Mongodb DeprecationWarning

• mongodb version：3.2.10

• express-session version：1.16.2

• connect-mongo version：3.0.0

• I found that connect-mongo triggered the warning。

• express server started with warning：

(node:494260) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to MongoClient.connect.

Part of code:

        app.use(
            session({
                secret: this.session.secret,
                cookie: {
                    httpOnly: true,
                    maxAge: 1000 * 60 * 60
                },
                resave: true, 
                saveUninitialized: false,
                store: new MongoStore({
                    url: this.session.dbUrl
                })
            })
        );

any idea when this is going to be pushed to NPM? The NPM package hasn’t been updated yet, so users downloading from there still receive the deprecation warning.
