I think it's not so much a complaint, as a suggestion to include a short recap of what the project is in the introduction of release announcements. I don't think OP was so much annoyed, as much as that they considered that it's a smart thing marketing-wise: those who don't know what the project is are unlikely to read on to the third paragraph.

See e.g. Rust, which does this really well: https://blog.rust-lang.org/2018/08/02/Rust-1.28.html
