+[NOTE]
+In {productname} 7.0, the default setting for `highlight_on_focus` was changed from `false` to `true`. Any editors using this `highlight_on_focus: true` option in {productname} , can remove this option from their {productname} init configuration when upgrading to {productname} 7.0.
+
 The `+highlight_on_focus+` option adds a blue outline to an instantiated {productname} editor when that editor is made the input focus. When using the `oxide-dark` skin, the outline is white.
 
 This allows users to clearly see when the editor is in focus, or which editor has focus if more than one {productname} instance is available.
