About Litmus
The blog feed says nothing; Litmus's real changelog sits undated in a separate scrape.
Two sources sit under this product and they do not agree. The dated feed is a deliverability and lifecycle education blog — footers, rebrands, preference centres, birthday sends, holiday prep — and announces no product change; one entry even carries the rebrand article's excerpt instead of its own, a scrape defect. The undated rows are the actual Litmus release archive: Email Guardian, Integrated Insights, Litmus Personalize, Litmus Assistant, and two dozen smaller Builder, Proof, and testing releases.
