If your license expiry date is June 28, 2022, it means you cannot use Aspose API(s) version(s) that would be released after this date. But you may continue to use any version that is released before the license’s expiry date and your license will never expire. In short, you cannot avail free/paid updates, new (upcoming) versions, hotfixes and other upgrades after this date. So, to use the upcoming updates and fixes, you have to purchase new license or update your subscription first.
