• You can now set Resolverthe local IP address that the instance uses to send its requests.

•  

  Two new methods have been added to control the NODE_V8_COVERAGEcoverage of V8 activated by environment variables.

•  

   

  WorkerExamples now has a performanceproperty that has a eventLoopUtilizationmethod that can be used to collect information 'online'and 'exit'information on the events between helper event loop utilization.

 

 

 

• With new --heapsnapshot-near-heap-limit=max_countexperimental command line flags, it is now possible to automatically generate a heap snapshot when the V8 heap usage is close to the heap limit.
