I don't think this should be the headline "improvement", if it needs
mentioning at all it should be further down, perhaps as a separate para
near the end detailing things which have gone away rather than presented
as a feature.

PVH is a preview isn't it? Shouldn't that be made clear to avoid
disappointing? (likewise for anything else like that in this list), I'd
suggest separate paragraphs for new features, new preview and new
experimental stuff.
