Project Zomboid Updated like Crazy. Need information/help .

So Project Zomboid has been updating like crazy. I left it for a bit back when it was before these 0.2 updates and there is so much to the game now. Unfortunately when i go to the wiki i can't get information on anything new really... I mean apparently there is experience for stuff like strength? How do i know if i am improving it? What is this new item called matches? Does it work on the same premises as a lighter? I can cut down trees now? And can i actually drop items now on the ground?

Is there some place where i can get information on all the new stuff without searching through each update list? Can we just share what we know here?
