Hello,

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

This release proceeds to extend the coverage of ECMAScript
specifications and modules functionality.

- Added initial ES6 modules support:
: // module.js
: function sum(a, b) {return a + b}
: export default {sum};
: // shell
: > import m from 'module.js'
: undefined
: > m.sum(3, 4)
: 7

You can learn more about njs:

Feel free to try it and give us feedback on:

- Github: https://github.com/nginx/njs/issues
