HAProxy is so well known that it really doesn't need to. I mean, you wouldn't expect Facebook to mention the fact that it's a social network on every one of its blog posts.

And if you don't know of the product, just Google it.

It is a matter of choice. Do you mind adding a sentence for the people that are too lazy to do some search? Maybe if they are too lazy they are not interested in the product, but the cost of that sentence is negligible. Even Facebook was a lot less popular at some time and my mother asked me what is that.

The cost of the sentence is screen real estate, plus a distraction from the purpose of the post.

I sometimes feel the collective of spirit of HN can never be satisfied. If you do put that sentence in, someone will probably question why it's there :p

kzrdude, great feedback. These big version announcements gather the attention of people who may not be familiar with HAProxy and so, I'd say they are a unique case where we should introduce the product for newcomers.
