Hi,
My MCH got updated early today and I received both the email and the notification, but the website is yet to be updated: https://support.wdc.com/download/notes/WD_My_Cloud_Home_Firmware_Release_Notes.html
Which makes the email/notification pretty boring since it links to an out of date website… Would be more relevant to update the website and release notes before updating the devices.
Best,
AF
