 The following interfaces are not yet implemented:
 
-- Every interface introduced after VST 3.0.0
+- Every interface introduced after VST 3.0.0 with the exceptons of
+  `IEditController2` and `INoteExpressionController` which has already been
+  implemented
 - The [Presonus extensions](https://presonussoftware.com/en_US/developer),
   although most of these things seem to overlap with newer VST3 interfaces
