Yes, all upgrades will be free for one year. It’s called maintenance.
However, your purchased license will always work. So all versions you receive during your maintenance will always work and never expire. When your maintenance expires, all received versions will still work. It’s only versions released after maintenance expiration that you won’t be able to activate, unless you renew your maintenance.
Note that we extend all maintenances for current owners of ExeOutput 1.7.x so that they can upgrade to ExeOutput 2 when it is released.
