To get this update, you have to opt in inside your library:
Necesse -> Properties -> Betas -> Select 0.20.x in dropdown.
Reminder: It's recommended to back up your saves when playing on experimental version. You can do so in game on the load menu.
With this new update, I would like to invite you all to the new official Discord server, where I will be active and talk development, suggestions and bugs with players. It's also a great way to keep up with announcements, chat with fellow players and find people to play with.

This update adds a completely new tech tier, new cave system with new ores, mobs and items. To get to this new cave system, you have to start by killing the Pirate Captain. If you've already done this, you'll have to find a new one to kill.
Next update will focus on adding some more end game content that uses these new items, max HP etc.
Many objects have gotten a texture update and can now be rotated in all directions. This required some reworks to object rotations, so many of your objects will likely be rotated and have to be replaced. If you're not ready for this change, I have created a new beta branch that runs on 0.20.4. You can opt into it the same way you opted into this version.
