SugarCRM 6.5 still updated?

I'm a little bit confused. I know that sugarCRM no longer supports version 6.5 as of 2016, but there are still security patches being applied in 2017 as per:

http://support.sugarcrm.com/Resources/Security/sugarcrm-sa-2017-005/

Does this mean that no new functionalities will be added but security patches and bug fixes will still be applied?

Thank you
