A perpetual license is valid for the current version of Geneious Prime at the time of purchase (e.g. Geneious Prime 2019). This includes any updates (e.g. 2019.0.1 and 2019.1) that are released for that version, regardless of when they are released. You can continue to use this version for as long as you wish. To access future versions (e.g. Geneious Prime 2020), you will need to purchase an upgrade or switch to a subscription plan.
We provide technical support to holders of a valid license for the latest version and the one before that (e.g. Prime 2019 and R11). We release a new version at most once per year.
