Tried to find why there was 3 releases on the same day but haven't found any blogg or thread explaining that
So why?
What are you talking about?
No.

I want to know why v20.1.5 and v.20.1.6 and v20.1.7 was released on the same day
Because the blog wasn't updated when they were released. If you read the announcements at the top of this forum, you will find the real release dates.
I'm on 20.1.4 and have checked for updates weekly but without any new updates. Today I saw 3 new updates and now I find newer than 20.1.4.
Strange
They were announced on the forum. If you had used firmware->updates it would have seen them too, it was just the blog was not updated therefore you would not have seen them using the blog widget.
Looking at https://opnsense.org/blog/ the last three blog posts were added on the same day. The blog is lagging behind due to COVID-19 and added all of them at once after the fact.
Can we move on now please?
