@jeanpierrraubry: to my understanding, it is currently EA. At least [Release notes] Vanha Rauma 4.4.0 doesn’t mention any general release. At OBS, it is still absent.
As I don’t have any official device, I have no idea how such release is pushed to users. I am assuming that you have to subscribe for them somehow before general release.
Anyway, I hope 4.4.0 will be soon released for all and, in few days after that , will be made available at OBS.
