First I want to thank the NomadBSD developers for the work they have done and are doing with this really cool operating system, which is my daily driver since years!
I have just done two installations of NomadBSD 141R on different notebooks (Dell and Asus).
I only updated by Octopkg about 50 qt5 and qt6 library packages.
I say I only upgraded via Octopkg because I think it would be safest not to mix FreeBSD with NomadBSD because of moderator @Ime’s clarification in this post: 14.1-release - #17 by lme
I look forward to the completion and rollout of the upgrade program, as it is not yet finished.
To upgrade NomadBSD, you currently need to write the new image to a USB and reinstall. Partial updates can be managed with freebsd-update and Octopkg until the updater is complete.
