description: >-
  Langdock publishes a dated public product changelog covering model availability,
  platform features, and integrations. It is a product changelog rather than an
  API-versioning changelog — entries are not tagged with API versions, and API
  breaking-change notices are carried in the developer docs (for example the
  Assistants-to-Agents migration guide) rather than here.
