“New” player. What do I need to know?

I started playing DayZ Standalone when it first dropped in Alpha in 2013 and played through to launch in 2018 but soon after dropped it because it felt stale after a while (especially since none of my friends played it).

But I’ve met some friends from work that play it often and they invited me to join them tonight. Going 8 years without playing is leaving me wondering: what’s new? What’s different? What should I look out for? And in general: what do you think I need to know as a returning player?
