NetBalancer

What's new in this version:

New file system APIs:
Added a new function, fs.readv (with sync and promisified versions). This function takes an array of ArrayBufferView elements and will write the data it reads sequentially to the buffers
A new overload is available for fs.readSync, which allows to optionally pass any of the offset, length and position parameters

Other changes:
dns:
- Added the dns.ALL flag, that can be passed to dns.lookup() with dns.V4MAPPED to return resolved IPv6 addresses as well as IPv4 mapped IPv6 addresses
http:
- The default maximum HTTP header size was changed from 8KB to 16KB
n-api:
Calls to napi_call_threadsafe_function from the main thread can now return the napi_would_deadlock status in certain circumstances
util:
Added a new maxStrLength option to util.inspect, to control the maximum length of printed strings. Its default value is Infinity
worker:
Added support for passing a transferList along with workerData to the Worker constructor
