+# [1.0.0](https://github.com/fritz-c/react-sortable-tree/compare/v0.1.21...v1.0.0) (2017-08-05)
+
+
+### Bug Fixes
+
+* External node offset was shifted ([d1ae0eb](https://github.com/fritz-c/react-sortable-tree/commit/d1ae0eb))
+
+
+### Code Refactoring
+
+* get rid of `dndWrapExternalSource` api ([d103e9f](https://github.com/fritz-c/react-sortable-tree/commit/d103e9f))
+
+
+### Features
+
+* **tree-to-tree:** Enable tree-to-tree drag-and-drop ([6986a23](https://github.com/fritz-c/react-sortable-tree/commit/6986a23))
+* Display droppable placeholder element when tree is empty ([2cd371c](https://github.com/fritz-c/react-sortable-tree/commit/2cd371c))
+* Add `prevPath` and `prevTreeIndex` to the `onMoveNode` callback ([6986a23](https://github.com/fritz-c/react-sortable-tree/commit/6986a23))
+
+
+### BREAKING CHANGES
+
+* Trees that are empty now display a placeholder element
+in their place instead of being simply empty.
+* `dndWrapExternalSource` api no longer exists.
+You can achieve the same functionality and more with react-dnd
+APIs, as demonstrated in the storybook example.
