+## Canvas version changes
+#### v3.1.2, v4.0.1
+Exports all existing canvas shapes, so that they can be easily unregistered from the canvas. (see README for unregistering the shapes).
+
+Also, this version introduces two new Inputs,  `strokeColorPickerEnabled: boolean` and `fillColorPickerEnabled: boolean`, also deprecates the `colorPickerEnabled` Input.
+
+For the sake of reverse-compat, the `colorPickerEnabled` input is still there and it will be used in combination with the two new variables. (ex: `colorPickerEnabled || fillColorPickerEnabled`). 
+
+#### v3.1.1 Audits the npm packages and upgrades the lodash version from 4.17.11 to 4.17.13
+
+#### v3.1.0 Merges the pull request from https://github.com/webfactorymk/ng2-canvas-whiteboard/pull/55 to allow the component to be used in Angular 8 and 9 applications. Also fixes the imports for rxjs items from 'rxjs/index' to 'rxjs'
+
+#### v3.0.4 Fixes a bug with production build and recognition of shape names by adding an abstract method in the base Shape class.
+
+#### v3.0.0 Removes the `rxjs-compat` library and adds `rxjs^6`. This means that older versions will not be supported if they upgrade to `ng2-canvas-whiteboard^3.0.0`.
+#### *This version also changes the way of how this library is built and made ready for publish.*
+
+#### For applications before Angular 6 please use versions below v3.0.0.

 # Canvas Whiteboard Shape Selector
 The `CanvasWhiteboardComponent` is now equipped with a shape selector (since the free hand drawing is now a shape because of consistency),
 The shape selector can be managed or hidden with inputs, and it basically calls the `CanvasWhiteboardShapeService` and draws all the
