PHPMailer has announced that it has released PHPMailer 6.6.0 with minor updates in OAuth property and TLS error reporting.
PHPMailer 6.6.0 changes
PHPMailer 6.6.0 is a minor release that adds easier integration with different OAuth libraries, and better reporting of TLS errors.
Prior to 6.6.0, TLS errors that occurred in PHPMailer did not contain information to help web developers diagnose the problem. With the introduction of reporting of TLS errors, it will be much easier to identify and solve problems.
Prior to PHPMailer 6.6.0, it was also not easy to integrate OAuth libraries without extending the \PHPMailer\PHPMailer\OAuth class. 6.6.0 introduces OAuthTokenProvider that allows for easier integration with any OAuth2 token provider.
