To determine which version of PHPMailer you are using, you can access the version property of the PHPMailer class.

require 'PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
echo $mail->version;

6.1.7

The above code will output the version of PHPMailer that is currently being used.

Alternatively, you can look at the CHANGELOG.md file provided in the PHPMailer repository. This file contains a list of changes and updates made to the PHPMailer library, including the version number for each release.
