What is the default version used by Knex.js for the mysql client when no value specified

Question

The Knex.js documentation allows for a version to be set when using a client, in my case I'm using mysql, something like this:

  client: 'mysql',
  version: '5.7',
  connection: {
    host : '127.0.0.1',
    user : 'your_database_user',
    password : 'your_database_password',
    database : 'myapp_test'
  }
});

If I don't specify a value for version what default value will it use?

Per source code: https://github.com/tgriesser/knex/blob/master/src/client.js#L53

"version" exists for reference only, whichever version of mysql you're connecting to will be used.

As for which versions of MySql that are supported by knex, I'd direct you to their docs: https://knexjs.org/
