Yes, with the LB GCode license you get one year of updates, then your updates are frozen, but you can continue to run it at any version up to the latest available during your subscription period.
After that, if you renew 30 days prior to the expiration, you get and added month onto the next year and renewals are $30/year.
These licenses are good for running on two computers and you are not tied to any particular laser that runs the same OS (GRBL, ruida, Galvo, etc.)
