Well, let's see. As our good raven Memory stated above, there's not been a whole lot of details released as they want us to discover them as we go, but they have released a number of teasers.

First, as the name suggests there is a whole plethora of building parts being added. Most are as yet unknown too us, but they have teased us with shingle roof tiles, wolves head ornamentation, shuttered windows, a new chest type, coin stacks and piles, a new type of iron door/wall (not fully sure which), and a few other things the look slightly off in the vids, but nothing I can place my finger on yet.

They have tweaked how shields work, giving some much needed love to the tower shield and with a focus on health being important to defensive gameplay while stamina is still offense focused. There are some weapon tweaks as well that will be mentioned in their next vid.

There is a new plantable material in the form of the onion. There is also speculation that the Darkwood Tile roofs will use a new Darkwood material to gather, though this isn't confirmed as yet. There is also the new Pukeberries to gather and three new types of meat (deer, boar, wolf) to replace raw meat.

They have also completely changed the cooking and food system, expanding it out from a simplistic placeholder to a full out crafting system on par with the Workbench and Forge. This means several new crafting station upgrades and probably some build items to place around them. Food is also broken down into health focused, stamina focused, or balanced recipes allowing you to more finely pick your playstyle. I also suspect that food will now have upgradeable tiers like equipment does, but that's just my personal speculation.
