io.js 2.3.1 发布，服务器 JS 引擎

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 .
