值得关注的更新：

• url: url.resolve('/path/to/file', '.') now returns /path/to/ with the trailing slash, url.resolve('/', '.') returns /. #278 (Amir Saboury)

• tls: The default cipher suite used by tls and https has been changed to one that achieves Perfect Forward Secrecy with all modern browsers. Additionally, insecure RC4 ciphers have been excluded. If you absolutely require RC4, please specify your own cipher suites. #826 (Roman Reiss)
