Jeb added all of that stuff, Notch doesn't work for Mojang anymore... This is how JEB wanted it not how NOTCH wanted it, I want it NOTCH's way, not JEB's...
Get your facts straight.
Notch added Hunger and XP in 1.8, before he stopped working on minecraft. Thus, it is Notch's way.
Also, he didn't quit, he just decided to go on "vacation" from Minecraft, so he could rest and work on other games, such as Cobalt. Notch owns Mojang, he wouldn't just quit, the interwebz would rage like the fires of hell.
