In the last day of April, HMD Global started rolling the monthly update for April for a number of devices. Phones that started receiving the update are Nokia 7 plus, Nokia 6.1 Plus, Nokia 6.1 and Nokia 5.1. The changelog for all devices mentions just the security patch.
You can check if the update is available going to Settings->System->System Update. My Nokia 6.1 just received and so did Marin’s 7 plus, so I guess the availability is broader. As always, it goes in waves, so some will still have to wait.
If you have any of the devices mentioned above, do leave a comment if the update is available and if you noticed any changes. 🙂
