水面、というか水中での魚雷(ミサイル系武装)の強化が来たようです。

Oh and exploside warheads for missiles have a significant damage buff for being underwater 

 
とりあえずテンさん曰く-5 で威力が最大に到達し
威力4倍、爆発半径3倍 に至るのだとか。

I believe a number of blocks have changed in mass but probably the change in the mass of your ship will be to do with the change in mass of resource carrying (processed and raw) blocks.

These were actually increased in mass to help the player pull the COM down below the COB and increase ship stability- so line the bottom of your vehicle with these kinds of blocks.

あとリソース箱(未加工、加工済み)系の重量が変化。弾薬箱や燃料タンクが一気に鉄ブロックより5ほど重い具合に。RTGなんかも鉄には及ばないが結構重く。

とりあえずNickフォーラムの記事にちゃんと書けとwwwww
