io.js 1.5.0 发布，此版本值得关注的改进如下：

• buffer: 新 Buffer#indexOf() 方法

• fs: 在 'fs' 方法的  options 对象属性不再执行一个 hasOwnProperty() 检测

• tls: 解决了 PayPal 报告的类似 TLS 的内存泄漏问题

• npm: 升级 npm 到 2.7.0 版本

  • 145af65#4887 Replace calls to thenode-gyp script bundled with npm by passing the--node-gyp=/path/to/node-gyp option to npm. Swap in pangyp or a version of node-gyp modified to work better with io.js without having to touch npm's code!  (@ackalker)

  • 2f6a1df#1999 Only run stop and startscripts (plus their pre- and post- scripts) when there's no restart script defined. This makes it easier to support graceful restarts of services managed by npm.  (@watilde /@scien)

  • 448efd0#2853 Add support for --dev and--prod to npm ls, so that you can list only the trees of production or development dependencies, as desired. (@watilde)

  • a0a8777#7463 Split the list printed bynpm run-script into lifecycle scripts and scripts directly invoked via npm run-script. (@watilde)

  • a5edc17#6749 init-package-json@1.3.1: Support for passing scopes to npm init so packages are initialized as part of that scope / organization / team. (@watilde)

• TC: Colin Ihrig (@cjihrig) resigned from the TC due to his desire to do more code and fewer meetings.
