*   Allow call `assert_enqueued_email_with` with no block.

    Example:
    ```
    def test_email
      ContactMailer.welcome.deliver_later
      assert_enqueued_email_with ContactMailer, :welcome
    end

    def test_email_with_arguments
      ContactMailer.welcome("Hello", "Goodbye").deliver_later
      assert_enqueued_email_with ContactMailer, :welcome, args: ["Hello", "Goodbye"]
    end
    ```

*   Ensure mail gem is eager autoloaded when eager load is true to prevent thread deadlocks.

    *Samuel Cochran*

*   Perform email jobs in `assert_emails`.

    *Gannon McGibbon*

*   Add `Base.unregister_observer`, `Base.unregister_observers`,
    `Base.unregister_interceptor`, `Base.unregister_interceptors`,
    `Base.unregister_preview_interceptor` and `Base.unregister_preview_interceptors`.
    This makes it possible to dynamically add and remove email observers and
    interceptors at runtime in the same way they're registered.

*   Rails 6 requires Ruby 2.4.1 or newer.
