Quasar 是一个 Java 库，提供了高性能、轻量级的线程，类似 Go 语言的 Channel，Erlang 语言的 Actor 和其他异步编程工具。 Quasar 0.7.2 发布，更新内容如下： 新特性 A fully TCK-compliant Reactive Streams implementation based on Quasar Channels in the quasar-reactive-streams module 改进 Instrumentation optimisation has been introduced: methods that don't need instrumentation will be left untouched and this improves performance Instrumentation verification is more precise, it checks call sites (see #86) and it prints extended stack trace information on HotSpot JRE 8; in addition it works even without verification enabled (and without performance penalty) when an uncaught exception is thrown in a fiber Improved JDK8-optimised build, no duplicate classes anymore (see #91) Minor channels improvements and fixes Kotlin upgraded to 0.12.613(post-M12) and several other dependencies upgrade The @Suspendable annotation is now supported on individual interface methods rather than just on the whole interface 更多改进请看这里，下载：https://github.com/puniverse/quasar/archive/v0.7.2.zip。 Quasar 0.7.2 发布，Java 轻量级线程库下载地址
