Are CC update email notifications possible?

At our side we decided to go with a delay policy when switching to newer CC versions due to initial bugs usually crippling the creative process. So we turned off auto-updating in the CC app and just a few testers switch to 2020 before the whole department gets the OK.

This means in turn that all minor updates like 21.0.1 => 21.0.2 are also skipped. Naturally the possible update it is reported in the CC app with the update counter. But if you are testing just 1 of many on-hold updates, you may easily miss a minor bug fix this way.

I googled already for some time and searched the community but I am not sure anymore which information is up-to-date and relevant due to being years old posts or having a lacking description for my case. Can someone confirm if any of the following options will send me an email notification for any update release and which is the best approach:

1. Following a CC app community - I see the new community has announcements for new updates but following a community will also send lots of other posts (is there a way to filter it simply without an email filter to prevent bad filter settings) and since I just noticed it, I am not sure how announcements are handled with following
2. Subscribing to the secutiry notifications https://helpx.adobe.com/security.html seems to only send security updates and not each update may have it
3. Is this https://blogs.adobe.com/deployment/2015/12/want-to-know-when-creative-cloud-product-updates-get-released.html only relevant to the administrator account?
4. Maybe simply monthly cheking the fix pages per app is https://helpx.adobe.com/photoshop/kb/fixed-issues.html, are updates always released in the middle of a month? No matter how I search Adobe's pages I can't find an update schedule/history log

Maybe I am overthinking it and the administrator has something like that already? But is it possible to have some kind of subscription for sa normal user besides the mentioned options?
