To later visitors looking for help: You can be notified of new releases by subscribing to the RSS feed:
I’ve come to Support to give a heads-up that I subscribed to release-notes at the Watching First Post notification level months ago. But I only got my first notification from Discourse today. I’ve missed many notifications I should have received.
Weird.
I watched (set to tracking) Marketplace for a few months and didn’t miss any topic.
이 문제는 드물고 재현하기가 어려울 것이라고 생각했습니다. 기록을 남기고 해결책을 제시하고 싶었을 뿐입니다. 비슷한 Support 요청이나 Contribute > Bug 가 있는지 확실하지 않습니다.
또한, 저는 구체적으로 “첫 게시물 보기(Watching First Post)” 기능을 사용하고 있습니다. "추적(Tracking)"은 작동하지만 "첫 게시물 보기"는 작동하지 않는 것일 수도 있습니다.
As a temporary workaround, I see that release-notes topics rarely have more than 1-2 posts, so maybe the regular watch or tracking option would work for you on that for now.
Looking at your preferences @zjpcyo, it seems you don’t have any categories set to Watching First Post?
@moin has correctly pointed out that release-notes is a tag and not a category, and I can see that is in your Tag Notifications as Watching First Post. 
I’m still not sure why you wouldn’t receive any notifications for it though? I shall investigate further. 
That is because release-notes is a tag and not a category
I’d like to be notified by e-mail. So I believe that excludes Tracking.
I just want the announcements not the comments. That is why I chose Watching First Post instead of Watching.
As a sidenote, the ?order=created parameter solves the problem of recent comments knocking the topics out of order.
So if I want to peek at a topic list without subscribing, I can use that parameter in the address bar to sort topics by created date.
Ex.
https://meta.discourse.org/?order=created
As a practical matter, release-notes don’t appear to have that issue. But this can be useful in other cases.
Ex. Manjaro releases category:

I receive emails for releases but I’m set to ‘watching’ rather than ‘watch first’.
The only responses to release-notes topics are additional notes, so you won’t be bombarded with reply notification emails.
It looks like the solution is in the split topic.
