 ### Features
 
-### Bug Fixes and Improvements
+- Make drop target depth in last-of-subtree locations dependent on x-coordinates of the mouse, allowing the user to
+  drop in higher depths than the currently hovering item. This behavior is automatically used if `renderDepthOffset`
+  on the renderers is set to a non-zero value. (#148)
+- Add `setDomFocus` argument to focus-item methods to provide an escape hatch to set the focus state of an item in RCT
+  without updating the DOM focus. This defaults to true in all existing methods to maintain the current behavior if
+  it is absent. (#336)
+- Allow customizing when a subtree is rendered or not with the new `shouldRenderChildren` prop. This can be used to 
+  create opening and closing animations on subtrees. See [Demo](https://rct.lukasbach.com/storybook/?path=/story/core-basic-examples--animated-expanding-and-collapsing)
+  and [Demo Implementation](https://github.com/lukasbach/react-complex-tree/blob/main/packages/core/src/stories/BasicExamples.stories.tsx#L561) for details. (#333)

--->
+- Fix a bug where the `parentId` property in the `renderItemsContainer` render method was incorrectly set to the tree id
+  for the root container.
