No, there isn’t one. Actually there aren’t blog articles for each and every minor release - the latest blog article about minor versions was about 20.0.5. I think this one was made to announce the end of life for NC 18.
I do not understand what you need a blog article for, when you already got the information via the RSS feed?
Writing and coordinating release announcements is not that easy - there are so many channels like all the social media stuff, blog, forum, RSS, … I totally understand that noone wants to write a blog entry about such minor stuff
