 Druid 0.3.0:
 
+- Druid:final now is important function for correct working
+
 - Add swipe basic component
 	- Swipe component handle simple swipe gestures on node. It has single callback with direction on swipe. You can adjust a several parameters of swipe in druid style.
 
 - Add input basic component
 	- Input component handle user text input. Input contains from button and text component. Button needed for selecting input field
+	- Long click on input field for clear and select input field
+	- Click outside of button to unselect input field
+	- On focus lost (game minimized) input field will be unselected
+	- You can setup max length of the text
+	- You can setup allowed characters. On add not allowed characters `on_input_wrong` will be called. By default it cause simple shake animation
 
 - Add button on_click_outside event. You can subscribe on this event in button. Was needed for Input component (click outside to deselect input field).
+- Add start_pos to button component
 
 - Changed input binding settings. Add backspace, enter, text and marked_text. Backspace now is different from android back button.
 
-- Add several examples to druid-assets
+- Changed component interest: Renamed on_change_language -> on_language_change
+- Add two new component interests: on_focus_gain and on_focus_lost
+- Add global druid events:
+	- on_window_callback: call `druid.on_window_callback(event)` for on_focus_gain/lost correct work
+	- on_language_change: call `druid.on_language_change()` for update all druid instances lang components
+	- on_layout_change: call `druid.on_layout_change()` for update all gui layouts (unsupported now)
