- TODO: Enumerate changes.
+This minor release adds two new functionalities that support our new Dragons app.
 
+## New features
+
+It's now possible to call `CBCCreatePresentableNavigationTree` to create a navigation tree that only consists of examples that implement the `catalogIsPresentable` method and return `YES` to it.
+`CBCNode` now has a new property called `debugLeaf` which is also a `CBCNode`. If an example implements the `catalogIsDebug` method and returns `YES`, then that example will become the
+`debugLeaf`. When the `debugLeaf` is set, then in the Dragons app it will become the initial view controller in the navigation. NOTE: If there are multiple examples that return `YES` to
+`catalogIsDebug` then the last class that is parsed while going through the hierarchy is the one to be set as the `debugLeaf`.
