Captcha support, which is in 0.17 but was dropped from 0.18. It’ll be added back to 0.181, which is what lemmy.world admins are waiting for.
I believe it was dropped because the 0.18 release removed websockets, since that doesn’t scale up to lots of users very well. The developers priority was understandably getting lemmy stable despite massive user growth. Unfortunately without captchas, open sign up instances like lemmy.world will be overrun by bots.
