io.js 1.4.3 发布，值得关注的改进：
stream: Fixed problems for platforms without writev() support, particularly Windows. Changes introduced in 1.4.1, via #926, broke some functionality for these platforms, this has now been addressed. #1008 (Fedor Indutny) arm: We have the very beginnings of ARMv8 / ARM64 /
AARCH64 support. An upgrade to OpenSSL 1.0.2 is one requirement for full
support. #1028 (Ben Noordhuis) Add new collaborator: Julian Duque (@julianduque)
