# Changelog

User-visible API, model, capability, limit, pricing, and reliability changes.

## 2026-08-17

- Rebuilt the public documentation as an English-only, Markdown-first developer portal.
- Added generated OpenAPI 3.1 JSON/YAML, integrated API reference, raw Markdown pages, and `/llms.txt`.
- Made the public model catalog live from `GET /v1/models` with a timestamped fallback snapshot.
- Clarified total completion-token budgets, stateless Responses behavior, Anthropic-specific `529` mapping, combined vision upload limits, and Zero Data Retention metadata boundaries.
- Added contract, example, link, rendering, drift, and public-artifact leak validation.

Future entries include only changes that affect API users. Internal deployment and infrastructure details remain in the private operations knowledge base.
