How can it be? There are no recent changes or, better yet, everything is new, since this is the first version. Everything is new, text, design, functionality. The improved version (which will follow) will test the update procedure.
Do not install, this is just a test.
I wanted to see how much time does it take for me to publish an application. That's all, no need to install, it will just display a text which you can also see in the screenshots.
