Beside many fixes and general improvements some new features have been added to the library:

Tabset

The tabset is a new container that implements real tabs. Until now radio buttons with the custom tab rendering had to be used to create tabbed menus. This new container provides an easy to use API to dynamically create tabbed menus that can either fill just a portion or the entire area of the display.

The API reference of the Tabset container can be found here: http://api.ugfx.org/master/group___tabset.html

Keyboard interface

A new interface has been added to the GINPUT module in order to process keyboard inputs. This new interface can be used to handle any kind of keyboard whether it be a real physical full sized QWERTY keyboard, some numpad or a virtuall on-screen keyboard.

The keyboard interface API can be found here: http://api.ugfx.org/master/group___keyboard.html

Keyboard Widget

A keyboard widget as been added to GWIN which allows to display a virtual on-screen keyboard on a touchscreen device. The keyboard allows to dynamically change the layout during runtime.

The API reference of the Keyboard widget can be found here: http://api.ugfx.org/master/group___keyboard.html

Pixmaps

A new feature called 'pixmap' has been added to the GDISP module. Pixmaps are framebuffers that can be created dynamically during runtime in RAM. These framebuffers allow to execute drawing / rendering operations directly in RAM and just blit the finished result to the display when finished. This can improve the performance of the system vastly as the main systems RAM is way faster to access and burst-writing a buffer to a display is faster than pixel-based access. Pixmaps can be created of any size during runtime. It's furthermore possible to blit the same pixmap to multiple different locations on the actual display.

Pixmaps behave like real displays and are therefore very easy to use as any GDISP drawing/rendering function call can be called on them.

The API reference for Pixmaps can be found here: http://api.ugfx.org/master/group___pixmap.html

Drivers

A few new display drivers have been added to the library: TLS8204, STMPE610, SSD1331, SSD1351

Arduino

An Arduino port has been added to the GOS module. Therefore uGFX can now run out of the box on any Arduino system.

Comments and any kind of feedback is welcomed!
