Release Highlight

db.addUser() and admin.addUser() removed

The deprecate addUser APIs have been removed. The driver maintains support across many server versions and the createUser command has support for different features based on the server's version, since applications can generally write code to work against a uniform and perhaps more modern server the path forward is for applications to send the createUser command directly.

See createUser documentation: https://www.mongodb.com/docs/manual/reference/command/createUser/

const db = client.db('admin');
// Example addUser usage
db.addUser(
  'myUsername', 
  'myPassword', 
  { roles: [ { role: 'readWrite', db: 'mflix' } ] },
  (error) => {
    if (error) {
      console.log('Failed to create user', error);
      return;
    }
    console.log('Created user!');
  }
);
// Example equivalent command usage
db.command(
  { 
    createUser: 'myUsername', 
    pwd: 'myPassword', 
    roles: [ { role: 'readWrite', db: 'mflix' } ] 
  },
  (error) => {
    if (error) {
      console.log('Failed to create user', error);
      return;
    }
    console.log('Created user!');
  }
);

collection.stats() removed

The collStats command is deprecated starting in server v6.2 so the driver is removing it's bespoke helper in this major release. The collStats command is still usable from manually running it via await db.command(). However, the recommended migration is to use the $collStats aggregation stage. You can find more information here: $collStats
