* '''EV_ACTION_SEQUENCE''' - Now event_data is defined with named tuples for easier reading of the action sequence parameters.

** Added 'file_drop_actions' for OS based file drag and drop from exterior applications to a Vision2 application.
** Added 'file_drop_actions' for OS based file drag and drop from exterior applications to a EiffelVision 2 application.
** Made 'idle_actions' obsolete as it is not thread-safe
** Now a full garbage collection occurs if the application has been idle for 30 seconds

* '''STRING_GENERAL''' - All string operations now take STRING_GENERAL instead of STRING, this allows for mixing and matching of 8 and 32-bit string objects and allows for 32bit Unicode values, the return value is always STRING_32
* '''EV_APPLICATION'''
** Added action sequences for querying global user events such as pointer clicks and motion
** Vision2 is now thread-aware with the addition of thread-safe 'add_idle_action' and 'do_once_on_idle' that allow threads to add agents to update the main GUI thread in a safe manner

* '''EV_GRID_ROW''' - Added `insert_subrows' for the quick addition of multiple subrows at once.
* '''EV_WINDOW''' - Added `is_border_enabled', `enable_border' and `disable_border'. This lets you turn on/off the border as required.
* '''EV_HEADER_ITEM''' - Added `user_can_resize' which enables you to prevent a user from resizing the item. Also added `minimum_width' and `maximum_width' which permit you to restrict the resizing of the item within a particular range.
* '''EV_MESSAGE_DIALOG''' - All message dialogs now use their associated message icon as the icon pixmap displayed in the title bar, instead of the standard EiffelVision2 icon.
* '''EV_MESSAGE_DIALOG''' - All message dialogs now use their associated message icon as the icon pixmap displayed in the title bar, instead of the standard EiffelVision 2 icon.
* '''EV_DYNAMIC_TREE_ITEM''' - The `subtree_function' is now only executed when you expand the item. In the previous version, querying the contents of the item caused the subtree function to be executed, filling the children.
* '''EV_COMBO_BOX''' - Added `is_list_shown', `list_hidden_actions' and renamed `drop_down_actions' to `list_shown_actions'.
* '''EV_APPLICATION''' - Added `pointer_motion_actions', `pointer_button_press_actions', `pointer_button_release_actions', `pointer_double_press_actions', `mouse_wheel_actions', `key_press_actions', `key_press_string_actions' and `key_release_actions'.

'''Breaking changes'''
* '''EV_TREE_NODE_CONTAINER''' - This class is no longer used in EiffelVision2, and if you were relying on it, you should use EV_TREE_NODE_LIST instead. The type of `parent' for tree nodes has been changed from EV_TREE_NODE_CONTAINER to EV_TREE_NODE_LIST, so if you retrieve the `parent' and then attempt to iterate, you may have declared an instance of EV_TREE_NODE_CONTAINER. In this situation, you should simply change the definition to EV_TREE_NODE_LIST instead.
