 Changes
 =======
 
+v1.3.0
+-----
+    * PyQode editor has been replaced by a custom editor due to compatibility problems with Qt5/PySide 2
+    * Settings have now been moved into FreeCAD user parameters
+    * Execute-on-save setting is now on by default
+    * Execute-script key has been changed to F9 to avoid conflicts with FreeCAD's F2, but key is still configurable
+    * New code editor automatically reloads contents of script file if changed on disk, enabling use of external editor by default
+    * Setting added to show/hide line numbers in code editor
+    * Default font size for code editor changed to 12, but size is still configurable
+
 v1.2.0
 -----
     * Made a copy of the PyQode editor which is abandoned, so that a custom version can be maintained here
