All the purchased versions include a twelve-month support period offering updates and technical support. After twelve months, users will be able to continue to use the software as it exists, but you would need to extend the support and maintenance. This means in order to receive updates and support for the software, you will have to purchase an extension.
As an example, the extension version of MDK-ARM-ES-LC is MDK-ARM-ES-SM-LC.
