 ## [Unreleased]
 
+### Changed
+
+- The BlueprintImplementableEvent have been changed to BlueprintNativeEvent in order to allow them to be implemented from the child C++ classes as well. This won't break any existing Blueprint code that relies on the previous BlueprintImplementableEvent signature.
+
 ### Fixed
 
 - Add a missing release note entry for the v1.8.0 release to the changelog file.
