IO.js 1.7.1 发布，服务器 JS 引擎
5月23日 西安 OSC 源创会开始报名啦，存储、虚拟机、Docker 等干货分享IO.js 1.7.1 发布，此版本改进了对 ARM 的支持，现在 ARM 上面此版本能够顺利创建和测试了。
值得关注的改进如下：
[*] C++ API: Fedor Indutny contributed a feature to V8 which has been backported to the V8 bundled in io.js. SealHandleScope allows a C++ add-on author to seal a HandleScopeto prevent further, unintended allocations within it. Currently only enabled for debug builds of io.js. This feature helped detect the leak in #1075 and is now activated on the root HandleScope in io.js. (Fedor Indutny) #1395.

ARM: This>
[*] ARMv8 64-bit (AARCH64) is now properly supported, including a backported fix in libuv that was mistakenly detecting the existence of epoll_wait(). (Ben Noordhuis) #1365.
[*] ARMv6: #1376 reported a problem with Math.exp() on ARMv6 (incl Raspberry Pi). The culprit is erroneous codegen for ARMv6 when using the "fast math" feature of V8. --nofast_math has been turned on for all ARMv6 variants by default to avoid this, fast math can be turned back on with --fast_math. (Ben Noordhuis) #1398.
[*] Tests: timeouts have been tuned specifically for slower platforms, detected as ARMv6 and ARMv7. (Roman Reiss) #1366.

[*] b747593#7630 Don't automatically log all git failures as errors. maybeGithub needs to be able to fail without logging to support its fallback logic. (@othiym23)
[*] 78005eb#7743 Always quote arguments passed to npm run-script. This allows build systems and the like to safely escape glob patterns passed as arguments to run-scripts with npm run-script-- . This is a tricky change to test, and may be reverted or moved to npm@3 if it turns out it breaks things for users. (@mantoni)
