== Trivia ==

* This is currently the only system in the game to have/be between two beta systems.
* In both versions of the game, it is possible to unlock this system after unlocking [[Progressbar 1]].
* In version 0.33, this system was called "Progressbar XPi" and was unobtainable.
** It was probably planned for this system to be named "Progressbar XP", as seen in version 0.28 in the upgrade window, but was renamed in version 0.30.
** The reason why it was unobtainable may be because there was another system in the source code called [[Progressbar Wista]] which used the "XPI" folder.
** This is first system in the game (by release) that was once unobtainable. The second one was [[Progressbar 11.22]] and the third was [[BarOS 10.III]]
* Prior to version 0.5420, the font in Progressbar XB to [[Progressbar 7]] used the same font used in [[Progressbar 95]] to [[Progressbar Whisper]].
