[nginx-announce] njs-0.3.2

[Dmitry Volyntsev]

Hello,

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

This release mostly focuses on stability issues in njs core after regular
fuzzing tests were introduced.

Notable new features:
- Added ES6 template literals support:
: > var a = "Template", b = "literals"
: undefined
: > `${a} ${b.toUpperCase()}!`
: 'Template LITERALS!'

- Added ES9 RegExp "groups" object support:
: > /(?<r>(?<no>no)?(?<yes>yes)?)/.exec('yes').groups
{
  no: undefined,
  r: 'yes',
  yes: 'yes'
}
