io.js 1.5.0 發布，服務器端 JS 引擎

IO.js 是為 V8 引擎編寫的基于事件 IO 的實現。io.js就是node.js的一個分支，或者說是替代技術。io.js是node.js是原班開發隊伍由于不滿官方運營商 Joyent 而另起爐灶fork出來的一個分支，它目前來看完全兼容 npm ，和node.js的語法。io.js在其官方主頁 https://iojs.org 上顯示1.0穩定版支持Linux、Win32、Win64和Mac平臺。

io.js 1.5.0 發布，此版本值得關注的改進如下：

• buffer: 新 Buffer#indexOf() 方法

• fs: 在 'fs' 方法的  options 對象屬性不再執行一個 hasOwnProperty() 檢測

• tls: 解決了 PayPal 報告的類似 TLS 的內存泄漏問題

• npm: 升級 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.

已知問題

• Windows still reports some minor test failures and we are continuing to address all of these as a priority. See #1005.

• Surrogate pair in REPL can freeze terminal #690

• Not possible to build io.js as a static library #686

• process.send() is not synchronous as the docs suggest, a regression introduced in 1.0.2, see #760 and fix in #774

• Calling dns.setServers() while a DNS query is in progress can cause the process to crash on a failed assertion #894
