Sorry for the slow reply, but if you bought the Physical PC edition from Limited Run you should have received an itch.io key on April 19 which you can use to update to the latest version.
If you bought a PS4 or Switch physical edition, the game will update when we launch 1.4 on consoles (we're still working on it).

Hi, I have bought the Physical PC edition from Fangamer back in December 2019. I have checked my email and there was no update key. Will the Fangamer buyers be able to update soon or is it maybe possible to directly contact you and manually verify the purchase and get the update key? I already own the latest version of the game on Steam and Epic Games, but I would love to update the physical copy, too. Thanks!
No problem! I bought the Physical PC edition from Fangamer, but it wasn't during the Limited Run release. I never received an itch.io key. The Physical PC edition is the only version I have on PC, so I don't currently have a way to get 1.4. Is there any way to get the update for this version? Thanks again.
