Upgrading license every year is optional. Just for your information, when you purchase a license for a product, you are authorized to use this license file with any new (and upcoming (official versions)) versions, hot fixes or interim releases of the component(s) for the next whole year. Moreover, your license will never expire if you use your license with the product’s version/hot fix that should be released before your subscription expiry date. Please note, if you need to use a version of the product(s) which is released after your subscription expiry date, then you must upgrade your subscription. For more details about licensing, please do contact or post a query in Aspose.Purchase forum.

Thank for your response
