Hello,

I'm glad to announce a new release of NGINX JavaScript module (njs).

This release proceeds to extend the coverage of ECMAScript
specifications.

Notable new features:

- Object.assign() method:
: > var obj = { a: 1, b: 2 }
: undefined
: > var copy = Object.assign({}, obj)
: undefined
: > console.log(copy)
: {a:1,b:2}

You can learn more about njs:
