All licensed users will be provided free updates to fix reported bugs or add new minor features. However, new versions which include major features and code compliance upgrades with a newer design code are considered paid upgrades. You decide if you want to pay for any subsequent upgrade.
If your annual Maintenance & Support Plan is active, then all updates to the current and new version will be free of charge, in addition the automatic web update system, and the access to tech support.
If you purchase an annual subscription, it includes Maintenance and Support, therefore all updates are included with your subscription.
