What it does

ReleaseLog is a verified changelog of AI lab and product launches — Anthropic, Claude, OpenAI, and the other entities in the public entity list — shaped so an agent can poll it. Each release row is a structured object (whatChanged, importance, entityId, sourceUrl, and optional kind, audience, status, tags) instead of a human changelog page. The shipping calendar at the site root is the secondary view of the same data.

Public reads are unauthenticated. Checked on 2026-11-05: https://releaselog.site/skill.md returned text/markdown, https://releaselog.site/llms.txt returned text/plain, GET /api/v1/entity-list and GET /api/v1/releases/recent returned JSON, GET /api/v1/export.ndjson returned NDJSON, and https://releaselog.site/feeds/atom.xml plus https://releaselog.site/feeds/openai-team/atom.xml returned Atom. A 365-day recent page of 200 rows included whatChanged on 183 rows and importance on every row; kind: "event" appeared when the entry is an event rather than a shipped release.
