Beat me to it! I am so hyped for so many things, and I'm happy that they're going to release the content over time rather than hold it all for one giant update. It's nice to have a genuine roadmap now.
Dungeons and Boss Fights
The bosses look very MMO-esque with all the red areas you have to dodge.
We've been working on rocket boots, a mechanical hookshot, a glider, a mining drill, and a spyglass.
Oh yeah, Hytale is definitely going to be more like Terraria now.
Carryable Objects
Being able to carry storage was one of my favorite things about Vintage Story, nice that it's coming here as well.
Abilities and Runes
Seems interesting, I guess this is going to be the game's version of classes. It ties in with the elemental system they talked about ages ago.
Boats
Finally!
The Hytale engine is gaining support for real transparency! This means that stained glass and window blocks will now be possible.
Finally!
Mod Browser: Coming in 2-3 weeks (Update 6)
By far the most exciting thing in the update IMO. Keeping your mods updated was a nightmare, and CurseForge is terrible to use.
After a lot of bug fixing updates, it's so reassuring to know that new content is coming pretty soon. The pace of development is very impressive. They did all this in the time it takes Mojang to add a few animals to the game.
