<Update label="v2.0.1" description="25 Aug 2026">
  `description-fix`

  Clarified list\_models description to reflect that it returns each model's ID, context window, and token limits but not per-model feature support (image input, PDF input, extended thinking), which is available via get\_model. Refreshed get\_model modelId example values to current models.

<Update label="v2.0.0" description="25 Aug 2026">
  `enhancement` `breaking-change`

  Breaking: scoped actions by auth type — admin API actions (users, workspaces, invites, api\_keys, org) now require admin\_api\_key, messages/models actions require standard API key. Removed old model enum values (claude-opus-4-0, claude-sonnet-4-0, claude-3-haiku-20240307), added latest models (claude-sonnet-5, claude-fable-5, claude-mythos-5, claude-opus-5, claude-opus-4-8, claude-opus-4-7). Improved pagination cursor descriptions for list\_models.
