Michael using different language than NVIDIA to describe the state of the driver is confusing. I guess he considers New Feature Branch to be stable, except the first 555 versions released under that designation were (IMO, based on my system and watching the feedback forums and changelogs for 560/565) not very stable from a user perspective… which I suspect is likely why NVIDIA has not released any 555/560/565 to Production Branch for ~6 months now. And it’s still not clear which major version is planned for Production Branch…
