Scala 2.12发布计划

　　Scala 2.12 会要求 Java 8，Scala 2.11 将会继续支持 Java 6。以下是 Scala 2.11 和 Scala 2.12 的共有特性：

• Compile lambdas efficiently using method handles. (Separate compatibility module needed on 2.11 – see below.)

• Java 8 interop (bidirectional):

• Fully integrate Miguel’s new back-end & optimizer (refactor code, test & document in-depth, remove old back-end).

• Style checker: an efficient, community-driven, platform for accurate coding style checking (built on top of the compiler).

• Collections: improve test coverage, performance, documentation (& modularize?)

• Improve documentation: focus on content. (This is a great place to start contributing, as well as on the tooling side of documentation.)

• Continue infrastructure improvements (sbt build, improve pull request validation & release automation, bug tracker cleanup and automation).

Scala 2.12 将会有更多的 Java 8 特性：

• Turn FunctionN into Functional Interfaces, so that Java 8 code can call higher-order methods in Scala without a wrapper.

• Support for @interface traits, which are guaranteed to compile to Java interfaces (useful for interop, performance and binary compatibility). This is a generalization of the above feature.

• Streams: integrate into Scala collections? (Anywhere from providing converters to replacing existing functionality.)

• Use the JDK’s forkjoin library instead of embedding our own. (Switch the global default ExecutionContext to be backed by the ForkJoinPool.commonPool().)

• SIP-20 Improved lazy val initialization (if time allows).
