The Laravel team released Laravel 5.8.18 with HTML as a valid extension option for views. With this release, you can pass a path to an HTML file which will not be compiled but rendered as-is—similar to how rendering a file with a .css extension works.

Next, you can provide a notification callback with Swift message, providing developers direct access to the Swift message before it is fired off:

$message = new MailMessage();
$message->withSwiftMessage(function ($message) {
  // ....
});

You can see the full list of fixes below, and the whole diff between 5.8.17 and 5.8.18 on GitHub. The full release notes for Laravel 5.8 are available in the GitHub 5.8 changelog:
