What about blueprints?

Blueprints are officially in and they shift gameplay in a huge way. You are no longer able to craft most things off the bat. Instead, you have to find blueprints in loot barrels to learn the how to craft them. When you find say, a medical syringe blueprint in a barrel, you can either use it, or study it. If you study it (right click), the syringe disappears but you can now craft it through your crafting menu. At the moment, learned blueprints are carrying over through wipes (but not from server to server). My sense is, however, that blueprints are not intended to carry over after a wipe.

Edit: There is a new 'persistence' folder in your server identity. Deleting this will clear everyone's studied blueprints.
