- Fixed a bug where pipelined http requests would stall (Fedor Indutny) #3342.
- (Breaking) When parsing HTTP, don’t add duplicates of the following headers:Retry-After, ETag, Last-Modified, Server, Age, Expires.

src: (Breaking) Bump NODE_MODULE_VERSION To 47, this is necessary due to the V8 upgrade. Native add-ons will need to be recompiled (Rod Vagg) #3400.
