What changed, and what it means. Every piece carries a read: a link with no take is a bookmark, not a post.
Each item covers one change: a platform launch, a new capability, a deprecation, a policy, a measurement change or a case study. Each one links the announcement itself and says what it does to the numbers and the work. Pieces are dated and are not rewritten after publication. Errors are logged on the corrections page.
