### Agents Platform

- **Agent branching and deployments**: Added a complete version control system for agents, enabling teams to create branches, iterate on agent configurations in isolation, and merge changes when ready. New endpoints include `POST /v1/convai/agents/{agent_id}/branches` for creating branches, `POST /v1/convai/agents/{agent_id}/branches/{source_branch_id}/merge` for merging, and `POST /v1/convai/agents/{agent_id}/deployments` for creating deployments. Drafts can also be created and deleted via the new drafts endpoints. See the [Branches](/docs/api-reference/agents/branches/list) and [Deployments](/docs/api-reference/agents/deployments/create) documentation for details.
- **WhatsApp account management**: Added `PATCH` and `DELETE` endpoints for WhatsApp Business accounts, allowing you to update and remove connected WhatsApp accounts from agents.
- **Conversation agent name**: The [Get conversation](/docs/api-reference/conversations/get) endpoint now returns `agent_name` in the response for easier identification of which agent handled a conversation.
- **Error type tracking**: Added `error_type` field to conversation event models for improved debugging and error categorization.

### Knowledge Base

- **Folder management**: Added support for organizing knowledge base documents into folders. New endpoints include [Create folder](/docs/api-reference/knowledge-base/create-folder) for creating folders, [Move document](/docs/api-reference/knowledge-base/move-document) for moving single documents, and [Bulk move](/docs/api-reference/knowledge-base/bulk-move) for moving multiple documents at once.

### Tools

- **Enhanced tools listing**: The [Get tools](/docs/api-reference/tools/list) endpoint now supports filtering and pagination with new query parameters including `search`, `page_size`, `types`, `sort_by`, `sort_direction`, and `cursor`. Response now includes `next_cursor` and `has_more` fields for pagination.

### Music

- **Song metadata enhancements**: Added `bpm` and `time_signature` fields to song metadata for richer audio analysis information.

### Studio

- **Caption style templates**: Added `caption_style_template_overrides` field to project models, allowing customization of caption styling per template.
- **Video dubbing project type**: Added `dub_video` to the project creation type enum.
- **Publishing metadata**: Added `last_updated_from_project_unix` timestamp to publishing and project metadata.

### Workspaces

- **Seat type management**: Introduced new `SeatType` enum with `seat_type` and `workspace_seat_type` fields, deprecating the previous `workspace_permission` and `workspace_role` fields.
- **Workspace analytics permission**: Added `workspace_analytics_full_read` to the `PermissionType` enum for granular analytics access control.
