     4.55.1.2
         Changed getargspec call in the SDK Reference window to getfullargspec. In 3.11 getargspec is no longer supported and thus crashes
         Added try to SDK Reference event loop to catch any additional problems that may pop up in 3.11
+    4.55.1.3
+        Added Window.move_to_center - moves a window to the center of the screen. Good for when your window changes size or you want to recenter it
+        Disable debugger when installing from github
+        Better error reporting when a problem with the layout detected
