What is the difference between a version based license and a subscription based license?

Subscription based license has support expiration date one year from the date of registration. The license contains the support expiration date. You may install any product updates, including new product releases, until the support expiration date.

Version based license has no support expiration date. The license contains the version number instead of support expiration date. You may install product updates for that version of the product only, with no limitation. This license does not entitle you to the next version of the product. Version based license is available only for some products.
