[nginx-announce] njs-0.3.1

[Dmitry Volyntsev]

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 ES6 arrow functions support:
: > var materials = ['Hydrogen', 'Helium', 'Lithium']
: undefined
: > materials.map(material => material.length)
: [
:  8,
:  6,
:  7
: ]

: r.subrequest('/foo', rep => r.return(rep.status, rep.responseBody))
