 PHPMailer 6.5.4 has just been released. It includes some minor PHP cross-
 version improvements and a safeguard against hosters disabling security
 functions.

 The version included with WP should be updated.

 Full details:

 * https://github.com/PHPMailer/PHPMailer/releases/tag/v6.5.4
 * https://github.com/PHPMailer/PHPMailer/compare/v6.5.3...v6.5.4

 I've reviewed the diff and the changes look sensible to me, so I would
 recommend an update at the earliest convenience.

 Previously: #53430, #53953, #54514
