[ANN] Kivy 1.3.0 released

[Mathieu Virbel]

Hi everyone,

We are pleased to announce Kivy 1.3.0.

Kivy is a full featured framework for creating novel and performant
user interfaces, such as multitouch applications, under the LGPL 3
license. The framework work on Windows, OSX, Linux, Android and iOS.
All downloads are available on the website:

http://kivy.org

What's new in this release ?

- New Kivy UI theme: we changed the previous theme in favor of a new
one, inspired by Android theme. Button, Slider, ProgressBar,
Switch got a fresh styling, making the default Kivy application
more readable!

- New Tabbed Panel widget: new experimental widget that provides a
way to manage different widgets in each tab.

- Interactive Launcher: you can now experiment to build Kivy UI in
live, within IPython or any others Python interpreter. It provides
an user-friendly python shell interface to an App, so that it can
be prototyped and debugged interactively.

As usual, any issues / features should be reported at:
