I agree, I think changing the title is a better solution than linking to the release notes, but I still think it makes sense to offer extra clarity.

The original title of the blog post is "Highlights from Git 2.33" which to me is a bit clearer that this is not release notes or any kind of "official" Git 2.33 announcement but rather someone's highlights about Git 2.33. I have no idea why the original submitter chose to edit the title like this.
