PHPMailer 6.0.1 已发布，PHPMailer 是一个 PHP 编写的电子邮件发送库，功能十分齐全，被大量开源项目使用，如 WordPress、Drupal、1CRM、SugarCRM、Yii、Joomla 等等。
更新内容：
Use shorter Message-ID headers (with more entropy) to avoid iCloud blackhole bug
Switch to Symfony code style (though it's not well defined)
CI builds now apply syntax & code style checks, so make your PRs tidy!
CI code coverage only applied on latest version of PHP to speed up builds
Remove composer.lock - it's important that libraries break early; keeping it is for apps
Rename test scripts to PSR-4 spec
Make content-id values settable on attachments, not just embedded items
Add SMTP transaction IDs to callbacks & allow for future expansion
Expand test coverage
