XMind Plus and XMind Pro are lifetime type software. Once ordering them, people can use XMind Plus/Pro forever and get any small updates for the ordered version for free. For example, if you purchase an XMind 7 Pro license key, you can update your XMind 7 v3.6.0 to v3.6.1 or v3.6.2, and etc. for free.
You may have to pay an extra upgrade fee from v3.6.x to v3.7.x, if you want to keep using the latest version. So we also offer an option, 2-year upgrade service, with a reasonable price. With the upgrade service, you can enjoy all upgrades within 2 years from the purchase date.
Please Note that the 2-year upgrade service can only be ordered while buying XMind Plus/Pro license. It's not sold separately.
If enabling this option while ordering XMind Plus or XMind Pro, the license you get will have the upgrade service information. So you can get the latest version within 2 years with this license.
