When you say list, do you mean the upgrade options in the UI or the TrueNAS Software Status | TrueNAS Documentation Hub page?
We’re at an awkward state in the release cycle with both 26-BETA.1 being available and 25.10.2.1 still being marked for Early Adopters. I don’t think this situation should happen too much in the future as we move to the one year release cycle, but the newer Early Adopter just bounced the earlier one from the status table for the time being. I would still expect it to be an option in the UI, but maybe the logic wasn’t built with this situation in mind. Might be worth a bug report if it isn’t.
I wouldn’t expect 25.10.2.X to move to General status at this point, but hopefully 25.10.3 will do so fairly quickly after some soak time.
