Since version 2.0 there are four different editions available. By knowing what each of these edition offers you can pick what fits the best for your needs to only pay what you need.
In particular we actually offer only three different editions (basic, professional and enterprise). The fourth edition (educational) is feature wise identical with the enterprise edition, but free for educational purposes.
The commercial licenses also come with one year of support, which also includes free versions. However, the if you decide not to renew the license it will still continue to work, except that updates won’t be available until a renewal.
