that your token can reach by walking normally are colored green, spaces that can only be reached by dashing will be colored yellow and spaces that cannot be reached with the token's speed will be colored red. If you're using a gridless map the ruler color will change to convey this information.

-## Path color
+## Supports Tokens of all sizes
-![Drag Ruler demonstration](https://raw.githubusercontent.com/manuelVo/foundryvtt-drag-ruler/5177746fbb4edb28b6ba09137247d142af575c47/media/drag_ruler.webp)
+Terrain ruler has excellent support for tokens of all sizes. The Ruler will always originate from the token's center and will always highlight all the squares that tokens move over.
 
-The token has a speed of 30ft. All squares on the path within that range are colored in the players color. If the token is running it can cover double that range (this can be changed in the settings). All Squares on the path that can only be reached while running are colored in yellow. Squares on the path that the token cannot possibly reached at regular speeds are colored red. This coloring behavior can be tweaked in the settings and can be overridden by modules and game systems to provide more granular, game system specific control. For more information on how to do this see the [API](#api) section of this document.

-## Waypoints
+## Difficult Terrain support
-You can add waypoints to the path by pressing spacebar while you drag the token. To remove a placed waypoint press the right mouse button.
+**To use support for difficult terrain you must install the [Terrain Ruler](https://foundryvtt.com/packages/terrain-ruler) module**
 
-![Demonstration of Waypoints](https://raw.githubusercontent.com/manuelVo/foundryvtt-drag-ruler/5177746fbb4edb28b6ba09137247d142af575c47/media/waypoints.webp)
+With the Terrain Ruler module installed, Drag Ruler is able to take difficult terrain that was placed down using the [Enhanced Terrain Layer](https://foundryvtt.com/packages/enhanced-terrain-layer) or [TerrainLayer](https://foundryvtt.com/packages/TerrainLayer) module into account.

-## Why would I want to use this instead of ShowDragDistance?
+## Movement history (optional)
-ShowDragDistance isn't maintained anymore. This means that it is at risk to stop working with every foundry update. In fact this process has already begun. As of Foundry Version 0.7.9 ShowDragDistance doesn't work anymore on gridless maps. Drag Ruler on the other hand is fully compatible with the current Foundry release and I'll continue updating it for future foundry releases for the forseeable future.
+*This feature can be disabled in the settings if you don't like it*
 
-In addition Drag Ruler provides more flexibility for game systems and modules via it's api to provide an experience that fits the rules of the game system that you are playing best.
+During combat, Drag Ruler will remember the path a token has taken during it's turn. When the token is being picked up again, Drag Ruler will continue measuring where it has left off. The path of the previous movement will be dipslayed in a faded color.
+
+![Demonstration of the Movement History](https://raw.githubusercontent.com/manuelVo/foundryvtt-drag-ruler/709774b25f7dd818a90591165f74b3e6dbc788cc/media/movement_history.webp)
+
+
+## Pathfinding
+**To use pathfinding you must install the [routinglib](https://foundryvtt.com/packages/routinglib) module**
+
+When routinglib is installed, Drag Ruler can automatically place waypoints to walk around walls and terrain to reach the destination with the shortest possible movement. Pathfinding can be activated using a configurable key. Alternatively, Drag Ruler can be configured to always use pathfinding when a token is being dragged.
+
+Pathfinding is restricted to GM users by default, since the pathfinding algorithm can create ways that lead through unexplored fog of war. If you want to allow your players to use Drag Ruler's pathfinding functionality, you need to enable the associated setting in Drag Ruler's module settings.

 ## Game systems with Drag Ruler integration
-Drag Ruler will work with all Foundry VTT game systems. However some game systems offer a special integration via the [Drag Ruler API](#api), that allows Drag Ruler to take the rules of the game system into account when dispaying speeds (such as weight carried or conditions that apply to the character), offering a smoother experience. While some game systems offer this integration natively, for other game systems there are modules providing the integration. If the integration is provided via a module you need to install and activate both Drag Ruler and the integration module to benefit from the integration.
