All License Keys that have (or have had) a Linux activation have been retroactively renewed up to today’s date, even if their update period has expired. This will allow all Linux LightBurn users to use the final Linux release of LightBurn. That includes LightBurn version 1.7 and all subsequent patches to it, up until the release of LightBurn version 1.8.
If your update period extended beyond today, and you are a Linux user, that future date remains as the end of your update period.
