Declare a new instance with function, no more class constructor ?

[PaulRosset]

Hi,

I just downloaded the last release of node-wit (4.2.0) with
npm install --save node-wit

Then ,
const Wit = require('node-wit')

But Wit is no more a constructor but now a function, so it works with

const client = Wit.Wit({ accessToken: '<ACCESS_TOKEN>' })

In the doc, it's still saying that is a constructor.
Is it normal ?

Thanks :)
