- xmlとparser-combinatorが別のjarになった http://d.hatena.ne.jp/xuwei/20130726/1374809559
- case classやメソッドの22制限がなくなった scala/scala#2305
- 「value classのvalがpublicでないといけない」という制限がなくなった scala/scala#2965 scala/scala#3113
- Java8のようなSingle Abstract Methodの糖衣構文を(experimantalだが)サポート scala/scala#3037
- パターンマッチの際に使われる
unapplyの戻り値型が、Optionではなく「isEmpty: Booleanとget: Aをもっていればどんな型でもよい」と、制限が緩くなった - http://d.hatena.ne.jp/xuwei/20131005/1380887673
- scala/scala#2848
scala.util.contrll.TailCalls.TailRecにflatMapが追加された scala/scala#2865- view boundが非推奨になった scala/scala#2909
- リフレクションが
スレッドセーフになった(またバグが見つかったらしい) scala/scala#3029
