io.js 2.2.0 发布，此版本值得关注的改进如下：

• node: Speed-up require() by replacing usage of fs.statSync() and fs.readFileSync() with internal variants that are faster for this use-case and do not create as many objects for the garbage collector to clean up.  #1801 .

• node: Resolution of pre-load modules ( -r or --require ) now follows the standard require() rules rather than just resolving paths(Ali Ijaz Sheikh) #1812 .

• npm: Upgraded npm to v2.11.0. New hooks for preversion , version , and postversion lifecycle events, some SPDX-related license changes and license file inclusions. See the release notes for full details.
