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:

- Function constructor:
: > var sum = new Function('a, b', 'return a + b');
: undefined
: > sum(2, 3)
: 5

You can learn more about njs:
