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: 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.
