io.js 2.3.1 发布，值得关注的更新内容： module: The number of syscalls made during a require() have been significantly reduced again (see #1801 from v2.2.0 for previous work), which should lead to a performance improvement (Pierre Inglebert) #1920. npm: Upgrade to v2.11.2 (Rebecca Turner) #1956. Upgrade to v2.11.3 (Forrest L Norvell) #2018. zlib: A bug was discovered where the process would abort if the final part of a zlib decompression results in a buffer that would exceed the maximum length of 0x3fffffff bytes (~1GiB). This was likely to only occur during buffered decompression (rather than streaming). This is now fixed and will instead result in a thrown RangeError (Michaël Zasso) #1811. 更多改进请看更新日志，下载：https://github.com/nodejs/io.js/archive/v2.3.1.zip。 IO.js 是为 V8 引擎编写的基于事件 IO 的实现。 构建要求： * `gcc` and `g++` 4.8 or newer, or * `clang` and `clang++` 3.3 or newer * Python 2.6 or 2.7 * GNU Make 3.81 or newer * libexecinfo (FreeBSD and OpenBSD only) io.js 2.3.1 发布，服务器 JS 引擎下载地址
