Oswald X

Oswald X is a never released version of Oswald by Oswald Software Team.
The team finally made 10 major versions of Oswald operating system. And so, they planned to create more X versions and their codenames, releasing an X version every 2 years, just like Sviger did. However, the team didn't realize that they made over 17 versions of Oswald X.
