 # Observe.js - Change Log:
 
+## Version 0.8.1:
+- The "unload" window event has been replaced with "pagehide" (due to "unload" being deprecated).
+- The public function "setConfiguration()" will now only update the configuration if something in the configuration has been changed.
+- All public functions now only accept the right variable types for data (to prevent issues from occurring).
+- Added "use strict" support internally and updated all public functions to use the new scope.
+
+<br>
+

 ## Version 0.8.0:
