PHPMailer 6.10.0

This is a feature and maintenance release introducing full support for RFC 6531 SMTPUTF8, meaning that you are now free to use Unicode characters in email addresses, such as JøeÜser@example.com, and everywhere else, without any complicated encoding schemes. Using this feature requires that you send through a mail server that advertises support for SMTPUTF8. For full details see SMTPUTF8.md.
