 # Changelog
 
+## v0.5.1

+### Breaking
+
+* Update `EmptyDrawable` to be an immutable singleton object instead of a class. Any attempted changes to this will
+  throw an exception.
+    * Migration: `val drawable = EmptyDrawable()` to `val drawable = createEmptyDrawable()`
+      or `val drawable = EmptyDrawable`
+
+### Changes
+
+* Update `ScrollContainer` vertical scrollbar to extend the entire height of the container.
+* Update `ScrollContainer` add new `Drawable` properties that can be overridden.
+* Update `Scrollbar` add new `Drawable` properties that can be overridden.
+* Fix `Scrollbar` grabber height and position not fully reaching the correct position at the end of the scrollbar.
+
+* Adds new child tree positioning methods. NodeList updated to use just an array list to handle the indexing as the
+  multiple collections were not able to handle the movement changes.
+    * `sendChildToTop()` - sends child to top of parent tree
+    * `sendChildAtToTop()` - sends child at index to top of parent tree
+    * `sendChildToBottom()` - sends child to bottom of parent tree
+    * `sendChildAtToBottom()` - sends child at index to bottom of parent tree
+    * `addChildAt()` - adds new child to parent node at specified index
+    * `swapChildren()` - swap child positions in the parent tree
