Return of Them is in beta. You have to opt-in before you can try any of the new features.

To opt-in, right click DST in Steam, select the 'betas' tab and select 'returnofthembeta', after that wait for the game to update and you're in.

Keep in mind your current worlds are separate from the beta worlds and will not carry over into the beta to keep them safe. And worlds you create in the beta will be wiped after the beta is over.
