Send email to customers before an upgrade is started
Currently, the customers are expected to monitor the PI Square post here for see updates about a release : https://pisquare.osisoft.com/community/all-things-pi/pi-cloud-connect/release-notes.
The problem with this is that:
1) Not all customers are aware of this expectation
2) Customer will have to login to see the releases which is not very user friendly
It might be better to send the information via email.
