I think you're asking where we could find a software release schedule (or at least the "latest/current release"). I have no idea and it's something I mentioned in another thread.
Software release schedules for OTA updates are, unfortunately following the lead of smart phones (where by you only know about an update if you happen to (a) look in the right place at the right time or (b) follow forums/social-media/etc. platforms and beta-testers give insight as to what is coming, otherwise you have to trust that the update is "automatic" and will take place when it should).
Tesla was the same way .. if all works well, then you get the update notification (presumably when it's available for the general public). Unfortunately, I was never sure if I was on the latest release or not.
Seems Lucid may be following the same process (i.e. made available as "sprints" are delivered) .. So, updates will be staged when data transfer is possible and then we'd be notified of a pending upgrade. Hopefully, it'll work as intended.
Hopefully someone more knowledgeable than I can chime in and let us know if there is a repository that we can check to see what the latest, release version is.
