@@ -1,7 +1,3 @@
-## 0.1.0
-* This release updates getApplicationSupportPath to use the application ID instead of the executable name.
-  * No migration is provided, so any older apps that were using this path will now have a different directory.
-
 ## 0.0.1+2
 * This release updates the example to depend on the endorsed plugin rather than relative path
