## Version 4.0.0
The MiniGUI development team announces the availability of MiniGUI 4.0.0.
However, currently, it is still in the beta/pre-release stage. We plan to
release the first stable version about Jun. 2019.
We now encourage the MiniGUI users to use this version for any new MiniGUI
We strongly recommend that you use this version for any new MiniGUI
apps, especially if the new features of MiniGUI 4.0.0 are must for your
new apps.

* We tuned and optimized MiniGUI's logical and device font interfaces to
support the new features above.
Another important features of this version are two engines dedicated to Linux
kernel:
* 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,
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'.
Another important features of this version are the new following engines:
* The NEWGAL engine of `drm` to support modern DRM-driven graphics cards. By using
`drm` engine, one MiniGUI app can now use the hardware-accelerated graphics
rendering for 2D/3D graphics.
* The IAL engine of `libinput` to support all modern input devices including
mouse, keyboard, joystick, switch, multiple touch panel, gesture, tablet tool,
and table pad. In MiniGUI 4.0, we introduce `MSG_EXIN_XXX` messages to support

chunk allocation.

MiniGUI mainly uses this library to support the dumb frame buffer
(no hardware acceleration).
In order to support the hardware acceleration, you need to write some
code for your graphics card or GPU as a sub driver of `drm` engine
outside MiniGUI.
To avoid modifying the MiniGUI source code when supporting new GPUs,
the `drm` engine has adopted a scalable design.
* You can directly use the `drm` engine to run MiniGUI on a GPU
which supports dumb frame buffer.
