If you use a framework and want to keep up-to-date with new releases then you can subscribe to that projects mailing list/twitter.
Non-users of the framework aren't likely to care very much about it.
Unless I'm missing something all this post is doing is taking up a front-page slot which could be used by a more worthy story.
There is an important security fix in this Rails version and for Rails devs, who have a huge presence on HN, it matters just like "the new Ubuntu version boots half a second faster" matters to many.
Minor release announcements of Firefox, Ubuntu, Python, Node.js have no place here.
If you're relying on HN to get updated when software on your production server has security vulnerabilities, then you're doing it wrong. You should be on the security mailing for any public facing software on your server.
The Rails security mailing list for those who aren't on it: http://groups.google.com/group/rubyonrails-security?pli=1
With only 36 points in 13 hours, users have already decided it's not front-page worthy. You didn't need to say anything.
We decide what's on the front page. If enough people vote, the article is worthy.
As per the quality thread the other day I think there is a view that voting isn't working, and we should figure out how to improve quality. This is my contribution :)
