Right now, the link title is not even that, but just "Python 3.9". I wouldn't be surprised if it was an after the fact change; I've observed that HN admins never let "X Y.Z Released" or "What's New In X Y.Z" headlines stand but change them to "X Y.Z" or even just "X" almost immediately.

It's a strange HN-ism that puzzles me - "OK, what's so important about Foo 3.14?" There is a rule that is (barely IMO) on point though in the posting guidelines you linked to:

> If the title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."

3.9.0 was released as stable today:

> Release Date: Oct. 5, 2020

> This is the stable release of Python 3.9.0

Wait until you read that they’re moving to yearly releases...

I love python but these short release cycles can be really annoying.
