Der Dev hat die Rom leicht umbenannt und noch eine Slim-Variante neu am Start. Hier mal seine eigene Beschreibung dazu:
The two ROMs are the basis on which will begin work on optimizing and adding new features.Lollipop official came out from too little, even when I've tested thoroughly, so at the moment are very similar, using the same official google base where I removed all installed gapps choice from playstore. The xTraSlim a ROM is easy for those who want to use other kernels and suitable for less experienced users, in fact, thanks to my patch you can make the Undervolt easily enable such features currently not available to everyone. The xTraOriginal (currently xTraSmooth) is a simple, stable and good-looking rom with franco kernel, both ROMs have additions that will emerge over time, advanced power menu and so on. etc. I'll bring the system odex. I hate ROMs heavy and too personizzate, I prefer to use the official Google base having a Nexus .
The patch diffence are only the UV table...;)
