 <!-- add unreleased items here -->
 
+* Added
+  * Explicitly export own first-level submodules via package manifest (via [#1066])  
+    When used with bundlers/packers downstream, this might enable better tree shaking due to scoped imports.
+* Refactor
+  * Ease internal tree shaking (via [#1066])
