changelogs

Every vendor publishes release notes somewhere different. A GitHub release, a Steam patch note, a console firmware page, an IDE changelog nobody links to. What's New reads all of them and stores what it finds in one shape. Four read-only tools open that catalog to an agent: list_products and search_releases do what they sound like, whats_new takes the version you actually run and answers with only what shipped after it, and upgrade_notes takes the dependencies you are upgrading, from npm to Maven, and answers per package with the vendor's own breaking-change and migration sections — the ones a minor version number never announced. There is no key and no sign-in: point a client at https://whatsnew.fyi/mcp and start asking. Every entry keeps the provenance labels the site shows and links to the vendor's own notes, which are still the authoritative copy.
