New releases from Zoom and how to learn more

There is a couple of pages on their support site you can subscribe to:

General Release notes overview page:
https://support.zoom.us/hc/en-us/sections/201214205-Release-Notes

Release notes by Product (Only notifies for new products):
https://support.zoom.us/hc/en-us/sections/360008531112-Zoom-Releases-By-Product

From mid April they started doing a date based release note so you could actually get an update when stuff was happening:

One thing to note is that EU release is about 1 week behind the official release.

Finally there is the incident page https://status.zoom.us which mostly will give you alarms 
for stuff that does not concern us. But that is a statuspage.io site with the inherent options for subscriptions.
