SQLEditor includes 12 months of upgrades (both major and minor). After 12 months you may have to pay for major upgrades.
Buy Upgrade Assurance and you get 12 additional months of upgrades included Buying Upgrade Assurance is the cheapest and easiest way to get access to these upgrades and subscribing will save you money compared to buying upgrades when they are released.
Note that this is a one-off payment for 12 months only. In 12 months time we will normally contact you and ask if you would like to purchase another 12 months of assurance, but it doesn't automatically renew.
