+## NEW FEATURES IN VERSION 4.0.x
+
+In this version, we enhanced and tuned the APIs related to text rendering,
+in order to support [HybridOS Foundation Class Library].
+
+* MiniGUI now provides complete APIs for Unicode characters processing.
+  These APIs conform to Unicode 12.0.
+
+* MiniGUI also provides new APIs to lay out, shape, and render glyphs
+  from complex and mixed scripts, such as Arabic, Thai, and Indic.
+
+* We tuned and optimized MiniGUI's logical and device font interfaces to
+  support the new features above.
+
+* MiniGUI now is enhanced to support input events which may be generated
+  by input devices other than standard mouse (or single-touch panel) and
+  keyboard, such as multi-touch panel (gesture), joystick, tablet tool,
+  table pad, and switch. In MiniGUI 4.0, we introduce `MSG_EXIN_XXX` messages
+  to support the input events from devices other than standard mouse
+  and keyboard. We call these messages as 'extra input messages'.
+
+* The NEWGAL engine of `dri` to support modern DRI/DRM-driven graphics cards
