Let me clarify what is actually in the datamine at the same time quoting the dataminers themselves. This will be technical so I apologize. Also please don't ask me about these. I'm not a dataminer and I am interpreting these info as best as I can so we can all understand.
Evidence of fence cutomization:
- mRemakeFence and mRemakeFenceScale were added to the bymls. "Remake" indicates customization.
New unused tool strings:
- SpnR (SpanneR), DStk (DishStack), GlDr (Glass Drink), Cnut (Coconut), Pitc (Pitcher), Trwl (Trowel), STWN, CoCa, TaDr, and SnBa. The last 4 strings are currently unidentified. But to put it simply, these are basically objects that villagers & NPCs can hold.
A lot of people have been waiting on those white fences since before launch even lol
As for the strings, I'm pretty sure CoCa is code for Coca Cola/the pop can you see villagers walking around with.
