Updates are how you stay in the store. What's New is part of the listing. A paste of ticket titles is not a listing. I write one change a stranger cares about.
The reader is not me
They are on a product page, not GitHub. Hangar's user wanted a deploy button. Monetra's user wanted profit, not a schema migration.
Metadata holds still apply
An update still needs the social media question answered. What's New does not skip Connect.
Keep it short
If I cannot say the change in two sentences, I do not have a What's New yet. I have a dump. The store is already asking people to notice a screenshot. I do not add noise.
