 ### Releasenotes
 
+##### 0.6.0
+
+* there is a new option `-2`. It generates a `CMakeLists.txt` that includes
+a file called `CMakeSourcesAndHeaders.txt`. This is a file that you can generate
+with a second run of `mulle-xcode-to-cmake` using `sexport`.

 ##### 0.5.4
 
 * the reminder is now more readable
